Can't connect 2 Xboxes at the same time. Just got a new router, same problem.

So when my fiance moved in we thought we would get to game together, but this hasn't been the case. My xbox is wired, and hers is connecting wirelessly. If I'm on, and she tries to get on, sometimes it will boot me, sometimes it won't let her on, and sometimes she can get on but we can't play together without being booted.

I did some research and saw that the router I had didn't play nice, so yesterday we went out and purchased a Motorola SBG6782-AC, to replace my old modem and router both. I just got this thing activated an hour ago, and we have the same problem. The wired xbox is currently getting error code 8015190E, which is what we usually got when we couldn't sign in, but the wireless xbox is connected. 30 minutes ago, the wired one was connected and the wireless was getting this error code.

Could the fact that our profiles exist on both xboxes possibly cause this or do I need to do some changing of settings somewhere. Please help.

Hey there, in order to have an optimized gaming experience with both of your XBOXs, make sure that your NAT setting on the router is open. To learn more on how to open ports, visit this link: support.xbox.com/.../network-ports-used-xbox-live

By the way, NAT's purpose is to allow multiple devices in your home to access one internet line and be connected online simultaneously. Be sure to keep it open.
