1. The mini router doesn’t have 802.1x protocol built in. You need to opkg remove wpad-mini and opkg install wpad if you want 802.1x.

  2. Probably you can get a more expensive full band modem what works around the world without changing the module. I have some choice but never fully tested them by ourselves.

  3. From firmware v2.241 (still in testing) we have mwan3 built-in. It can switch the network automatically. But it is built in ping and it will have a duration network break when it switch network.
