Recently my desktop was not recognizing Airport Xtreme and therefore not allowing to browse the internet. I ran the default diagnostics and it restored the wireless capability to my desktop ONLY. No peripheral devices can log in. My phone for instance, keeps showing a message: "Obtaining IP address from KHamson Network". After several seconds of trying I then get a message of "disconnected", whereas it immediately then says "scanning" followed by "connecting", and the process repeats itself. What must I do to recover peripheral devices??
