This question was asked before, but it went unanswered so I thought I might give it a try and ask.

I have a Lenovo G series laptop which came with Windows 7 64bit. I installed Ubuntu 12.10 recently and I've been having this problem with my wireless signal. I had this problem before, so I had stop using Ubuntu.

I got back into it, did a fresh reinstall of xubuntu 12.10, and still have this problem. When I'm near the router, I have perfect wireless signal. It's at 100% strength. As soon as I enter my room which can't be no more than 20 feet away, I lose signal. I lose my internet. And I can't connect again. I have my drivers up to date and my modem software is up to date too. My modem is one of those wireless modems, which has a built-in router inside. It's a 2wire 2701 series. Although I'm still new to Linux, I'll try and post all the information needed to debug this problem.
