I have satellite internet at my house and i use a wireless apple airport, and I connect to the internet fine from my macbook. But since I got my computer fixed, when I have gone to school or someplace public that I know has accesible internet, it wont even show up under the avaliable wireless networks. And when I know the network name and password i try connecting but it still wont work. What do you think the problem is here? Im not sure if its something that the small dog guys did when they fixed my comp or if its something as easy as resetting something. Any help would be greatly appreciated, thanks guys
