Hello,
I have a Surface Book 2, that I bought in the UK. Wifi works as expected on 2.4 and 5 GHz bands when the access point is visible. It turns out, when it comes to the 5GHz band, my laptop can only see up to channel 140. In the UK, I found out these channels are not available to regular WiFi. Now I need access to channels 145 and above and cannot see a single one of them with my laptop. Is there a way to change the wifi region on this laptop? I have tried
- All Windows region settings on the laptop
- Reset the internet
- Roll back the driver (Marvell Avastar)
- disable all other network device drivers except Wan Miniport ones
Nothing works. Did not try yet:
- OEM drivers
- Registry values
- Refresh the system (don't think it will work)
Could anybody help me, please?
Regards,
Joao

The FCC has had a ruling for a number of years about 802.11d -
https://www.silextechnology.com/unwired/fcc-update-802-11d-world-wide-roaming
has as good an explanation as any I've seen. So this can't be changed by
registry or a driver AFAIK. Microsoft has not responded further in this thread
and I personally don't have any other info on this..
