I have an "n"Airport Extreme and it is dropping signal intermittently. It goes away for about 15 minutes to 1/2 hour. It does it almost every night. Sometimes when the signal is not dropping, the strength of the signal is ridiculously low. I have two mac laptops, one is "n" technology enabled, one is not and I have an iPhone. All show how the Airport drops the signal or the weakness of it. I thought it was my ISP, but I bypassed the Airport by connecting to the DSL modem and internet worked just fine. I plugged back the Airport and signal would be lost again. Any Ideas? I am going "n"uts.
