After updating my 15" Macbook Pro to 10.6.7, I can no longer get DHCP to work on Wireless or Wired! The same is true whether I'm at home or at work... I do use location profiles, but can't see how that would be doing it. When I put in a STATIC IP address, I can get on the network just fine. DHCP just ends up giving me a self-assigned IP. Any ideas?
