I'm not sure how to check my laptop's duplex, here's what is on my
gateway:

philip@wombat:~% ifconfig -au
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 207.202.235.154 netmask 0xffffff00 broadcast 207.202.235.255
        inet6 fe80::210:5aff:fe10:b021%xl0 prefixlen 64 scopeid 0x1
        ether 00:10:5a:10:b0:21
        media: autoselect (100baseTX <full-duplex>) status: active
        supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback>
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 10.2.0.1 netmask 0xffffff00 broadcast 10.2.0.255
        inet6 fe80::250:baff:fed1:b12c%rl0 prefixlen 64 scopeid 0x2
        ether 00:50:ba:d1:b1:2c
        media: autoselect (none) status: active
        supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback>
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x9
        inet6 ::1 prefixlen 128
        inet 127.0.0.1 netmask 0xff000000


However, if it was a duplex problem wouldn't I see that when transfering
from my laptop to the gateway and from the net to my laptop (which I can
get about 80kb/s)???
