- the channel designation section 701 designates a channel to be searched.
- the channels are designated sequentially in ascending order of channel number from channel 1 to channel 13.
- the wireless LAN interface 117 searches the designated channel (channel 1 when the loop is executed for the first time) for an access point.
- the overflow determination section 702 determines in a step S803 whether or not the sum of the found access point count and the stored access point count is larger than the result area count. In other words, the overflow determination section 702 determines whether or not the sum of the number of access point data items stored in the memory and that of access points found in the present search is larger than the capacity of the memory. If the overflow determination section 702 determines that the sum of the found access point count and the stored access point count is larger than the result area count, the process proceeds to a step S804.
- the replacement section 703 determines whether or not the radio field intensity of an access point data item stored in the search area 620 is higher than that of an access point data item stored at the bottom of the result area 630. In other words, in this step, it is determined which of an access point data item obtained by the present search and an access point data item already stored satisfies a predetermined specific condition (i.e. which has a higher radio field intensity) . If a plurality of access point data items are stored in the search area 620 as in the case of the search result 607, the access point data items are sequentially subjected to this processing.
- a predetermined specific condition i.e. which has a higher radio field intensity

- the replacement section 703 determines in the step S804 that the radio field intensity of the access point data item stored in the search area 620 is higher than that of the access point data item stored at the bottom of the result area 630, the process proceeds to a step S805.
- the replacement section 703 replaces the access point data item stored at the bottom of the result area 630 with the access point data item stored in the search area 620.
- the sort section 704 sorts the access point data items stored in the result area 630 in descending order of radio field intensity.
- the replacement section 703 determines in the step S804 that the radio field intensity of the access point data item stored in the search area 620 is lower than that of the access point data item stored at the bottom of the result area 630, the process proceeds to a step S807.
- the access point data item stored in the search area 620 is lower in radio field intensity than any of the access point data items stored in the result area 630, the former is not stored in the result area 630.
- access point data items having high radio field intensity are sequentially stored in the result area 630.
- the replacement section 703 determines whether or not there remains an access point data item that has not yet undergone the determination processing in FIG. 804. If there remains an access point data item that has not yet undergone the determination processing in FIG. 804 (YES to the step S807), the process returns to the step S804, wherein a next access point data item is subjected to the determination processing. On the other hand, if all access point data items stored in the search area 620 have already undergone the determination processing in FIG. 804 (NO to the step S807), the process proceeds to a step S808.
- step S803 determines in the step S803 that the sum of the found access point count and the stored access point count is smaller than the result area count.
- the result receiving section 404 stores the access point data item stored in the search area 620 in the result area 630. Then, in a step S811, the sort section 704 sorts the access point data items stored in the result area 630 in descending order of radio field intensity, and then the process proceeds to the step S808.
- the channel designation section 701 determines whether or not it is necessary to designate a next channel. When all of the thirteen channels have not been searched, the channel designation section 701 determines that it is necessary to designate the next channel, and the process returns to the step S801. Then, in the step S801, the channel designation section 701 designates the next channel, and the steps S802 et seq. are executed.
- the channel designation section 701 determines in the step S808 that it is not required to designate a next channel, and the process proceeds to a step S809.
- the panel controller 401 causes the console panel 110 to display such a search result list screen as illustrated in (C) of FIG. 3, as an access point search result.
- the access point search is performed on a channel-by-channel basis instead of searching all the channels at a time, and then access point data items are sequentially stored in the result area.
- the access point data items are sequentially stored in descending order of radio field intensity depending on the capacity of the result area. Therefore, it is possible to reduce the access point data items.
- an access point desired to be connected by a user exists near the user and has a high radio field intensity.
- the present embodiment has the same hardware configuration as that of the first embodiment, and is distinguished from the first
- an access point search method which is a combination of the conventional access point search method and the access point search method described in the first embodiment. Therefore, components corresponding to those in the first embodiment are denoted by the same reference numerals , and
- the conventional access point search method is executed, whereby access point search is performed on all the channels. Then, when the search gives a larger amount of access point data (data amount ) to be stored than the capacity of the result area in the RAM 103, the conventional access point search method is switched to the access point search method of the first embodiment, whereby access point search is performed sequentially of all the channels on a channel- by-channel basis. More specifically, a comparison is made between the data amount defined by the number of access point data items of wireless access points found through the access point search performed of all the channels and the memory capacity, whereby it is
