C7000 Nighthawk WiFi Dropping Randomly

Hey all, I've been having issues with my c7000 router. The first few months we had the router it was really good. But for whatever reason the wifi will just kill itself about every five minutes or so. The ethernet will still stay connected with no packet loss or anything but it's like the wifi just shuts it's self off for a few seconds. From just a glance at the logs (I'm not an internet technitian) they don't from what I can tell show it doing whatever it's doing. I can provide the logs if needed, someone please help out here, it feels like we have a $200 paperwieght for anyhting that needs a constant wifi connection. Thanks.
