About once an hour or so my Macbook Pro completely stops sending or receiving data through Wi-Fi. It does not disconnect from actual Wi-Fi connection or anything, but websites do not open and I'm being disconnected from services that require constant Internet connection. Such event lasts usually about 10 seconds and then the connection is good to go again. Router used is the newest 2TB Time Machine which works perfectly fine with all other devices connected to it. What could I do to troubleshoot this issue or should I just bring the computer to Apple Store for warranty service?
