Connection problems with the PC?

I have a computer and it often happens that I have no internet connection with the WLAN or the WLAN is released. If I switch the WLAN on and off on the PC, it works again for a few hours. Everything works fine with the cell phone and laptop, I suspect that it is more due to the PC. Unfortunately, I have no idea about this and would like to ask here first if there's a simple solution. I have already tried restarting the router.

A network provider has had massive network problems, at least occasionally, since the beginning of the month. Maybe it's because of that.

But why do I only have these problems on the PC? All my other devices are working fine.
