What's the matter with apple and WIFI?
My first iPad 1 had to be replaced because I couldn't connect with any network outside my house or an apple store; my first macbook (which is still the same one I currently own) had to be taken in the second month of use for the "airport card not installed" message popping up. If my screen was angled at a 60* angle, then the card would show during boot up, if the screen was opened all the way, the card would not show up as installed. (yeah, believe it). Is it the aluminum, the plastic, the chip? Or is the software?
After they fixed the problem, I went a year without any problems, but since I installed OS X Lion last year, I am constantly having to change network settings, making a new location, and renewing the settings - every single time to be able to use WIFI. I've tried every fix on the forums, If anybody has any suggestions, I'd be happy to hear it.
