LAN Network cable unplugged

By get2ak ·
I have a Compaq Desktop PC with a XP home edition. I have a Linksys Router in my basement connected to the Cable modem. BHN cable connected to the modem, modem to the Linksys Router, Router to 1)Vonage phone 2)Wireless router 3)Desktop Cat5 connection running to the second floor.
My desktop when connected with a Cat5 cable, displays that the Network cable is unplugged. To test this, I connected my Laptop after disabling the wireless connection. The laptop works fine from the same wall connection. Then I took my desktop to the basement. I unplugged the router, wireless router and the cable modem. Restarted them all, starting with my cable modem, router and then the wireless router. Then I plugged the ethernet cable to my desktop and it worked fine. Can anyone tell why it does not work in the second floor? I have both MB connected ethernet adaptor and I bought a Linksys Ethernet adaptor. Both dont work.

Cable Troubleshooting

by HCream In reply to LAN Network cable unplugg ...

1. Distance Limitations: The distance from a node (PC, Print Server, etc) to a hub or switch using RJ-45 cabling running at 10Mbps or 100Mbps is maximum of 100 meters (328 feet). The maximum cable (RJ-45) distance from any node, hub or switch to a switch is 100 meters (328 feet).

2. Coiled cables: Verify that the network cabling isn't coiled or twisted up. Coiled cabling can create electromagnetic fields that may disrupt data transfers between nodes.

3. Avoid interference: Try to keep cables away from power outlets, florescent lighting fixtures, uninterruptable power supplies, and other sources of strong electromagnetic interference.

Finally, since your job is IT related, it may not be a bad idea to invest in a network cable tester kit. It'll pay for itself!

The tester kit is a must. It will save you a ton of time.

Does any network device work on the 2nd floor jack, or is it jus the notebook?

As for cabling. Make sure you do not run it in parallel with power wiring. Ive sen people actually zip tie to power wires.
