  The ROM 12 is a non-rewritable memory that stores a control program executed by the MFP 1, and stores programs for executing a wireless LAN simple setting process shown in FIG. 3 and a setting changing process shown in FIG. . The RAM 13 is a rewritable volatile memory. The flash memory 14 is a rewritable nonvolatile memory, and is assigned an identification information memory 14a, an old network setting memory 14b, and a new network setting memory 14c.

  The identification information memory 14a stores identification information that can identify the BOX 31 on the network. In this embodiment, a MAC address (Media Access Control address) is stored.

  The old network setting memory 14b automatically sets (changes) the setting items related to the wireless LAN of the own apparatus (MFP 1) so that data communication with the AP 51 is possible in the Inf mode using the wireless LAN simple setting function. In this case, it is a memory for storing setting contents related to the wireless LAN before the setting is changed.

  The new network setting memory 14c stores the setting contents related to the new wireless LAN after the setting change when the wireless LAN simple setting function is used to automatically set (change) the setting items related to the wireless LAN of the own device 1. It is a memory for storing.

  The wireless LAN communication control circuit 15 performs various controls of data communication by the wireless communication 200 (of the wireless LAN system), and includes a wireless LAN easy setting function (for example, an AOSS (registered trademark) function, a WPS function, etc.) 15a And a wireless LAN antenna 16.

The data is demodulated into document data.

  Next, the wireless LAN simple setting process executed by the CPU 11 of the MFP 1 will be described with reference to FIGS. In the following description, it is assumed that both the MFP 1 and the BOX 31 are capable of data communication with each other in the Ad mode. The wireless LAN simple setting process is a process executed when the MFP simple setting button 17a of the MFP 1 is pressed. As shown in FIG. 3, in the wireless LAN simple setting process, first, a setting change process is executed (S1).

  Here, the setting change process (S1) executed by the CPU 11 of the MFP 1 will be described with reference to FIG. As shown in FIG. 4, in this setting change process, first, in order to confirm the existence of the BOX 31 on the network to which the MFP 1 is connected, the MAC address is obtained by SNMP (Simple Network Management Protocol). Specifically, an SNMP packet for requesting notification of a MAC address is generated, and the SNMP packet is transmitted to a terminal device existing on the network (S21). Then, it is determined whether the MAC address acquired from the terminal device that has received the SNMP packet matches the MAC address stored in the identification information memory 14a (S22).

  As a result, when it is determined that they do not match (S22: No), it is determined that the BOX 31 does not exist, and the process proceeds to S29. On the other hand, when it is determined that they match (S22: Yes), it is assumed that the BOX 31 exists, and a “wireless LAN simple setting function execution start request” is transmitted to the BOX 31 (S23). It is determined whether a predetermined time (timeout time) has elapsed since the “execution start request” was transmitted (S24).

  If the predetermined time has not elapsed (S24: No), it is determined whether or not an “execution start request response indicating that the wireless LAN easy setting function execution start request has been received” transmitted from the BOX 31 has been received. (S25). On the other hand, when the predetermined time (timeout time) has elapsed in the process of S24 (S24: Yes), the process proceeds to S29.

  When the “execution start request response” is not received in the process of S25 (S25: No), the process returns to the process of S24, and the processes of S24 and S25 are repeated. On the other hand, when the “execution start request response” is received in the process of S25 (S25: Yes), for example, “Set BOX starts on the LCD 18. Press the AP simple setting button and wait for a while. Is displayed (S26).

  Next, after receiving the “execution start request response” transmitted from the BOX 31, it is determined whether a predetermined time (timeout time) has elapsed (S27). S27: No), it is determined whether the “setting completion notification indicating that the setting (change) has been completed” transmitted from the BOX 31 has been received (S28). On the other hand, in the process of S27, when the predetermined time (timeout time) has elapsed (S27: Yes), the process proceeds to S29.

  In the process of S29, in order to notify that the setting related to the wireless LAN of the BOX 31 has not been completed normally, for example, the LCD 18 displays “The wireless LAN simple setting function of BOX could not be used” (S29). The process proceeds to S42. In the process of S28, when the “setting completion notification” has not been received (S28: No), the process returns to S27, and the processes of S27 and S28 are repeated.

