At one point I was desperate and used some cat3 keystones with cat5 cabling worked fine for some of the short runs I did but one of the runs was almost 100ft and I had to force the network card into 10mbit mode to be able to get any communication going through that link (it would auto neg at 100 but I could get and data through). 6mo later we replaced the computer and couldn't get data com going on the new computer for a long while until I finally remembered that I had used the cat3 keystones and replaced them and things was working again. A Pain in the rear will never do that again. Might be able to make it work NOW but later when equipment is replaced and it isn't working will you remember what you don't and get it working quickly again? Not worth considering in the long run if you ask me.

My question was: Can anyone show me reliable equipment that will do 100Mbps+ on cat 3? Not according to this: http://en.wikipedia.org/wiki/Category_3_cable or my experience. If such an animal exists, I could use it, which is why I asked. We may be in game of semantics here. Can you get 100Mbps? I suppose a short cable on the bench might do it but not in the field reliably. In my experience, in order to get a reliable connection over cat 3, I had to lock down the switch ports to 10Mbps. I would never claim to know it all but I've been around the block a time or two. The windings are to cancel out EMF which can cause errors that affect speed due to transmission retries. The speed capability of a cable is due to the quality of its wire rating - http://en.wikipedia.org/wiki/Category_5_cable and http://en.wikipedia.org/wiki/Category_6_cable Obviously, by utilizing more that 2 pair, you can do some interesting things. -RickG On Wed, Nov 18, 2009 at 12:58 AM, Robert West <robert.w...@just-micro.com>wrote: > Phone line is twisted pair and normally 2 pair.
