Randomly, at least once a day, my internet goes down. Lasts for 5 to 10 minutes. It's not just the wifi, it's the internet as a whole. I have my game system plug into the router, it goes down as well. Can't stream anything on tv, can't use a tablet, pc, nothing. Yes it's not long, but it happens so often. All I get when I call Comcast is to unplug the router for 10 minutes and plug it back in. Really getting annoyed. What can I do to stop this? I would like to use what I pay for without interruption.
