I have some issues with my new 5G unit.
I have a T-Mobil SIM installed but it will only install with Firmware ver. 8.1.1 I tried to install ver. 8.1.2 but it looses the SIM information and will not repopulated it so I rebooted to the older firmware and the SIM information is there.
I have no way to change cellular bands to pick the one I want. There does not appear to be anyway to do a manual selection like the manual states.
I keep getting repeated DNS failure problems on a local Wifi system that I can easily connect to with my table, PC or phone but the Max tries and fails with the DNS failure message.
I am very new to all this so I may have something set wrong.
