Dell 755 optiplex Nic failing?

Had a Dell that had a solid red light on the network card and a flashing yellow (I think) light as well.

Impending nic failure or problem tracing back to the switch?

My PC is doing the same thing, but I was able to connect to the internet without problems.

Broadcom NIC? Some of their drivers for windows have been flakey.

Other possibility...bum patch cable, bad termination from wall jack..leading back to patch panel. And/or switch that patch panel leads to.

I think so. Not 100 % sure.

The wiring guy and I look at the wiring. He just about flipped out on the way the wall jack was wired (not my doing).

He checked the switches and didn't see any thing out of the ordinary.

I have several of those units. I should check the others "light" activity.

Weird that mine has no green light activity, yet I have no internet problems.

Yeah....link lights are generally accurate...but not always 100% accurate...it's just another piece of hardware that can fail.

I assume you have tried moving the PC in question to a known working location? Tried another network cable? Tried getting the latest drivers from the Dell site?

I have not done anything.

Move the PC to a known working network location and see if it works there. Or take a laptop over to the place in question and hook the network cable up to it and see if it can connect. This should give you a pretty good idea if the problem is cabling or PC/Network card specific.

I assume there is also no network connectivity other than just not able to get to the internet, ie can't access network resources/shares etc.

BTW, there are 2 types of 755's (not sure if the network cards are different between them). One is a normal tower, the other is a smaller/thinner one that can also be laid on a desk where the monitor can go on top of it.
