I bought a brand new macbook retina. I don't know if this is a hardware issue or a OS issue. When my macbook wakes from sleep, the wifi connection shows connected with IP address but it will not load any internet sites. I have to turn the wifi off and back on to get the webpages to start loading. I've did some research and redid the network preference and configuration files with no luck. My macbook air I sold before I bought the Macbook had no issues as well as all my other devices. I set the macbook as a new laptop and did not restore from backup. Is any one having this issue and what did you do to fix it?
