Windows 10 can't see wifi channel 12 or 13

Hi,

For better assistance with your network adapter issue, we suggest contacting Ralink Support. You may ask them for your network adapter's latest driver that will work with Windows 10.

Windows 10 can't see wifi channel 12 or 13

Since the anniversary update it has been impossible to connect to wifi channels 12 or 13. My laptop can't even see the wifi networks that run on those channels.

I'm in the UK. My laptops regions settings are set to UK and UK English. Also in the UK wifi channels 12 and 13 are perfectly legal and Windows 10 should not be blocking them. My wifi adaptor is also compatible with wifi channels 12 and 13

so this is a windows 10 issue.

I cannot find any setting in windows 10 to change the wifi adaptors region.

I cannot find any obvious setting in the registry either.

I have since put Windows 8.1 back on this laptop which now dual boots between Windows 8.1 and 10.

In Windows 8.1 the laptop can see and connect to networks on wifi channel 12 and 13

In Windows 10 it can't.

How can I fix this?

According to the device manager my network adaptor is a Ralink RT5390R

 

Cannot detect wifi channels 12-13 on 2.4Ghz


Hi guys,
I have a strange problem with my laptop Dell m3800 with Windows 10 and Dell dw1560 Wifi mini card with Broadcom 94352 chip.
I am living in Europe but for some reason my wifi card cannot detect channels 12-13 on 2.4Ghz.
I think this is Windows 10 fault because after I fresh install everything it was working on channels 12-13, after I logged into Microsoft account it cannot detect channels 12-13 anymore.

Does anybody know how to fix this?

A little help will be much appreciated.

Thanks in advanced
