Slow/no Internet, lagging ping, network adapter issue?

[callllllum]

Hi all,

New here, but have an issue on my wife's gaming PC I just can't solve.

PC runs fine, connects to the wifi fine (previously it didn't, it would say "Connected, no internet", but I reinstalled the device) but it either doesn't load any web pages, or takes a long time to run at all. I've tried pinging various sites and using an online speed test, but the ping time is 1500ms+. I've flushed the DNS which did seem to help, but it's still very laggy. Other PC's are nearby and don't have the issue, nor do phones/tablets. I'm struggling to work out what the issue is. There are no other progs running in the background either, though I do see a CPU spike sometimes but I don't think that can be the issue.

It's got an intel dual band ac 3168 card. Is it work installing a new adapter? I'm certain it's not the wifi/router as we've moved house recently and still have the issue.

Open to any advice/ideas. Thanks in advance

Callum

Do you have any other devices on the same network with similar issues?

Nope, no other issues with any other computers. I have my work PC set up next to it, technically further from the hub, and that has no issue.

I suspect the network card could have become defective. An USB wireless adapter are cheap these days, so I would suggest getting one and then disable the one in the computer and see if the new one has the same issue.
