I have a 2009 macbook (polymer case). The airport started cutting out a few weeks ago on me. It turns off and I cannot turn it back on. Initially rebooting would resolve the problem, at least for a half hour or so, but it no longer does. I've tried all the tips on this site: http://osxdaily.com/2009/12/22/mac-...ooting-airport-wireless-problems-on-your-mac/ to no avail. I've also tried changing the port service order so that the airport is first, also to no avail. Any more suggestions?
