MacBook Pro, 2.2gHz., 10.5.7
I installed the most recent QT/iT update before leaving the office yesterday, and as a result the internet has died. The hardware is fine, both the airport extreme & ethernet test out fine. However, no access to the internet whether I plug in via ethernet or try wirelessly. Network Diagnostics tells me it's an unknown error and that it can't fix it. Anyone have any suggestions beside putting in the restore disks and starting from scratch?
