It took me a while to find a router or router board that performs the way I need it to while out traveling.
The Banana Pi R3 only comes with a power outlet adapter. This means the antenna and everything else needed for a fully functional router you need to purchase separately. They are the items that I have purchased so far.
Next up will be a Wifi 6 module and a 4G LTE module.
EDIT: Don’t use this adapter, at full load transferring files over wifi, it does not supply enough power for the R3. Now I am using a Ryobi 18V battery and a step-down to 12v converter to power the device by battery.
