According to an example, an AP may obtain an influence index for each of antenna combinations, and determine antenna combinations whose influence indices are smaller than or equal to a pre-determined threshold to be valid antenna combinations. The antenna combinations may include antennas not more than the maximum number of transmitting links supported by the AP. Each influence index may indicate the influence of an antenna combination on default antenna combinations of neighboring APs operating on the same channel. The AP may adjust the available transmission rates supported by the AP according to the largest number of antennas in the valid antenna combinations. The AP may select a transmission rate from the range for a frame, determine the number of antennas corresponding to the selected transmission rate, and select an antenna combination in which the number of antennas equals the determined number of antennas from the valid antenna combinations for transmitting the frame.

Selecting antenna combination

The present disclosure describes promoting roaming of a wireless terminal in a wireless local area network (WLAN). The AP obtains signal quality and/or data transmission quality of the wireless terminal periodically, and determines whether the obtained signal quality and/or data transmission quality of the wireless terminal satisfies a predetermined threshold. Upon determining that the predetermined threshold is not satisfied, the AP proactively sends a probe response frame to the wireless terminal. The probe response frame notifies the wireless terminal of a wireless signal strength of the AP to promote roaming to a neighboring AP.

Promoting wireless local area network (WLAN) roaming

A method of establishing network connection between a network device and a WLAN is disclosed. The method includes: determining whether there is previous security association between the network device and the WLAN at the time of requesting for network association, and establishing a new security association between the network device and the WLAN using security data generated in the course of establishing the previous security association if there is the previous security association.
