Actually, there's no tested maximum length for CAT5. However if you're going by the specs, 100M is the max between some sort of device. Whether it's a repeater, a hub or something.
Many of use have done networks where we've used CAT5 much longer then 100M for whatever reason, and have had no problem. But, for those of you who have gone through MCSE or Cisco, or any network training, they say the spec is 100M, for performance. The instructor will also tell you after you've learned the spec, and passed the test, forget the spec! In the real world, you do what works. More then 100M of CAT5, works. I think many of us can attest to that. tdh -- -------------------------------------------------------------------- T.
