Its not pretty, it requires you spend a few bucks, but it seems to work. I did some searching on a WiFi USB adapter for the iMac, and found the Zonet ZEW2500P. http://www.newegg.com/Product/Product.aspx?Item=N82E16833130111&Tpk=Zonet ZEW2500P Also available from Amazon. I plugged it in, got the drivers from: http://www.ralinktech.com/ralink/Home/Support/Macintosh.html (Second link is the 2500) It installs just fine, you have to use their stupid Wireless Utility... BUT... No more lockups in WoW or otherwise (So far, I will continue testing, and if it proves to somehow NOT fix the problem, I will report back). No Ethernet Cable connected, WoW has lasted longer than I have ever had it last while on WiFi. So yeah, its not pretty, it costs money, we shouldn't HAVE to do this, I know that, doesn't have to be said again. But if you are waiting on Apple's fix and NEED WiFi, then this so far works.
