trendnet tew-643pi wireless-n card not working


Hi Linux community!

I am running Ubuntu 8.10 and just installed the wireless pci card above. I first installed the card and driver in XP...it works fine.

In Ubuntu, I installed the driver with ndiswrapper. The card is being recognized and is seeing my wireless network, but it's not connecting after I enter my WEP key. Here is some terminal output...

Code:
 ifconfig

To show that it's seeing my wireless network...

Code:
 sudo iwlist scan
[sudo] password for chase: 
lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

Any help would be much appreciated! I don't see what the problem is...I'm able to see the network...is it the WEP key/protocol maybe?

update

just an update here...

i disabled WEP and was able to connect. This should mean that the problem is isolated to WEP or something in the configuration. Unfortunately, I don't know enough to alter the configuration file. I'm used to just installing a device and driver, and having it work. Any help is much appreciated.

Wink connected? yes!

Since this is getting some views, I'll post my solution here:

1. I uninstalled Network-manager-gnome.
2. I installed Wicd using the instructions on http://sourceforge.net/download.php
3. After trying my WEP key, resetting everything in sight, and trying again with a new key...still no connection.
4. Enabled WPA encryption on my router -> reset.
5. Configured Wicd with WPA and my new key... now have strong connection.

Long story short, use WPA.
