Can someone tell me how to troubleshoot an issue I'm having with my NIC? The card may be completely dead, but I'm not yet convinced of that.
Here's the issue: I have a Dell Studio 1737 Laptop. The network card is not responding to any Ethernet cable that I plug in. I've tried several different cables, 3 different routers, 1 hub. Nothing. No lights when I plug the cable in. The device manager says the device is working properly, and I've uninstalled the NIC and Windows automatically re-installs it. No luck.
Ordinarily I would think that the NIC was dead, but I had this problem before, and then suddenly after a reboot everything started working fine. In both cases this trouble started after I switched from one router to another. Yesterday, I was able to have some success with plugging my computer into one router, but then I would get nothing when plugging it into another. Then it started working again, and now it's dead again.
Does anybody have any idea as to whether there is anything else I can do? As this is a laptop, I believe the NIC is integrated into the motherboard and cannot be replaced. Perhaps I'm wrong?
Any help is appreciated.
