Having a bit of trouble with my macbook's internet connection.. I have a wireless router set up.. and everything was fine when out of the blue my macbook lost the internet connection. So I reset the router.. turned everything off.. tried everything for 10-15 minutes. nothing worked. I checked my pc laptop just on a whim, and it was able to access the internet. I connected the cable modem directly to the macbook via ethernet cable.. and it still wouldn't go online. What gives?
