Comment 38 for bug 348204

I also have the same problem.

I have a Vaio SR220 with Intel Corp. Wireless WiFi Link 5100. I have a Netgear Wireless Router (WGR 614). I get the beacon loss almost every two minutes which results in momentary loss of internet connection. Sometimes (less frequently) the connection loses the authentication and takes longer to connect again. Below is part of kernel.log that reflect both these two problems:
