To make a long story short, I updated my MBP to 10.6.4 last night and now the wifi doesn't connect to the internet. It can see the wireless network and connect to it, but it wont allow me internet access. I'm currently in a hotel, as Im on a business trip, so I really need internet access. Is there a way I can go back to 10.6.3? Everything was working fine until I did the update. My iPad(non-3G) still connects to the internet just fine... Any ideas??
