Hello, currently I am using a 5th generation Airport Extreme and it worked perfectly fine until the update. Recently, after the update, my iPhone and MacBook Air would connect to 2.4 GHz channel as before but 5.0 GHz channel does not connect my Apple products. Is it happening because of the Firmware update? Shall I uninstall the update or can it be fixed even without the roll-back?
Airport Extreme Wi-Fi Auto Channel Issue?
