Solved Rogue network cable Can't connect using switch Tags: LAN Switch Cable Servers Networking Last response: February 27, 2012 9:36 PM in Networking Share krsnendu February 19, 2012 9:16:34 PM Hi, I have an underground cable connecting a classroom to the main server. If I plug any computer directly into the underground cable it connects to the server fine. If I plug a switch into the cable, none of the computers connected to the switch gets an IP address from the server. When I try to assign manual IP addresses I also can't connect. But when I use the same switch and plug it into the server using a shorter cable everything works. What could be the problem? Could it be a cross over vs straight through wiring problem? Any other suggestions?

I have tried using uplink. It made no difference. I also tried using a 4 port switch with wireless. I have a feeling there is something round with the cable. Good enough to work directly to a computer but not through a switch. I used a cable tester and got these results: Lights the lit up.

I'll try to change the plugs. Strange that the computer plugged in directly can handle it but not the switch. krsnendu February 27, 2012 9:36:13 PM Best answer selected by krsnendu.