  On the other hand, when the “setting completion notification” is received in the processing of S28 (S28: Yes), a “setting completion notification response indicating that the setting completion notification has been received” is transmitted to the BOX 31 (S30). The LCD 18 displays “Start MFP setting. Please press the AP simple setting button again and wait for a while” (S31), and display the various settings related to the current wireless LAN in the old network of the flash memory 14. Store in the setting memory 14b (S32).

  Next, the wireless LAN simple setting function of the MFP 1 is executed (S33). When the MFP 1 starts executing the wireless LAN simple setting function, special data communication is executed between the MFP 1 and the AP 51, and the wireless LAN of the own apparatus 1 is related to the data communication with the AP 51 in the Inf mode. Setting items are automatically set (changed).

  Next, after executing the wireless LAN easy setting function of the MFP 1, it is determined whether or not a specified time (timeout time) has elapsed (S34). If the specified time has elapsed (S34: Yes), for example, the LCD 18 Displays “The wireless LAN easy setting function of the MFP could not be used” (S36), and the process proceeds to S42.

  On the other hand, in the process of S34, if the specified time has not elapsed (S34: No), it is determined whether the setting of the wireless LAN of the MFP 1 has been completed (S35). If the setting of the wireless LAN of the MFP 1 has not been completed (S35: No), the process returns to S34, and the processes of S34 and S35 are repeated. When the setting of the wireless LAN of the MFP 1 is completed in the process of S35 (S35: Yes), various setting contents regarding the set new wireless LAN are stored in the new network setting memory 14c (S37). The various settings related to the wireless LAN are temporarily returned to the contents of the old network setting memory 14b (S38).

  That is, it returns to the state in which data communication can be performed directly with the BOX 31 in the Ad mode. Then, a “switch instruction to Inf mode” is transmitted to the BOX 31 (S39), and it is determined whether or not a specified time (timeout time) has elapsed since the “switch instruction to Inf mode” is transmitted to the BOX 31 (S40). ).

  In the process of S40, when the predetermined time has elapsed (S40: Yes), the process proceeds to S42. In the process of S42, for example, “MFP and BOX settings are canceled” is displayed on the LCD 18 (S42), and the setting change process is terminated. On the other hand, in the process of S40, if the predetermined time has not elapsed (S40: No), it is determined whether or not the “switch execution notification” transmitted from the BOX 31 has been received (S41), and “switch execution notification”. Is not received (S41: No), the process returns to the process of S40, and the processes of S40 and S41 are repeated.

  On the other hand, when the “switch execution notification” is received in the process of S41 (S41: Yes), the various settings related to the wireless LAN of the MFP 1 are returned to the contents of the new network setting memory 14c (S43). That is, it returns to a state where data communication with the AP 51 is possible in the Inf mode. And this setting change process is complete | finished.

  Only when it is confirmed that both MFP 1 and BOX 31 are capable of data communication with AP 51 in the Inf mode by the setting change process shown in FIG. 4, both the communication settings of MFP 1 and BOX 31 are set via AP 51. So that they can communicate with each other. That is, when one of MFP 1 and BOX 31 cannot perform data communication with AP 51 in the Inf mode, both the communication settings of MFP 1 and BOX 31 are not changed, so that MFP 1 and BOX 31 cannot perform data communication. This can be suppressed.

  Returning to the description of FIG. When the setting change process (S1) is completed, it is next determined whether the settings of both the MFP 1 and the BOX 31 have been completed normally (S2). If the setting of one of the MFP 1 and the BOX 31 is not normally completed (S2: No), the wireless LAN simple setting process is terminated. On the other hand, when the settings of the MFP 1 and the BOX 31 are both completed normally (S2: Yes), an SNMP packet requesting notification of the MAC address is generated, and the SNMP packet is transmitted to a terminal device existing on the network. (S3).

