Well, the obvious first step is to reinstall your Wi-Fi card drivers.
The less obvious second step is to get rid of Norton, because seriously? Norton?
Third, you might try CrowdInspect- it's a free process scanner. I bring it up because it doesn't just look at what's running on your machine, but also what connections said processes are making. Might tell you more about what's going on.
Fourth, consider picking up a cheap USB Wi-Fi stick. If that works (and the one in the machine doesn't), you now have a workaround... and an indication that there's something hinky with your internal card. If you've already reinstalled/updated the drivers for it, you can reasonably infer that the drivers aren't the problem... and if it's not the drivers, it's probably the hardware.
Also, try a virus scan. Multiple scans, with multiple free programs. Norton has a bad habit of missing things, and not cleaning up what it detects. Oh, and make one of the free ones you use Malwarebytes; it does better with the malware than most. I'd recommend keeping it and one other free AV- maybe Avast- when you finish, in place of Norton.
There's also HijackThis, which'll let you see what's running on the system, and remove the registry entries that make it happen. Stuff that starts at startup, browser add-ons- the works. BE CAREFUL, though- it's quite possible to screw things up with this one.
tl;dr: You either have a software problem, or a problem with the Wi-Fi on the machine. Check your processes, scan for viruses/malware, and get rid of Norton on the software side. Update drivers, check your connections, and try a different Wi-Fi device on the Wi-Fi side.
I *suspect* it's a driver issue, but I don't know for sure from here.
