I'm brand new to Ubuntu Linux. Am unable to connect to the Internet with FireFox. I am running from a Gateway m520 and am using a wireless connection to a Comcast Cable network. In order to turn on connectivity The laptop uses Fn-F2 key in the Microsoft Windows arena. However, in Ubuntu the keys don't work. I'm not sure if this is the problem or there is something else involved.
Sorry about the lack of know-how. Hope someone out there might have a suggestion.
