I have a black MacBook running 10.5.8, and it's been having airport problems. When browsing the web, I'll start loading a page, but the blue progress bar goes nowhere. I've noticed, however, that if I click the airport icon and rollover the name of the wireless network I'm on, the page loads normally. I don't believe this is a software issue as I've replaced the HD and it still happens. I also have no Bluetooth capability; system profiler just says 'not available'. Bluetooth and airport are the same module IIRC. The apple hardware test showed nothing wrong... What can I do? Are there any other testing utilities to check the airport? This doesn't happen every time, sometimes it works with no trouble. Any help is appreciated.
