TIA....Jet I'm getting 1.5 Mb over PPPoE with user space ppp on a 400 MHz Celeron with a crappy RealTek card, so you should certainly not be limited by your hardware. Do you have lots of packet collisions (check with netstat -i)? Perhaps you can try fiddling with the media/mediaopt flags to ifconfig on the interface connected to the DSL box - just in case it autonegotiation is not working at is should. $.02, /Mikko
