But identifying WLAN networks using SSID instead of SSID + BSSID + Channel (I guess this is how GLv3 firmware and OpenWRT built-in wireless client mode does) is pretty much the industry standard, I guess? Like any iPhone, Mac, Windows and Android devices. They all consider networks with the same SSID will have the same password. And this is how things should be and will be in most of the cases. Since this allows wireless roaming to be possible.
So like my original bug report (or more like feature request, sorry for not putting it in the v3 feature request thread) states: It would be nice if the wireless repeater actually remembers SSID only and tries to connect to the known networks ignoring the channel and BSSID differences. (or offers a choice to users) Otherwise every single time you go to a new places, like Starbucks, you have to scan and add a new network again. Even though there are already like 5 “Starbucks” in your “saved network” list.
