I've dealt with these cards too, and what I've found is that the card often won't properly autoprobe the Ethernet hub. It's common for the card to go into 10Mbt, full duplex with an older Ethernet hub that will only support half-duplex. Unfortunately the instructions for switching the mode on the Realtek are not clear, and read literally they don't work. Here's what does: ifconfig rl0 media 10BaseT/UTP 10BaseT, half duplex ifconfig rl0 media 100baseTX 100BaseT, half duplex ifconfig rl0 mediaopt full-duplex either speed, full duplex. (run this after setting one of the first ones) Ted Mittelstaedt tedm@toybox.placo.com Author of: The FreeBSD Corporate Networker's Guide Book website: http://www.freebsd-corp-net-guide.com >-----Original Message----- >From: owner-freebsd-questions@FreeBSD.ORG >[mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of Mark Sergeant >Sent: Thursday, April 05, 2001 11:14 PM >To: Richard Lucas; Aaron Hill >Cc: freebsd-questions@FreeBSD.ORG >Subject: Re: FreeBSD limiting bandwith? > > >No it is the Realtek card, some of the cards have xtreme issues >under FreeBSD, >I know this as I have one on my laptop, works great at 100baseTX but at >10baseT/UTP I am lucky to get 80k/sec before this I was getting 1-2k/sec in >between machines.
