Hello, I just purchased the new Macbook. I leave my computer open so that I can recieve instant messages when my friends need to contact me, but I noticed that sometimes when I wake my computer, the Wi-fi cuts out. I'm not sure if the wireless cuts out the whole time it's sleeping, or just for a second when it wakes? Does anyone know what I can do to change the settings? When I left my old Macbook open and it went to sleep, nothing happened to the wireless.
