View Full Version : [ubuntu] Can't connect to secure wireless network

July 1st, 2009, 05:15 PM
Ok, I have a Broadcom BCM4318 wireless card in my laptop, and i just managed to install drivers with ndiswrapper.

I can connect to a public, unencrypted wifi network, but i am finding myself unable to connect to my own, encrypted, wireless network.

The security mode is "WPA/WPA2-Personal(PSK)" and the Authentication is "WPA-PSK + WPA2-PSK"

Encryption technique "TKIP+AES"

The network broadcasts on 11b+g+n so i dont think it is a network compatibility issue.

In the networks window, the PSK is changed from what i set it to, to some sort of hash, no matter how many times i set it back.

Any advice anyone?

Edit: both baubles in the connecting icon turn green

I had a similar problem with my Broadcom card. I'd guess it's because the Windows wireless drivers for those that are posted in all guides are so old that they don't really support WPA or WPA2.

Anyway, to circumvent the issue I just went back to b43 instead and now it works just fine.

Please try the Ubuntu Wireless Troubleshooting Guide (https://help.ubuntu.com/community/WifiDocs/WirelessTroubleShootingGuide). I use zd1211rw on my card.
