Upgraded to 11.10: Wifi Doesn't Work

[benedictusk]

Hi.

I recently upgraded to Ubuntu 11.10 from 11.04 on my laptop, and now it can't connect to wifi. I have tried connecting to my house's wifi and to my school's wifi, and neither of them work. They worked fine before the upgrade.
When I select an available connection, I enter its password, and then it says "connecting..." but never connects.
Might anyone know the problem? Is there any other info I should provide?

Thanks!

check to see if there is additional drivers one could be for you wireless, I noticed for myself any how the bare bones driver for wireless thought it worked signal was very weak and would lose the connection a lot making it seem like it wasn't working ..

as soon as I installed the wireless driver in addtional software things were good as the y shouild be ..
