My 13" black Macbook has served me pretty well over the past 3 years, the only complaint I have (besides the TERRIBLE superdrives they used for this issue of Macbook -- mine failed within weeks of getting it, Apple denied it was an issue and did not cover it, but I digress) is the airport wireless card. It seems that periodically the airport card will drop internet connection BUT not the wireless signal. So essentially, the computer says it's connected to the network but my internet connection stops working. To fix this I just restart the airport card and the internet connection turns back on. This can get quite annoying as sometimes I have to do this multiple times per hour. It's not just my network, as it does this both at my house and at my apartment at my university. Is my airport card just merely dying out? Any help is appreciated.
