Wire pairs in UTP cable are twisted in order to eliminate interference and noise.
The correct cable wiring is the way it is so that the two send wires are on one twisted pair, and the two receive wires are on another twisted pair. In a cable wired the "not mixed up" way, the two receive wires will be in different twisted pairs. So when the signal tries to get across wires in different twisted pairs, it loses integrity. That is probably why the router didn't like the cable.

My cable tester showed all 8 wires connected & in sequence, but there was no connection between the router & the PC. On inspecting the connections, I saw that the "trou de cul" who had done the original install had 1 pair going to 1&2, next pair to 3&4, then 5&6 & 6&7, which is not standard! I re-did the connectors, in the correct sequence, & everything was fine. My question: if all the wires are there & not mixed up (1-1, 2-2, etc), how come the router had a problem, & how come my $150 (more than the router!) tester didn't find the fault? Note that a cross-over cable worked OK, & the installed cables are straight-thru. I guess I'll give back the tester - another shop has them for $35!
