Thinkpad a/b/g/n (AR5418) on X61t is not working well Kubuntu 9.04

can connect, but disconnect in a short while

no such problem under Vista/Win 7 for the same wireless network

anybody has idea?

Thank you

Don't know if this might help, but i had the same issue with regular ubuntu. Using the madwifi drivers solved that...i still have issues making the initial connection (takes a few tries) but once it connects, it stays connected...

KDE tends to make the wlan (eth1 in my case) "invisible" on start up, what I would suggest is that you switch your default network manager.

Because eth0 (Wired connection) can be managed from within the kernel drivers it does not need the gnome network manager running in the background.

What I would do is install Wicd because it tends to work with ALL desktop environments.
It will solve your problem I believe.
The downside to it, that it still has not reached the level that it ID the type of encryption used on the wireless network, so you will have to select it manually.

I hope it helped you,
Also do a search for more network managers, make sure they are Debian-friendly!

I looked it up for you, and Wicd appears to be in the repositories.
simply type: Once its done it will auto switch from the nm-manager to wicd for you.
