Browser disconnecting/not working on Windows 11 PC

[techmot]

I have been having problems for the past couple of days with my sons gaming PC where, whenever I open any web browser the browser either can't connect and is very slow loading, or the wifi keeps disconnecting despite other devices connecting OK with the router. The browser I normally use is Opera, but it does the same when using Google Chrome and Microsoft Edge. I've rebooted and restarted the computer several times but it still has problems connecting, often the wifi icon on the task bar at the bottom of the screen keeps dropping out or disconnecting where it says there's no internet available, and after I reconnected and loaded the browser up again it the wifi icon either drops out again or the web page or URL I'm loading says there's no internet. The wifi router is working perfectly. Have I got a virus or malware that's causing this, or is it a system problem?.

The specs of the PC are:

Processor: AMD Ryzen 3 3100 4-Core Processor
Installed RAM: 8.00GB
System type: 64-bit operating system

Edition: Windows 11 edition

Maybe the problem lies with the gaming PC's wireless card. If the PC has external antennas you could take a look at them to make sure they are not loose or damaged. If nothing is wrong there, then you could take a look at this troubleshooting guide on Youtube - https://www.youtube.com/watch?v=xWrMpqUuzJI

For testing, you could connect your PC's LAN port via cable to the routers LAN port.
If it's working flawless, then the wireless card is buggy.
If you need the WiFi connection, you could use a cheap wifi repeater and connect your pc via LAN cable to this repeater.

Doubt it would be browser issue but these are all Chromium based browsers which is the case for most of them these days. Use Firefox for trying to diagnose browser issue.

Thanks for that. It doesn't have a external antenna I could see. Since posting I haven't really seen it acting strange, though it does seem to happen at random times.

Yes I as you say it's doubtful it's the browser. Could be a faulty wireless card.

It has nothing to do with CPU, RAM and OS (Windows 11 is 64 bit only)
More of the mainboard - what wireless adapter is installed or if not onboard, then per USB or PCI(e)
Look up what wireless adapter you have in Device manager -> network and look for updated driver

There are several possible reasons why the wireless connection might not be stable. The troubleshooting guide that I linked to is for Windows 10, but Windows 10 and Windows 11 are similar enough that the video is still applicable. The troubleshooting guide's narrator can be difficult to understand. Turning on closed captions may help.

For what it's worth, I never had a problem with the wireless cards in any of my Windows 11 PCs. Recently, I had a problem with one of my Chromecast with Google TV devices. It couldn't stay connected to my wireless network for more than a few minutes at a time. Restarting the device solved the problem. I suspect the DNS buffers just needed flushing.
