I have a broadband modem from my cable company connected to a Netgear wireless router. This setup has worked flawlessly for me for the last couple of years until the last week or so. Now, I get disconnected from the internet every 2-5 hours. Doing a hard reset of the modem and/or router (I've done them individually and in concert), or resetting the network adapter doesn't fix the problem. When I do any of those things, the computer cannot 'see' the existing network. Instead, it just says it's connected to an 'Unidentified Network', but the adapter itself isn't sending/receiving packets. If I reset the computer, it usually fixes it, but didn't this morning.
The wireless router's setup is incredibly basic. No port forwarding enabled or anything. I've run scans with MSE and Malwarebytes, but nothing popped up. The problems seem to coincide with me installing Windows Updates, so I've restored my system.
It's a Windows 7 PC, if that makes a difference.
If this problem pops up again, what should I do? The kid at my cable company's tech support line tried telling me it was a power surge issue, but I've never had a power surge issue before in this house and with this equipment, so I'm not buying it. To me, the symptoms make me believe the Netgear has an issue, given everything is funneled through it, and when the problem occurs, it's no longer visible to the computer.
