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, an= d rebooted the laptop. Checked that the router was using 2.4 for the laptop. Still hu= ng the router! What I've done temporarily is change the unlimited return value from 0 to 4= 000. 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
