Nighthawk M2 or Alternative (PERMANENT)

Bit of a noob here but special circumstances. Australia QLD - new home - No internet available (except Elon just launching)

Got a Poynting XPOL 5g/4g on the roof now and get awesome speeds even out of a loaner Nighthawk M2 - I've tried several other routers and very disappointed with speeds - even the supposedly great Huawei 4G Router 3 Prime Modem, B818 - 263 - but average results.

Soooo my question.

Can anyone confirm a Powered router that is comparable with the M2 or M5 but more permanent.

My guess is its the fact that the M2 can aggregate up to 5 bands.

Not sure if anything else in the Netgear range that is not mobile can do so too.

I know I can just get an M5 or M2 and pull the battery out but I'm after a more permanent solution.

Any recommendations will be very much appreciated.

With thanks
