Thanks for info/testing. I still wonder how driver's code can cause any disconnections happening exactly every 5 minutes... Any idea anyone? One bug that was recently discovered and that sits in b43's code is passive scanning. For some reason it seems b43 doesn't do passive scanning, I didn't have time to debug that yet. I wonder if this can affect connection stability anyhow. Perhaps you could try performing manual scanning every ~minute? It's really just a crazy guess, I don't have any idea why it could help. But it's so trivial you may want to give it a try. -- Rafał -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