  Then, it is determined whether the MAC address acquired from the terminal device that has received the SNMP packet matches the MAC address stored in the identification information memory 14a (S4). If it is determined that they match (S4: Yes) ), For example, the message “Communication with BOX is possible. MFP and BOX settings have been completed normally” is displayed on the LCD 18 (S5), and the wireless LAN simple setting process is terminated. The user can confirm whether the wireless LAN simple setting process has been normally executed in the MFP 1 by checking the LCD 18.

  On the other hand, if it is determined in the process of S4 that they do not match (S4: No), for example, “Communication with BOX is not possible. Check network settings of MFP and BOX.” Is displayed on LCD 18 (S6). ) The wireless LAN simple setting process is terminated.

  With the wireless LAN simple setting process shown in FIG. 3, when the MFP easy setting button 17a of the MFP 1 is pressed, the MFP 1 and the BOX 31 can each execute the wireless LAN simple setting function. Therefore, even if the user operates the MFP 1 and the BOX 31 and does not execute the wireless LAN simple setting function of each device 1, 31, if the user operates the MFP 1, the wireless LAN simple setting of each device 1, 31 is performed. Since each function can be executed, it is easy to use. Further, it is possible to cause the LCD 18 to display a result as to whether the MFP 1 and the BOX 31 have been changed to a state in which data communication can be performed with each other via the AP 51 in the Inf mode.

  Further, since the MFP 1 is a multi-function device, and the BOX 31 is a device that mainly controls communication using the telephone line network 100, the MFP 1 also has a housing (see FIG. 1) than the BOX 31. The display area of the LCD is also large. In the present embodiment, since the user operates the BOX 31 while looking at the LCD 18 of the MFP 1, more information can be displayed on the LCD 18 at a time than when the BOX 31 is directly operated while looking at the LCD 39 of the BOX 31. it can. Therefore, the setting state of the BOX 31 and the progress of the setting can be displayed in more detail, and user convenience can be improved.

  Next, a request execution process executed by the CPU 32 of the BOX 31 will be described with reference to FIG. In the following description, it is assumed that both the MFP 1 and the BOX 31 are capable of data communication with each other in the Ad mode. The request execution process is a process that is repeatedly executed after the main power supply of the BOX 31 is turned on until the main power supply is shut off.

  As shown in FIG. 5, in the request execution process, first, it is determined whether or not the “SNMP packet” transmitted from the MFP 1 has been received (S51). If the “SNMP packet” is received (S51: Yes). ), “MAC address” is transmitted to the MFP 1 (S52). On the other hand, if the “SNMP packet” has not been received (S51: No), the process proceeds to S53.

  Next, it is determined whether or not the “wireless LAN simple setting function execution start request” transmitted from the MFP 1 has been received (S53). When the “execution start request for the wireless LAN simple setting function” has not been received (S53: No), the process returns to S51, and the processes of S51 to S53 are repeated.

  In the process of S53, when the “execution start request for the wireless LAN simple setting function” is received (S53: Yes), an “execution start request response” is transmitted to the MFP 1 (S54), and the current wireless LAN is related. Various setting contents are stored in the old network setting memory 35a of the flash memory 35 (S55). Next, the wireless LAN simple setting function of the BOX 31 is executed (S56), and it is determined whether the specified time (timeout time) has elapsed since the wireless LAN simple setting function was executed (S57).

  In the BOX 31, when the wireless LAN simple setting function is executed, special data communication is executed with the AP 51, and setting items related to the wireless LAN of the own device 31 are set so that data communication with the AP 51 is possible in the Inf mode. Set (change) automatically. After the setting is completed, the BOX 31 is in the Inf mode, and is in a state where data communication with the AP 51 is possible, but data communication with the MFP 1 is impossible.

  In the process of S57, when the specified time has elapsed (S57: Yes), the wireless LAN easy setting function of the BOX 31 is not normally executed, so the process proceeds to S66. On the other hand, in the process of S57, when the specified time (timeout time) has not elapsed (S57: No), it is determined whether the setting of the wireless LAN of the BOX 31 is completed (S58). If the setting of the wireless LAN of the BOX 31 is not completed (S58: No), the process returns to S57, and the processes of S57 and S58 are repeated.

