[AMD Official Use Only - Internal Distribution Only] I tested Kalle's patch. Laptop connects via 5GHz band by default. Comcast router still crashed in a hurry. I blocked (via NM.conf) the 5GHz mac of the router, and rebooted the laptop. Checked that the router was using 2.4 for the laptop. Still hung the router! What I've done temporarily is change the unlimited return value from 0 to 4000. Somewhere around 5325 the Comcast router gets cranky/weird, and at 5350 it is resetting the wifi stack (without resetting the entire router). So there's no boot time flag to turn the feature off currently? Jason
