I was on my laptop dell latitude d630(wireless was working just fine) then out of no where it stopped working but if use a wireless usb adapter i can reconnect i have tried sudo get-apt install firmware-b43-installer and i tried purging the bwml(something), i have rebooted removed the adapter and im still not able to connect to the wireless, i can see all the available networks but it wont let me connect to any, i have passwords for all of them, but when it times out it prompts me to enter the wireless password again and then repeats the same problem.
I, too, have A Dell Latitude D630, running Ubuntu 11.10, and connect to my local Access Point (WPA2-PSK) with ease, and have connected to an Open (no security) AP.
Click on the Wireless icon in the top row of the screen, make sure that Enable Networking and "Enable Wireless" are checked; then select "Edit Connections". Click the "Wireless" tab. For each connection listed, select it, click "Edit". In the window that opens, click the "Wireless Security" tab and ensure that the "Security" is set to the "right" value for that connection, and that the "Password" is correct (You can click on the "Show password" box to see the password).
