Probably. I was commenting on the (relatively) high collision count I'm
seeing. This is a hub (DSL router) with 2 PC's on it. I have never seen this
many collisions happening before. Plus I can no longer transfer files from the
Windows system to the FreeBSD system (even using FTP), something that worked
flawlessly at least until October 17th. So something is broken. You think it
could be hardware?

Thanks,
Jos
