Goodness me, thank you for all the replies, I have a lot to try now. One best path may have been via your ethernet and the AT&T 'installed for free' protector.Ĭonnect some other ethernet device to the modem. Once that energy is inside, it will hunt for and damage paths to earth. Did you have sufficient earthing or a 'whole house' protector? If not, then a connection to earth might have been destructively via that ethernet port. Surge damage is directly traceable to human failure. If you did not provide good earthing for the AT&T installed protector, then that AT&T protector might be compromised.

Just one example of why damage might exist. Did your house have a 'whole house' protector in the breaker box? Then a surge could have been seeking earth incoming on AC mains and outgoing via the AT&T 'required to be installled' protector. If a surge existed, then it was seeking earth ground. Power restoration creates damage when myths are invented using feelings. A popular myth, in part, because a surge might have caused the blackout. Device Manager only sees a working brain in the NIC. Your brain can also work even though your ears do not. Either computer's 'ear' or modem's 'ear' hears nothing - is broken.ĭevice Manager is only talking to the NIC's computer. Lights at both ends do not work? Then a connection between computer and modem does not exist. Those lights say same thing for ethernet 'noise'. Your ear has no idea if that noise is words - and does not care. Lights report the lowest layer of talking. Try looking in your BIOS, you might just find something!Ĭlick to expand. I personally know that both LiteOn and Gigabyte had network diagnostics implemented into the BIOS. ID-LPC's are pretty robust when it comes to over/under-voltage, at least in my experienceĪnd yes, there are diagnostic tools. And should you get tired of the adapter, there are often cheap solutions.įact is, even if the circuitry is somewhat fried, it often shows up in the OS anyway. With all respect in the world when it comes to money, a new network card can be both very cheap and very expensive. Bought a new 10/100Mbps PCI card ($15) - worked. Soldered on a new RJ45 port, didn't work. Disassembled the network card => port was completely fried out.

Everything inside the PC worked, but still 'no cable detected' kept showing up. Had the same problem as you a while back.

But just in case, you should try re-installing the drivers if possible. 'En-lieu' with what both Leeky and mailpup mentioned it seems like the port is fried. I can't afford to buy a new NIC card, so any help will be appreciated.Įdit: 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.

It's an onboard 'NVIDIA nForce Networking Controller', and I'm running Windows 7 圆4. 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. 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 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). 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 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). 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'. 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. My computer is plugged into a surge protector, but my modem is not, and I'm using a wired connection. My area experienced a power outage last night during a thunderstorm.
