I have a 2009 27" iMac and a 24" 2007 iMac with 2 Airport Extreme routers (2013 The latest.

Everything was working perfectly till I upgraded to 10.8.5.

I lost my internet and both routers. Could not use the Internet and Wi-Fi on my iPhone 5.

Reverted to a backup with 10.8.4 and everything is working perfectly as it did before the upgrade.


Does this mean that I will not be able to upgrade to 10.8.5 or 10.9 ??? 

iMac (27-inch Late 2009), OS X Mountain Lion (10.8.4)
