I am *amazed* at how much a simple 90 degree bend in a 100bT (or 10bT) can ruin throughput in a cable. Forget it straight-out if you have a kink! If you ever have access to a TDR cable tester, grab a cheap patch cable or long cable or two and try it. Nothing teaches like experimentation! That said, the advice to try uploading and downloading from both ends to the machine in the middle is just plain sage. Cut your problems in half a few times and you'll be within inches of them. - Jy@ On Fri, 18 Aug 2000, Luke Cowell wrote: > I had a NAT firewall setup for my wave connection at home.
