Better would be to: a) Fix or replace the faulty wiring. Just because it _seems_ to be OK at 100 doesn't mean it is. If it's unable to work reliably at a speed it should work at, you need to fix that. b) Force the speed/duplex on both ends. One of the ugliest networking problems I've seen is when the two ends negotiate different speeds or duplexes. It amazes me how few people are familiar with this problem and how to diagnose/fix it. -- Bill Moran Collaborative Fusion Inc.
