Good evening sluggers,

I finally got around to installing ubuntu on my new laptop (Presario r4000,
Athlon 64, Ati radion 200m, yada, yada, yada). After a little tweaking got
the video working and everything else works great with one exception, the
wireless card. It is a broadcom based 802.11b/g chipset. I followed the
setup instructions I found at this wiki:

https://wiki.ubuntu.com/HowToSetUpNdiswrapper

and everthing seems to be workingbut I can never pull a dhcp address. Here
is the output of the ifup wlan0 command:

for comparison, here is the output of the same command with the wired eth0

The wireless tool in KDE sees the ssid and has perfect signal strength. Ii
can see the iiinterface and ifconfig shows an ipv6 address but I just can't
seem too pull a DHCP address.

Does anybody have any ideas?

thanks in advance,

Keith
