I have a compaq workstation that cannot see the network. At first, I thought it was the patchcord, but I hooked up my laptop and it worked fine. I have checked and rechecked the network settings and everything ok. Still can't see network on compaq. I pull the workstation and hooked it up direct to hub. At this point it sees the network. I bring it back to that original port and it still doesn't see the network...

I have a dialup connection for this computer. No hits in device mgr, nic works fine.

Try replacing the NIC with a known good one. Try using a known good workstation at that location. I would take that work station to a known good network location if it still can not connect, even after reinstalling hardware and software. I would format and reinstall the O/S and try a second time, if it still dont work. I would set the computer in the spare parts bin. And set up another computer for the user.

I have used another computer and it works. The compaq is on loan from another company.

unfortunately, I don't have the original software. The computer is on loan. I cannot reload the software.

You may need a crossover cable so your send and receive signals don't collide. The hub may already be configured with a built-in crossover.

Hi,

My guess will be either faulty wiring - use a cable tester to verify the connections are solid.

Or... A faulty or badly made nic and/or drivers - the one in your laptop is more tolerant than the workstation.

Or... And this is unlikely... the length of the cable between the patch panel and the PC is too great and its out of spec.

I'd be faily confident its a hardware problem - although it could be the nic/driver combo.

Cheers,
Tim.

I have run a tester on the cable. It's fine. The cable runs fm pc to hub. I can't find a updated driver for dec 21143 nic. THe computer isn't ours...Maybe I should just return it!

If the same box hooked directly to the hub works but doesn't at the patch cable, I would check my connection between the hub and the patch port. How old is the network? Is everything CAT 5? I have seen a laptop work on a CAT 3 cable and a full blownPC not. I've seen 2 different PC where one worked and the other didn't. It just depends on the NIC and how strong it is but in both instances I ran in to what was supposedly CAT 5 and I'm betting it was actually CAT 3. Only solution was to replace the cable from the hub to the patch with CAT 5.

I have had our electricians out and recheck the wiring termination. At first they discovered it wasn't correct. They corrected it but it still doesn't work. The wire is a cat5, the wiring was done this past summer.

probably the keystone block at the port you are plugging into. Assuming it was once working as it is currently set up. Lan tester is the right idea. do you get a link light at the hub when you plug into the port? Has there been any new electricalwork done in that area?

by mikepell

i get a link with another workstation at the same location. I have had the wiring company come back in and check out the wiring. ok but still no link w/original computer.
