Hopefully this is the right area to ask!
So I've been having computer issues on and off for about a year, mostly down to something windows related when it comes to refusing to boot after restarts. Fingers crossed I think the latest format/fresh installation seems to have fixed it. But one problem which has been a constant for awhile now has been my wireless connection dropping.
I know very little about this stuff, so apologies for the lay explanation. Basically I have a set up with a router in another room which my PC is connected to via a wireless card. I have a feeling the wireless card itself may be the issue as it is probably 5yrs old. But then again, I don't know if them aging is a particular problem? I get constant internet disconnections on my PC. Over a 24hr period I'd say it would happen maybe 7-8 times. Each time it happens it'll stay disconnected and the wireless symbol on the taskbar has the red symbol over it. To fix it, all I do is right click and trouble shoot. It immediately fixes it and gives the message "a network cable is not properly plugged in or may be broken" as the detected problem, then fixed is "problem with wireless adapter or access point". I'm not really sure what that means ... it seems to be suggesting a hardware issue but then without touching anything hardware related it can be temporarily fixed just through this method.
I don't think the problem lies with the router as it is reasonably new and is working when my PC isn't (i.e. my phone is still using wireless and laptop too). So the problem has to be with my PC. But I don't know if its as simple as needing a wireless card replaced?
Is there any other diagnostic stuff I can run to check this?
