It looks like this patch works around some kind of bug without really fixing it. What's going so wrong that it takes a firmware reset to fix it? I'm pretty sure Windows doesn't have any problems. These problems can happen within seconds of associating on Linux. (For reference, I have a Lenovo X200s that is barely usable at work with 802.11n enabled on Linux but works just fine on Windows. A coworker's T61 has the same problem, and he's also running Linux on a different NIC (5300 or 4965 I think -- I don't remember exactly). --Andy -- 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
