Wireless Connection issue
Sometimes I will be using my macbook pro and for whatever reason my internet connection will completly lose its connection to the internet and nothing will be incoming to my computer. No messages pop up on the screen. My computer will remain connected to the network. My iphone has never had this issue, and when my computer fails to have any internet connection, my iphone still will. The only fix is turning off the wifi on the computer and turning it back on, really stupid. Any help would be nice as I don't know what's causing this connection issue of mine. Also this doesn't always happen when I use it, but it's happened enough to become a habit.
MacBook Pro (13-inch Early 2011), OS X Mountain Lion (10.8.2)