  In the process of S58, when the setting of the wireless LAN of the BOX 31 is completed (S58: Yes), various setting contents regarding the set new wireless LAN are stored in the new network setting memory 35b (S59).

  Next, in order to notify the MFP 1 of the completion of setting, various setting contents regarding the wireless LAN of the BOX 31 are once returned to the contents of the old network setting memory 35a (S60). That is, it returns to the state in which direct data communication with the MFP 1 is possible in the Ad mode. Then, a “setting completion notification” is transmitted to the MFP 1 (S61), and it is determined whether a specified time (timeout time) has elapsed since the “setting completion notification” is transmitted to the MFP 1 (S62).

  In the process of S62, when the predetermined time has elapsed (S62: Yes), the process proceeds to S66. On the other hand, if the predetermined time has not elapsed (S62: No), it is determined whether the “setting completion notification response” transmitted from the MFP 1 has been received (S63), and the “setting completion notification response” is displayed. If not received (S63: No), the process returns to the process of S62, and the processes of S62 and S63 are repeated.

  On the other hand, if a “setting completion notification response” is received in the processing of S63 (S63: Yes), the specified time (timeout time) has elapsed since the reception of the “setting completion notification response” from the MFP 1 It is determined whether or not (S64). If the predetermined time has elapsed (S64: Yes), the process proceeds to S66. In the process of S66, various setting contents regarding the wireless LAN of the BOX 31 are returned to the contents of the old network setting memory 35a (S66). Then, it returns to the process of S51 and repeats each process of S51-S66.

  On the other hand, if the predetermined time has not elapsed in the processing of S64 (S64: No), it is determined whether or not the “instruction for switching to Inf mode” transmitted from the MFP 1 has been received (S65). If the “inf mode switching instruction” has not been received (S65: No), the process returns to S64, and the processes of S64 and S65 are repeated.

  On the other hand, if a “switch instruction to Inf mode” is received in the process of S65 (S65: Yes), a “switch completion notification” is transmitted to the MFP 1 (S67), and various settings related to the wireless LAN of the BOX 31 are made. The contents are returned to the contents of the new network setting memory 35b (S68). That is, it returns to a state where data communication with the AP 51 is possible in the Inf mode. And it returns to the process of S51 and repeats each process of S51-S68.

  When the “request for starting execution of the wireless LAN simple setting function” transmitted from the MFP 1 is received by the request execution process shown in FIG. 5, the execution of the wireless LAN simple setting function of the BOX 31 is started, and the BOX 31 Various settings related to the wireless LAN can be set (changed) so that data communication with the AP 51 is possible.

  Also, after the wireless LAN simple setting function is executed and the setting has been changed normally (for example, after changing to the Inf mode), the setting is temporarily returned to the setting before the change (for example, Ad mode) and the setting is made to the MFP 1. A “setting completion notification” can be sent to indicate completion. When performing data communication in the Inf mode, both the MFP 1 and the BOX 31 perform data communication via the AP 51. Therefore, when there is a malfunction (communication failure or the like) in the AP 51, the MFP 1 and the BOX 31 Data communication may not be performed normally. However, since data communication is performed in the Ad mode, even if a defect occurs in the AP 51, it is not affected. Therefore, the MFP 1 can accurately detect whether the setting of the BOX 31 has been changed normally.

  Next, a second embodiment of the present invention will be described. In the second embodiment, only the parts different from the first embodiment will be described. The ROM 12 (not shown) of the MFP 1 stores programs for executing a wireless LAN simple setting process shown in FIG. 6 to be described later, an MFP setting changing process shown in FIG. 7, and a BOX setting changing process shown in FIG. 8, and a ROM 33 (not shown) of the BOX 31. ) Stores a program for executing a request execution process of FIG. 9 to be described later.

  Next, a simple wireless LAN setting process executed by the CPU 11 of the MFP 1 according to the second embodiment will be described with reference to FIGS. In the following description, it is assumed that both the MFP 1 and the BOX 31 are capable of data communication with each other in the Ad mode.

