Hi there,

Just did a clean install of 12.04 on a brand new Lenovo notebook. During the install I was unable to connect to my wifi, so just ignored and continued. Once the install was complete I clicked on the wifi symbol from the desktop, but couldn't see any networks. I tried connecting to a hidden network using SSID of my local wifi, and seemed to connect after requesting credentials.

I fired up Firefox and actually managed to hit the Firefox/Ubuntu start page, but then I saw the network disconnect, and after a few seconds it asked me for the wifi password again. That's the last I've seen of Internet connectivity! FWIW, I also don't seem to have a wired connection?

To my (uneducated) eyes this seems to be an issue between Ubuntu and my wireless router, but I don't really know where to begin tbh! Appreciate any and all suggestions.

Many thanks.
