Extending a crossover cable

Hi All,
I currently use a long crossover cable (CAT5 UTP, male RJ45 to male RJ45) to
network a pair of PCs. I need to move one of the PCs and the current cable
is no longer long enough. What cable/adaptor should I use? Can I add a
normal (ie non-crossover) male RJ45-RJ45 cable plus a female-female adaptor
in order for it to still behave as one long crossover cable?

Cheers,
S.

Yes, but the extra connections may cause problems with the signal-to-
noise ratio. Worth a try though, as long crossover cables seem to be a
fair bit more expensive than regular patch cables.

Will try,
cheers,

Normal straight patch cable and normal extension adaptor ie pin 1 to
pin 1 .... pin 8 to pin 8 (unless you buy it from maplin who seem
call it a crossover adaptor)

No more "extra connections" than a normal hardwired + wall sockets
arangement, unless in working in an area with a lot of stray
electromagnetic inteference signal to noise ratio isn't a problem with
100baseT networks.
When considering length of cable the main factor to consider is that
the maximun length dosen't exceed that which will cause timing problems
, unlikely even on the bigest home network.

That's true, but that arrangement uses solid core cable for the long run,
and may even have been carefully routed to avoid interference sources and
sharp bends/trample damage :-)

I've heard that even running too close to a fluorescent light can
cause problems.

Indeed.
