Network cable is being seen as unplugged

[Parrey]

I have just rehooked a computer back up to find that the network cable is not being detected and the lights near the ethernet port are not on either

i know its not the cable because the cable works with other comps (e.g the one i'm on now)

i know its not the router because i'm on it now

and i'm pretty sure its not the onboard lan because its being detected in my devices

so any help

Remove it from the devices, reboot. Check then. Are there any lights near it that come on when you plug it in?

Try uninstalling your onboard ethernet adapter from your device manager, and reboot your computer.

Now reinstall the drivers.

And if the excellent advice above does no good replace the cable...they do go bad.

If the cable works, then you might have a problem with your network jack.

The missing lights on you NIC are a sure sign of hardware failure somewhere. This means the cable is not trasmitting, which could be caused by an improper connection (bad cable, bad network card) or a missing link somewhere (messed up hub, router or modem). But either way you go, its hardware for sure.

The router should have a reset button, try resetting it.
