what replacement wifi card do i need for iMac 21.5-inch EMC 2308 late 2009 model
Need to replace wifi card. For the life of me, I can't find the exact model # of wifi card I will need. Only that I need "AirPort Extreme (802.11g/n)," but when I search for that, I get all sorts of different shaped and sized cards that meet those specs.
