The wireless on my Airport Extreme n that I purchase last week doesn't work. I have tried doing both hard and soft resets and it doesn't work. The ethernet connections works fine, that's how I'm able to post this, but the wireless doesn't work. On my Powerbook, on my iPhone, none of them show my wireless network. Furthermore, the Airport software is buggy. For example, when I try to configure the wireless, the "Radio Mode" popup menu is blank and doesn't let me select it. Also, when I go into "Wireless Options" where it lets you configure the 5Ghz network name, the "Country" popup is also blank and doesn't do anything when I click on it. I have the latest firmware installed, 7.4.1. I have all software updates installed. So since I tried hard resetting this thing more than once, it still has the same problem. The wireless simply doesn't work. What should I do at this point?
