My area experienced a power outage last night during a thunderstorm. My computer is plugged into a surge protector, but my modem is not, and I'm using a wired connection. When I got home from work, I discovered that not only did the power outage knock out my internet service (something on the ISP side) but it also did something to my ethernet port.
I can see the device in the BIOS, and in the Device Manager, and also in Network Connections, but no matter what I plug into it, it just says "network cable unplugged". I definitely have a cable plugged into it and into my modem (which is on and working, just not connecting to the internet), and I know that the cable is fine (I tested it for continuity, and I tried a different cable). When I plug something in, the lights that normally indicate activity (or at least the existence of a cable) don't light up, so I'm a little worried.
I realize that a surge from the power coming back on might very well have fried the circuitry, but I'm confused because (knock on wood) nothing else appears to be damaged in my computer, and the modem itself appears perfectly fine (with the exception that it won't connect to the internet which, like I said, is due to a problem with AT&T's lines). Is there some diagnostic that I can run or something I can do to verify the integrity of the ethernet port? If I look at the motherboard itself, would it be possible to see any potential damage?
I would think that if the circuit was fried, it wouldn't show up at all, but it's there, it even has the name and everything. It's an onboard "NVIDIA nForce Networking Controller", and I'm running Windows 7 x64.
I can't afford to buy a new NIC card, so any help will be appreciated.
Edit: I should also add that I plugged a USB wireless adapter into my computer and it worked fine, connected to the modem (which is a wireless router as well) just fine and I tested it by also connecting my Xbox wirelessly and streaming music, worked perfectly.
