Disconnected from every server every few minutes

I have been unable to find a solution to this problem, and it seems I'm not the only one. After connecting to a server and playing for maybe 5 minutes, I am disconnected, without fail. Have tried a bunch of random solutions that some users have said have worked, but nothing has for me.

I'm on Windows 7, connected to a Netgear R6220 router by eternet.

Game seems great, but I'm considering getting a refund, as I can't play.
