What are the influences when band-select is configured for AP? - Ruijie Community

After AP identifies STA, dual-band STAresponds to only one of N (which can be configured) authentication requests of2.4G frequency band. Generally, if a dual-band STA detects that WLAN has the BSSID at both the 2.4G frequency band and 5G frequency band, whenre-authentication request at one frequency band is not responded, it will tryanother frequency band. However, some dual-band STAs may always sendauthentication request to the same frequency band. Assuming that a dual-bandSTA sends M authentication requests to 2.4G frequency band before trying 5Gfrequency band, when N is larger than M, the STA can connect to 5G frequencyband; otherwise, the STA connects to 2.4G frequency band. Whichever frequency band is used, if the dual-band STA try the 2.4G frequency band first, there is always min (M,N) requests are neglected, resulting in prolonged STA connectiontime. The prolonged STA connection time depend on the STA driver. For example,if STA sends authentication requests at an interval of 00 ms and four authentication requests are neglected, the STA connection time is prolonged by400 ms.
