Intel 4965 wireless, Linux, and Afterburners

Important note if you have Intel 4965 wireless (the card used in the Dell XPS m1330, for example) - the Linux drivers for this card do not work well with "Afterburner" mode in Linksys routers. I assume it's the same for "Super-G" and modes from other brands. Turn off that feature and you may save yourself hours of trouble.
