Did you try another encryption algorithm or without encryption? Larry, we talked about the issue on IRC and we decided that it's best if you could take a capture of the whole traffic. So, please set up another card in monitor mode to capture the broken traffic between your card in question and the AP. Best would probably be, if you post an ethereal log somewhere (in private, as you might not want to post your network data here :) ) Thing is, we aren't able to reproduce the issue. I just tried various things with my 4306 card and it works exactly as relieable as under OSX here. We also talked about interference. What type of interference could be possible for you? Microwave ovens? If I put my laptop directly on top of the uwave oven and switch it on, connection is destroyed. But it recovers immediately, if I move away from the thing or switch it off. Maybe there's some older oven somewhere? Or some other device transmitting in the 2.4G band? Did you try to switch to a different channel? Be aware of adjacent channel interference, too. So, if you're currently on channel 1, try to switch to channel 13. You could probably also try to play with the interference mitigation code, which is provided by the driver. We are not sure if it works correctly, but it's worth a try. The interference mitigation mode can be selected through the bcm43xx sysfs attributes. It defaults to OFF. See file bcm43xx_sysfs.c for details on possible modes. Well, finally, I would like to look at some ethereal logs of the whole thing.

So, if you're currently on channel 1, try to switch to channel 13. I don't think it is interference. There are two other AP's that I can detect with iwlist s. I'm on channel 1, and the other two are on channels 6 and 11. This should be the ideal case. I don't have any other 2.4 GHz equipment, and the microwave was off. I am in the US and cannot use ch. 13.
