I've already completed all of the steps listed . I'm running lion 10.7; had connection 2 days ago & now nothing, even with a wired connection. I can't even connect to the wireless network @ work when others can (i.e. coworker running leapord), I havn't changed any of the settings on my laptop? HELP please!!
MacBook Pro (13-inch Late 2011), Mac OS X (10.7.3)
