Welcome to Seven Forums,

If it was previously working try a System Restore, restore it to a point when it was working.

If that didn't work, remove all wireless profiles stored in your computer, then re-add the SSID or wireless network that you wish to be connected to and make sure that you type in the correct pass-phrase.

An update will be appreciated.

Are you failing to connect to the network you had been connected to?
