The network I help manage is all Cisco gear, and I have the same trouble at times, so on most of the switches I force 100/Full. Unfortunately, the BEFSR11 has no way to turn off its autonegotiation, and coupled with a dumb auto-sensing switch, that is bad news. However, even after autonegotiation I determine the Linksys to have 100/Full, and I match it on the Linux box with 100/Full, I run into trouble. It is only at 100Mbit that I have this problem. It's as though the Linksys can't properly control the speed mismatch between its WAN (10Mbit/HD) and LAN interfaces when Linux is a client on the LAN side. -- Shawn
