Hello, I am using the latest beta build of Tofu, and have had this problem for quite some time. My router is a v4, and is located in the room next to me. I connect to it via Windows, rather than the Linksys product. It disconnects and I get bad signal connection. I only get around 2-4 bars and speed is 2-11mbps (signal strength is mostly "low"). I know I should be getting at least 54mpbs because I have in the past. Please help. Thanks.
