Hey guys, I'm in big trouble. Ive got three macs and have installed 10.7.3 on two of them. Those two can't connect to the internet anymore. I have a TC 3. generation and have just updated it with the latest firmware. On the third mac running 10.7.2 i have updated the Airport Utility and it finds my TC just fine. When i search for my TC on the other two machines AP finds nothing. My best guess is that 10.7.3 is the problem? I have tried updating with the combo update but no luck. I can't access my time machine backups so i can't roll back to 10.7.2 Do you have any suggestions? NB This is the worst error i have ever had on any computer system. Windows have never killed my internet connection by an update. Apple this is just not good enough.
