I'm not exactly sure where to post this, but if anyone is familiar with my issue, i'd really appreciate help. Just updated to latest software...then....mac won't connect to wireless network. Other computers and devices do, but not this mac. When I go to another wireless network, it connects fine. The wireless it won't connect to, it does read a wireless signal....but wont' connect...I'm perplexed. Any suggestions? Thanks so much.
