I'm running an iMac, and a Macbook Pro 13" (iMac - Leopard, Macbook Pro 13" - Snow Leopard). My internet setup is an At&t 2-Wire 2701hg. I am able to connect the iMac through airport, but my MBP is unable to connect because it says under the network tab that it has a self-assigned IP address. I have tried taking off the firewall (it is currently off), resetting the router, and deleting my prefs from the Library (which by the way I couldn't find the one for airport). Hoping to get this thing up and running, and I appreciate any assistance.
