Only a single 100 meters, if I recall correctly. Or approximately 300
feet. I looked into it once for my factory. That goes all the way from
the front office to the back of my factory just fine.
It's actually 100 meters between switches or hubs, but only 2 hubs
maximum for any path traversal. So check if you have only hubs in your
house and count how many your signal is going through.
The limits are more relaxed for 10baseT, I think 4 or 5 hubs, so if 10
works and 100 doesn't, check how many hubs you're sending your signal
through. If it's more than 2, replace the central one with a switch if
possible. That's a better solution than putting up with 10baseT (or
replacing wire already in the wall).
Is the wire in the wall CAT5? If not, it's not rated for 100BaseT
anyways.
also that 100 meters assumes no crosstalk or interference from
flourescent light ballasts, microwave ovens, televisions, other cables
carrying electricity, &c... It's maybe not such a real world number.
I'm inclined to distrust cables, I just lost a day last week to finding
out that the reel-up cable in my bag, while perfectly able to pass mail,
web, and IM traffic, was unable to allow tftp through to a router I was
configuring. Replaced the cable, all was fine, reelup cable went in the
round file.
