Hello all. Just wanted to get some outside imput. That might help me come up with other ideals on what the problem might be. Had computer A plug into a jack in the wall. worked fine. moved computer B there and moved computer A out. But computer B gets a limited connection. Bring computer B to a diffrent jack and it works perfectly. So i grab a laptop and plug into the jack that was giving me the limited error. And got the error. Tried computer C and still the error came up. So I test the cable test fine . test patch cords test fine. I pull a brand new cable (its a short run) punched down with new jack and a diffrent place on the punchdown panel. Thinking this will get rid of the error but no same exact error.

I tested 3 computers on the bad jack to no avail. But all 3 work at diffrent spots on the network. Pulled whole new cable replace jacks and patchcords. Diffrent port on the switch and diffrent spot on the punch down panel. And I still get the same error. Tested both cables and they tested fine. double checked switch settings. and everything looks fine.

I am lost and rack me braine for 6 hours before having to walk away for fear of tearing it out of the wall. Any imput would be great.

Interesting problem..

Did you ever find a solution?

Sounds like it has to do with some kind of interference on that cable. Possibly a near by AC line?

Everything should be wired "straight-through" not "crossover" in this instance...

Hard to say what is wrong...

An interesting thing that I would do in this instance would be to "mirror" the problematic port at the switch to another port. Then, hook up a laptop with wireshark (network sniffer) on the mirrored port. Monitor the traffic and see what you can identify as a problem in the communications between the computer and the DHCP server.

To me it sounds like the speed settings on the port are incorrect, right click the connection on computer A, B and Laptop and click configure, advanced and check for any differences.

Another problem might be MAC Address port locking, occasionally in networks, admins lock down all ports in the network to 1 MAC (physical) address, this stops someone from walking into the room plugging any device in and possibly be up to no good.
