Here is a rundown of my equipment: Macbook (2.2 GHz running Leopard) Airport Extreme (just bought yesterday) iPhone (three of them running 3.1.2) HP notebook with Vista (SP1) Motorola Surfboard cable modem (101u model - also bought yesterday) General Issues: Can't see Airport Extreme in Airport Utility Can't connect to main network Can connect to "guest network" wireless on Macbook but not with HP Can connect WIRED with both computers Can't connect with any of the iPhones Yesterday I moved into a new apartment and decided to treat myself to a Airport Extreme and new cable modem. I installed the Airport Utility and followed the instructions for setting up a network. Everything seemed to setup correctly and the Airport Extreme had a green solid light on the front. From my Macbook I can see both the networks (main and guest), but cannot connect to either wirelessly. The error message is a connection timeout. I'm certain that the passwords are correct. I decided to reset all the settings and try again. I was able to reset the Airport Extreme settings using the Airport Utility. Now I still can't connect to the main network, but can connect to the guest network (wirelessly). When I open the Airport Utility it tells me that there are no apple devices seen. This is obviously false as I connected to it currently and this thread will be made while connected to the guest network. Help? Please. EDIT: I wanted to add a picture that showed my Airport Utility. You can see this thread in the background.