  This process is executed when the MFP easy setting button 17a of the MFP 1 is pressed. In addition, about the step which performs the process same as 1st Embodiment mentioned above, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 6, in this wireless LAN simple setting process, first, an MFP setting changing process is executed (S81). Here, the MFP setting change process (S81) executed by the CPU 11 of the MFP 1 will be described with reference to FIG. As shown in FIG. 7, in this MFP setting change process, first, various setting contents regarding the current wireless LAN are stored in the old network setting memory 14b (S91). Next, for example, “MFP setting starts. Please wait for a while by pressing the AP simple setting button” is displayed on the LCD 18 (S92), and the wireless LAN simple setting function of the MFP 1 is executed (S93). .

  When the MFP 1 starts executing the wireless LAN simple setting function, special data communication is executed between the MFP 1 and the AP 51, and the setting related to the wireless LAN of the own device is enabled so that data communication with the AP 51 is possible in the Inf mode. The item is set (changed) automatically.

  Next, after executing the wireless LAN easy setting function of the MFP 1, it is determined whether or not a specified time (timeout time) has elapsed (S94). If the specified time has elapsed (S94: Yes), for example, the LCD 18 Displays “MFP wireless LAN easy setting function could not be used. MFP and BOX settings are cancelled.” (S96), and the process proceeds to S98.

  On the other hand, in the process of S94, if the specified time has not elapsed (S94: No), it is determined whether the wireless LAN setting of the MFP 1 has been completed (S95). If the setting of the wireless LAN of the MFP 1 is not completed (S95: No), the process returns to S94, and the processes of S94 and S95 are repeated.

  In the process of S95, when the setting of the wireless LAN of the MFP 1 is completed (S95: Yes), various setting contents relating to the set new wireless LAN are stored in the new network setting memory 14c (S97), and S98. Move on to processing. In the process of S98, various setting contents related to the wireless LAN of the MFP 1 are returned to the contents of the old network setting memory 14b (S98). That is, it returns to the state in which direct data communication with the BOX 31 is possible in the Ad mode. Then, the MFP setting change process is terminated.

  Returning to the description of FIG. When the MFP setting change process (S81) is completed, it is next determined whether the setting of the MFP 1 has been completed normally (S82). If the setting of the MFP 1 has not ended normally (S82: No), the wireless LAN simple setting process ends.

  In the process of S82, when the setting of the MFP 1 is normally completed (S82: Yes), a BOX setting change process is executed (S83). Here, the BOX setting change process (S83) executed by the CPU 11 of the MFP 1 will be described with reference to FIG.

  As shown in FIG. 8, in the BOX setting change process, first, the processes of S21 and S22 (see FIG. 4) are executed. In the process of S22, when it is determined that the MAC address acquired from the terminal device that has received the SNMP packet does not match the MAC address stored in the identification information memory 14a (S22: No), the BOX 31 does not exist. Then, the process proceeds to S108.

  On the other hand, if it is determined in the process of S22 that they match (S22: Yes), for example, the BOX 31 is present and, for example, the LCD 18 displays “BOX setting starts. Please wait for a while” (S101). Then, a “communication setting change start request” is transmitted to the BOX 31 (S102). Next, it is determined whether a specified time (timeout time) has elapsed since the “communication setting change start request” is transmitted to the BOX 31 (S103). In the process of S103, when the predetermined time has elapsed (S103: Yes), the process proceeds to S108. On the other hand, when the predetermined time has not elapsed (S103: No), it is determined whether or not the “response to change start request indicating that the communication setting change start request has been received” transmitted from the BOX 31 has been received. (S104) If the “change start request response” has not been received (S104: No), the process returns to S103, and the processes of S103 and S104 are repeated.

  On the other hand, when the “change start request response” is received in the process of S104 (S104: Yes), the newly set (changed) various settings of the wireless LAN stored in the new network setting memory 14c. Is encrypted and transmitted to the BOX 31 (S105).

  For example, data may be encrypted and transmitted, or encryption wireless communication 200 may be performed. Examples of the encryption method of the wireless communication 200 include WEP, TKIP, and AES. By encrypting and transmitting data, it is possible to prevent unauthorized access to the AP 51 and unauthorized browsing and manipulation (falsification) of data.

