Install works fine. Done it with both the install script and the instructions in this set. Distribution is Dapper.

[trubblemaker]

well except for the small issue of your car coming up as eth1 (not really and issue) everything looks great.

Everything looks perfect. It looks so good that I wonder if you have encryption setup on your router. or maybe if you aren't broadcasting your essid. that would make it appear as though it wasn't there but it is....

hope this helps to point you in the correct direction.

If eth1 continues to be your wireless connection you will need to fix your /etc/network/interfaces file fixed.

Did a fresh install of 6.06.1 AMD64 Ubuntu and used the install script in your sig. Really miffed about this . Had it working on a 5.10 version about a year ago and then did a lot of OS swapping on the machine. Goes back and it no longer works :<. Any better chance of having it work on a 6.10 install?

[trubblemaker]

yeah, as I said above your wireless card is comming up under eth1 not wlan0. And don't use

sudo ifup eht1

as you don't have eth1 setup in /etc/network/interfaces, so ifup won't work.
use:

sudo dhclient eth1

if you want it to be wlan0
add

wlan0 driver ndiswrapper

to you /etc/iftab file

 sudo gedit /etc/iftab

[emil0r]

sudo dhclient eth1

looks like your driver is working perfectly, I again suggest that you need to investigate the wireless router settings,

check if encryption is enabled
check for a wireless filter be turned on

to start with it would also be beneficial to broadcast your essid, until you have things up and running properly.

Can you connect to this wireless connection with another system (boot into some other OS if you have dual boot.)


also with wireless you need to set the essid before attempting to get an ip, my bad for not mentioning that

sudo iwlist scan

pick an essid

 
sudo iwconfig eth1 essid <your-essid>
sudo dhclient eth1

[emil0r]

The router has no keys set on the wlan and it's up and running according to the router. I can't check it on any other OS unfortunately.


sudo iwlist scan
