I think I know the answer to this question, I’m just here whining……
I ran a simple 75 foot CAT5 data run, punched it down to a Leviton CAT5 module on each end, using 568A pair sequence, and it just does not work.
Got link light on both ends, but Windows XP status shows packets sent, but no packets received. So DHCP won’t work, obviously and neither does PING or anything else.
Open pair, right?
I hooked up my Test-UM LanRover cable tester, it shows PASS and the capacitance measurement is normal. I double checked it with the cable tester, even trying to wiggle the cables in case it is a bad connection. Nope. This cable is perfect.
So my cable tester shows that it’s good, from end-to-end, including the patch cables. Tried swapping patch cables, of course.
I get link light at both ends, have tested NIC and swapped ethernet router at other end.
The PC can ping a device on a switch attached directly to the PC, but not the router on the other end, which is pingable. Of course the PC cannot get a DHCP address either.
I plan to just re-terminate the CAT5 jacks….maybe something is not punched down cleanly???
This is a standard 192.168.0.1 network, so I doubt I did anything stupid. Windows firewall is turned off, very plain-jane PC (security DVR).
If all else fails, I pulled a second run of CAT5 cable at the same time, so maybe there is cable damage from installing the cable???
I know, I know, I should have used wireless LAN!
