WIFI disconnecting/disappearing after Windows update

Hello, I have an interesting problem that I need help solving.

The short of it is that at random times my home WIFI disappears. Like, if you look at the available other networks, it is not there. It would appear again after a few seconds to a few minutes. This happens a few time a day, but sometimes it doesn't happen at all. I tried it on other WIFIs and it doesn't seem to be causing problems, however, I just tried for a few hours, which I don't think would suffice for testing it.

Anyway, I am pretty sure it is a Windows 10 issue, or at least a windows related one, as this issue started occurring after I updated my Windows maybe a month ago. Whenever I had those random disconnects/disappearances my girlfriend had no problems. However, she also started experiencing them after she updated her as well, maybe 2 weeks after. I've spoken to other people and they also have the same issue with their own WIFIs.

I tried digging up solutions, but I couldn't find anything that would resolve the issue. The things I tried so far:
- Making sure that the device doesn't go to sleep/ gets powered off by windows
- Updated my network drivers
- Tried the windows throubleshooting
- Restarting the laptop
- Setting WLAN Auto Config to Automatic
- Making the connection Private
- Disabled Hotspot 2.0

I don't believe that it should be antivirus related issue, as all the people that I asked have different antiviruses, and some don't even have one.

The only other solutions I could find that I haven't tried yet are to reinstall my network adapter, set the WIFI as a metered connection, and reinstall windows.

I am not sure if it would make any difference but my router is Technicolor TG799vn v2. The router itself should actually lose connection as it has an uptime round 5 days and I have experienced the issue several times the day before. I have set the channel to 13 as this one is the least active for my region. And there are just 3 devices connected to it - 2 laptops and a phone.

Let me know if you need more info and if I should try doing some of the things I haven't yet tried.

Happens to mine too, I have AR956x on my laptop. My temporary solution is to turn off wifi > switch to airplane mode > shut down laptop > restart router > turn on pc again > turn off airplane mode > turn on wifi and connect again.

I am facing the same problem. I live in a condominium. My laptop sometimes fails to detect my home wi-fi hardly 1m away whereas it shows ten others within a radius of ~50 meters. I tried restarting the laptop as well as the router without any result. However, at other time it is detected easily.

You need to check what channel your on and what others are on as it's often your on the same one as someone else close so you need to find a clear channel

How do I know the channel frequency? I don't think the router has the capability to broadcast in a different channel than what is already set as default.
