Comment 2 for bug 354548

I have experience the same problem on Ubuntu 9.04 beta on Dell 1420 with Gigabyte GN-WI06N-RH (same chipset ,see link below) using wpa2.

What I have discovered (as far as I can tell) is that when you create the network profile it gets "Pre-Populated" with a wireless key other than the one you gave it. So in essence what appears to happen when you create a wireless network connection the key you give gets "appended" to the end of the pre-populated key as if you were in Bash and used >> command to append the key, so it really has 2 keys back to back in the key field, so it fails. If you create the connection and then go back and change the key to the correct key it work's ( at least for me), although it doesn't report the speed of the connection accurately, it has thus far worked flawlessly...

Bottom line athk9 works great with wpa2 AES except I cant get accurate network speed info.

Card I am using...

I would give you more info (ie dmesg) , but I am using a different machine as I write this. Please let me know if more info is needed..
