The athlon is using a 3com 905b I believe, and the PII is using an intel fxp type card. Granted this is from my living room to my bedroom so that may be part of what I see. Also, the Dual PII is running -STABLE as of a week ago, and the Athlon is running -CURRENT as of about a week ago. Ken On Fri, 30 Nov 2001, James C.
