Cabling Question

Nov 1, 2004 10:02PM PST

I recently attempted to network a home running cat 5. I have done this before in apartments but never in a house. I was running cabling for a second floor bedroom to the router that is located in the 1st floor living room. For some reason I can't get the connection to work properly. I have a line tester and all wires test fine. But when I tried to connect the PC to the router, NOTHING! I tried different NIC's but still no luck. Is there a different type of cat5 I need for longer runs? If the cat 5 cable is next to a electrical cable could there be interference? But if that was the case then why does my tester show both ends working fine? PLEASE HELP!!!

Since you can go 100 meters with CAT5, that's rarely an issue. In fact I've gone double that from a switch to another switch in a single run.

My bet is your wiring pairs are incorrect.

i would think the same only my tester shows everything is ok. My tester is works as follows:

My tester has two components. The main unit plugs into one end and another unit, a receiver with 4 lights representing the 4 pairs, plugs into the other. The main unit sends a signal and the receiving unit lights each of the lights individually, green for good red for bad.

All lights show green showing all should work fine. I just don't get it.....

Most testers do not test for correct pairs. Only that continuity is proper.

The pairs are NOT 1-2, 2-3, 3-4, 5-6, and 7-8 but I see that all the time.

I tend to agree with Bob, but I would try running another cable(known good) to rule out a bad NIC or port on the router. Try to get it working on a shorter run then go for the home run.
