Please Help... The problem keeps getting worse....

Same problem here: the wireless work nicely (on a Dell Latitude D630) until it gets disconnected. Then, it prompts for the password, and although it's correct, it's not able to connect anymore. Any help is appreciated, it's quite an annoying bug as the only option it works for me is to reboot.

[voradeaur]

Your problem is rather similar to that of my own... I can reboot the computer with about 10% chance of successful internet connection (also running 11.10.) Those that do not suffer this rather frequent failure (with the dialog box showing disconnected 7 times before quitting) doesnt seem to understand the horror this produces. Its a nicely laid out system I would love to use, however; given this problem... its not looking like a possible answer. I hope you get this figured out for both our sake.. lol

I installed Ubuntu 11.10 on my DELL laptop 2 days ago and I had no problem at all. The wireless detected my home Wifi network and connected as soon as I entered the KEY.

Just to point out the obvious: everything works fine with the wireless, until it disconnects, and it can happen after many hours. Only once it disconnects, it's not able to connect again. Also, upon reboot, it always works fine until the next disconnection.
