247840 2004-06-27 04:37:00 Thanks. If you were buying it would you just get category 6 and be done with it? Or is it really just of no benefit compared to the 5 in my situation? Mcpisik (4924)
247841 2004-06-27 04:43:00 It won't work. :D

There are two pairs used. One is "transmit", the other is receive". The T end at one device has to go to R on the other and vice versa.

Because the Ethernet designers live in the real world, there is enough protection in tranceivers to stand a lot of abuse. (There's even a spark gap ;-)). But connecting T-T and R-R just doesn't work. (Except for some clever gear which autodetects and can cope).

The ports on a switch, hub, or router are wired one way, the ports on computers are the other so that all the connections in a network can be straight through. This helps to reduce the confusion. One port on a R/H/S might be marked "X", or have a slide switch beside it. This is for expansion (so a straight cable can be used from this to connect to another S/H/R). Plugging a computer into an X port won't work either. ;-)

some network cards can autodetect crossover cables and use them as normal cables (afaik).

Just out of interest check the ports on your router or the manual for such words as auto sensing o (up)link (which are usually auto sensing AFAIK) . I think more often than not a modem/router with a hub will just have one uplink port for connecting other devices to like switches, wireless, etc .
