I am very new to the Ubuntu Operating System and Linux overall. But I have recently acquired a Acer Aspire 4339-2618 that has Ubuntu Linux 12.04.1 installed as an operating system. This computer happens to have a problem where if you step about 15 feet away from the router you get disconnected from the internet/network. I have attempted to re-install Ubuntu and just change the router completely but that did not work at all. So if anyone can give me some help it would be GREATLY appreciated.

Thank you for your assistance!
