I have an additional Problem with my MT1300.
I wanted it to connect to a 2.4 GHz Wifi, this WIfi is open and has multiple Access Points around the hotel with the same name but different channel.
However, The MT1300 does not connect. I scanned all WIfi, selected the hotel wifi (only one was listed) then it takes some time (I see the rings for waiting) but then it does not connect at all. No Wifi connection is done on main page. Firmware is openwrt-mt1300-3.203-1012