  The data that is encrypted and transmitted to the BOX 31 includes, for example, setting contents for the MFP 1 to perform data communication with the AP 51 and setting contents for the MFP 1 to use TCP / IP. The setting contents for data communication with the AP 51 include, for example, the communication mode, authentication type, encryption mode, encryption key type, password (encryption key) setting contents, and the like. Note that the setting contents (parameters) of these setting items are automatically set for each setting item by the processing of S93 (see FIG. 7) described above.

  More specifically, one of the Ad mode and Inf mode is set as a parameter for the communication mode, and the authentication type is Open System, Shared Key, WPA-PSK, and WPA2-PSK. The highest security level that can be used by the MFP 1 and the BOX 31 is set as a parameter.

  Also, the encryption mode is set as a parameter according to the authentication type among None (none), WEP, TKIP, and AES, and the encryption key type is none, WEP Key, Among the temporary keys, those corresponding to the authentication type are set as parameters. No password (encryption key) is set when the type of encryption key is none, and a unique password is set when the type of encryption key is WEP Key or a temporary key. Is set.

  On the other hand, the setting content for using TCP / IP corresponds to, for example, the IP address acquisition method, default gateway, WINS setting, WINS server, DNS server setting content, and the like. Note that the setting contents (parameters) of these various setting items are set when parameters are automatically set for each setting item by the above-described processing of S93 (see FIG. 7) or by the user in advance. It may be set (changed).

  More specifically, in the IP address acquisition method, one of DHCP and AUTO (automatic selection) is set as a parameter, and the IP address of the communication device that is the default gateway is set as the default gateway. In the WINS setting, when the IP address acquisition method is DHCP, Auto is set, and when the IP address acquisition method is AUTO, Static is set.

  The WINS server is set with the primary address and secondary address of the WINS server, and the DNS server is set with the primary address and secondary address of the DNS server.

  Next, it is determined whether the specified time (timeout time) has elapsed since the encrypted data (that is, the data of the setting item relating to the newly set (changed) wireless LAN) is transmitted to the BOX 31 (S106). . If the predetermined time has elapsed (S106: Yes), the process proceeds to S108.

  On the other hand, in the process of S106, if the predetermined time has not elapsed (S106: No), “change completion indicating that the setting of the setting item related to the wireless LAN has been normally completed” encrypted and transmitted from the BOX 31 is completed. It is determined whether or not “notification” has been received (S107). If “notification of completion of change” has not been received (S107: No), the processing returns to S106, and each processing of S106 and S107 is repeated.

  On the other hand, when the “change completion notification” is received in the process of S107 (S107: Yes), the processes of S39, S40, S41, and S43 (see FIG. 4) are executed to execute this BOX setting change process. finish. In the process of S40, if the specified time (timeout time) has elapsed since the transmission of the “Inf mode switching instruction” to the BOX 31, the process proceeds to S108. In the process of S108, for example, the message “The network setting of the BOX could not be changed. The setting of the MFP and the BOX is canceled” is displayed on the LCD 18 (S108), and the setting change process is terminated.

  Only when it is confirmed by the BOX setting change process shown in FIG. 8 that both the MFP 1 and the BOX 31 are capable of data communication with the AP 51 in the Inf mode, both the communication settings of the MFP 1 and the BOX 31 are changed. To enable communication with each other. Therefore, it is possible to prevent the MFP 1 and the BOX 31 from entering a state where data communication is impossible.

  Returning to the description of FIG. When the BOX setting change process (S83) is completed, it is next determined whether or not the setting of the BOX 31 has been completed normally (S84). When the setting of the BOX 31 is not normally completed (S84: No), the wireless LAN simple setting process is terminated. On the other hand, in the process of S84, when the setting of the BOX 31 is normally completed (S84: Yes), the processes of S3 to S6 (see FIG. 3) are executed, and the wireless LAN simple setting process is terminated.

  Next, the request execution process executed by the CPU 32 of the BOX 31 will be described with reference to FIG. In the following description, it is assumed that both the MFP 1 and the BOX 31 are capable of data communication with each other in the Ad mode.

