I just bought a black macbook last week but my airport card seems to have problems. The thing is that sometimes when Im browsing the internet, the connection seems to drop because websites do not load and itunes wont connect to the store. However, when I check the signal it says that it is connected and the signal is good and everything starts working again. If I dont click on the wifi meter to check it, safari wont load the page at all. It seems to happen randomly and it is not my router's fault because it also happens in school and at my friend's house. This issue is really frustrating because other than that Im perfectly happy with my first Mac ever.
