MacBook Air 2015 Wifi problem reconnection
Hello everyone,
I have the problem with Wi-Fi on MacBook Air 2015 with the Big Sur version, every time I disconnect and want to reconnect, the connection itself takes a long time and in the meantime a password entry table appears about 5 times and the connection failed under the message. It will succeed on the 5th attempt, but it will only switch to the 2.4 ghz network. The router is a TP-Link Archer 6 (with 2.4 and 5ghz). If I miraculously manage to connect to 5ghz then there is about 10 Sec lag connection once every 2 min. I tried to clear the list of wifi networks and reset the router to the factory settings, unfortunately nothing helped, including smc, VRAM, etc. I have no problem with other devices. Does anyone know where could be a problem please ?
MacBook Air 13″, macOS 11.2
