I've had my macbook for about a year now and its completely growing on me so I am in the process of switching over to all mac products. Anyway my issue is this... Whenever I leave my macbook (which is connected to wifi) for a period of time (over an hour) and come back, the internet connection doesnt seem to stay connected. Meaning if I open safari a web page will not load. To fix this I usually have to turn the aiport off and back on and it works no problem. Is this an issue with the macbook or the router? I have a dlink 614+. Is there any settings I can change? This is even an issue if the internet is being used while I'm away such as a file sharing program. The macbook will cut off the internet. Its not in sleep mode or anything, just the screen shuts off. Help would be awsome!