  This process is a process that is repeatedly executed after the main power supply of the BOX 31 is turned on until the main power supply is shut off. In addition, about the step which performs the process same as 1st Embodiment mentioned above, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 9, in this process, first, the processes of S51 and S52 are executed. Next, it is determined whether a “communication setting change start request” transmitted from the MFP 1 has been received (S121). If the “communication setting change start request” has not been received (S121: No), the process returns to S51, and the processes of S51 to S121 are repeated.

  In the process of S121, when a “communication setting change start request” is received (S121: Yes), a “change start request response” is transmitted to the MFP 1 (S122), and various settings related to the current wireless LAN are set. Is stored in the old network setting memory 35a (S123). Next, it is determined whether or not a predetermined time (timeout time) has elapsed since the “change start request response” was transmitted to the MFP 1 (S124).

  If the specified time has elapsed (S124: Yes), the process returns to the process of S51, and the processes of S51 to S124 are repeated. On the other hand, in the process of S124, if the specified time (timeout time) has not elapsed (S124: No), whether or not “data of various settings of wireless LAN” transmitted from MFP 1 has been received. Is determined (S125). If “data of various setting contents of the wireless LAN” has not been received (S125: No), the process returns to the process of S124, and the processes of S124 and S125 are repeated.

Then, various setting contents regarding the wireless LAN of the BOX 31 are set in the contents of the new network setting memory 35b (S127). If the various settings of the wireless LAN included in the received data are correct, the BOX 31 is set (changed) to a state in which data communication with the AP 51 is possible in the Inf mode by the process of S127.

  Next, it is determined whether or not the wireless communication 200 can be performed with the AP 51 (S128). If the wireless communication 200 cannot be performed with the AP 51 (S128: No), various setting contents regarding the wireless LAN of the BOX 31 are The contents of the old network setting memory 35a are restored (S129). That is, it returns to the state in which direct data communication with the MFP 1 is possible in the Ad mode. And it returns to the process of S51 and repeats each process of S51-S129.

  On the other hand, when the wireless communication 200 is possible with the AP 51 in the process of S128 (S128: Yes), in order to notify the MFP 1 of the completion of the change of the communication setting, various setting contents regarding the wireless LAN of the BOX 31 are The contents of the old network setting memory 35a are once restored (S130). That is, it returns to the state in which direct data communication with the MFP 1 is possible in the Ad mode.

  Here, since the MFP 1 is in the state of data communication by encryption, the “change completion notification” is transmitted to the MFP 1 by data communication by encryption (S131). Then, it is determined whether a specified time (timeout time) has elapsed since the “change completion notification” was transmitted to the MFP 1 (S132). If the predetermined time has elapsed (S132: Yes), the process returns to S51, and the processes of S51 to S132 are repeated.

  On the other hand, if the predetermined time has not elapsed in the process of S132 (S132: No), the process of S65 (see FIG. 5) is executed. In the process of S65, when the “instruction for switching to the Inf mode” transmitted from the MFP 1 has not been received (S65: No), the process returns to the process of S132, and the processes of S132 and S65 are repeated. On the other hand, in the process of S65, when a “switch instruction to Inf mode” is received (S65: Yes), the processes of S67 and S68 are executed. And it returns to the process of S51 and repeats each process of S51-S68.

  When “data of various wireless LAN setting contents” transmitted from the MFP 1 is received by the request execution process shown in FIG. 9, various settings related to the wireless LAN of the BOX 31 are set based on the received data. Can be set (changed) so that data communication is possible.

  As described above, in the second embodiment, only the MFP 1 is caused to execute the wireless LAN simple setting function, and data related to various setting items of the wireless LAN obtained by the execution is transmitted from the MFP 1 to the BOX 31. The BOX 31 sets (changes) various setting items related to the wireless LAN of the BOX 31 based on the received data. Therefore, the user simply presses the AP easy setting button 51a of the AP 51 once, and the MFP 1 and the BOX 31 are set. Various setting items related to the wireless LAN can be set.
