I've had this problem until last night. Do you use Comcast at all? They updated their routers to put out a secondary signal for free internet to people. This second signal interferes with the main one that the home owners are on. This causes the channels to drop all people connected then reconnect them. Hence why you can log back in shortly after being dropped. Had my computer genius buddy work on it 3 tines. Port forwarding, resetting the router, opening all ports. Nothing worked. Then he hopped onto our xfinity.com account, and disabled the xfinity hotspot (i called xfinity and they told me it was off. They lied so don't trust their phone people). Once he turned it off he set everything back to normal on the router. With that extra WiFi still off, and I have not had a single problem since. I looked for a month for a solve, and this is it. Knock that out if you're with Comcast and you'll have no issues anymore I guarentee. If I end up having the issue again ill let you know. If this didn't work and only got me a lil while of uninteruoted gameplay I'm buying a new router of my own
