I have a question
The problem is that the Deco often changes ISP to my neighbor country (Sweden), even when roaming is off.
I live about 20 km away from the border to Sweden (i live in Norway)
And even if i manually changes my Mobile ISP and choose the right carrier in the Doco app, and of course ROAMING is off, it still changes to Swedish ISP, and i loose 5G band/connection, and it jumpes to Swedish 4g (not even LTE+) but only LTE, with very weak signal
So up to 10 times a day i have manually set everything back again so i can use a Norwegian ISP, and connect a 5g cellular band.

I have tried to reset the Deco to factory setting many times, do all the setup again, moved the deco to the best place (closer to the cell tower where i live).I even tried a 5g external antenna, but still, it changes back to the Swedish ISP, and very very weak LTE signal.
 

How do i make this stop? How can i manually choose the right Band (n28 and B20) and KEEP it there?

Numerus times i tried to reset (turn on and off roaming, taking the sim in and out, i even took it to the 5G cellular tower (standing right beside it, got superspeed, but after a few minutes it changes to the Swedish ISP. 
I complained to Norwegian ISP, asking for new sim-card 2 times! with no luck.

And what the firmware? When i go the nordic site of firmware download, i get acyally 2 different firmware?
My info is:  X80-5G(1.0) -  2.1.3 Build 20240111 Rel. 74550 . So i guess i have v1?

This

And then this:

Both is v1, but the first wont even install.

Wich is right?
