To how, according to the network Frequency Band Selection information of terminal equipment, be that terminal equipment selects network frequency range to be illustrated below.As shown in Figure 2, step S102 comprises the following steps:
In step S201, receive the connection request from terminal equipment;
In step S202, whether sense terminals equipment first connection; When terminal equipment is first connection, execution step S203; When the non-first connection of terminal equipment, execution step S205;
In step S203, to terminal equipment, push connectivity option;
In step S204, receive from the selected connectivity option of terminal equipment execution step S207.
In step S205, the used network frequency range of judgement terminal equipment;
In step S206, according to the used network frequency range of terminal equipment, be that terminal equipment is selected current network frequency range;
In step S207, connect terminal equipment.
Wherein, in step S202, when sense terminals equipment is first connection, turn to step S203, when sense terminals equipment is non-first connection, turn to step S205.In step S203, in the connectivity option that router pushes to terminal equipment, at least include default network frequency range, the connectivity option that can also include default network frequency range and one or more alternative network frequency ranges, for example, default network frequency range can be made as the network frequency range of 2.4gHZ, and alternative network frequency range can be made as the network frequency range of 5.0gHZ.In step S204, in the connectivity option that terminal equipment pushes at router, select one of them, by router, receive this selection result, and be terminal equipment interconnection network frequency range according to this selection result.
As shown in Figure 3, router pushes two connectivity options that comprise 2.4gHZ and 5.0gHZ to terminal equipment, and user selects wherein one in this connectivity option, as 2.4gHZ or 5.0gHZ, and clicks " confirmation ", represents chosen successfully; Or click " cancellation " reselects.
In disclosure embodiment, in step S202, the connection request of terminal equipment comprises the MAC Address of terminal equipment, and router can be searched corresponding network Frequency Band Selection information according to the MAC Address of terminal equipment, thereby judges whether first connection of terminal equipment.When the MAC Address by terminal equipment can find the network Frequency Band Selection information of corresponding terminal equipment, illustrate that terminal equipment is non-first connection, when the MAC Address by terminal equipment can not find the network Frequency Band Selection information of corresponding terminal equipment, illustrate that terminal equipment is first connection.Adopting is originally the method for embodiment, can judge rapidly and accurately whether first connection of terminal equipment, and then according to judgment result is that terminal equipment selects network frequency range.
In disclosure embodiment, step S206 comprises:
When the used network frequency range of terminal equipment is default network frequency range, whether sense terminals equipment has the ability that connects alternative network frequency range, that is to say, detects the network frequency range whether router has matched termination device network concatenation ability.If terminal equipment has the ability that connects alternative network frequency range, whether detect the signal strength signal intensity of current default network frequency range lower than predetermined threshold, when the signal strength signal intensity of default network frequency range is during lower than predetermined threshold, select alternative network frequency range as the current network frequency range of terminal equipment.
When the used network frequency range of terminal equipment comprises default network frequency range and alternative network frequency range, whether detect the signal strength signal intensity of current default network frequency range lower than predetermined threshold, when the signal strength signal intensity of default network frequency range is during lower than predetermined threshold, select alternative network frequency range as the current network frequency range of terminal equipment.
Like this, can avoid terminal equipment to use the weak frequency range of signal strength signal intensity and cause normally connecting wireless network, terminal equipment is connected to the good network frequency range of signal strength signal intensity, making terminal equipment accessing wireless network faster and better.
In above-described embodiment, by current network frequency range and predetermined threshold are compared to the signal strength signal intensity of learning current network, can be made as-70dB of predetermined threshold wherein, when the signal strength signal intensity detecting is during higher than-70dB, the signal strength signal intensity that this network frequency range is described meets the demands, and when the signal strength signal intensity detecting is during lower than-70dB, illustrate that the signal strength signal intensity of this network frequency range does not meet wireless network connection request, use other network frequency ranges instead and connect terminal equipment.
For example, when terminal equipment was only used 2.4gHZ to connect, whether sense terminals equipment has the ability that connects 5.0gHZ, if terminal equipment can connect 5.0gHZ, whether the signal strength signal intensity that detects current 2.4gHZ is lower than-70dB, when lower than-70dB, terminal equipment is connected to 5.0gHZ; If terminal equipment does not possess the ability that connects 5.0gHZ, terminal equipment is connected to 2.4gHZ.
When terminal equipment had both been used 2.4gHZ, while using again 5.0gHZ to connect, whether the signal strength signal intensity that detects current 2.4gHZ lower than-70dB, when the signal strength signal intensity of current 2.4gHZ is during lower than-70dB, terminal equipment is connected to 5.0gHZ.
When the signal strength signal intensity due to 2.4gHZ network frequency range is lower than-70dB, in the time of need to connecting terminal equipment in 5.0gHZ network frequency range, as shown in Figure 4, can send and remind to terminal equipment, terminal equipment be connected to 5.0gHZ network frequency range by terminal equipment after confirming.

For example, after the connection request of router receiving terminal apparatus, directly terminal equipment is connected to 2.4gHZ, and the signal strength signal intensity of Real-Time Monitoring 2.4gHZ, when the signal strength signal intensity of 2.4gHZ is during lower than predetermined threshold-70dB, router will be kicked terminal equipment off from 2.4gHZ, like this, terminal equipment will attempt being connected to 5.0gHZ, thereby obtains better wireless signal.
In disclosure embodiment, the method also comprises: record the MAC Address of terminal equipment and the network frequency range that this connection is selected.List can be set in router, and for recording the MAC Address of the terminal equipment that is connected to router and this terminal equipment, this connects the network frequency range of selection, while facilitating terminal equipment to carry out connecting next time, router can directly be judged the used network frequency range of terminal equipment, and then is that terminal equipment is selected current network frequency range according to the used network frequency range of terminal equipment.
