Disconnect if two computers in the same home try to play together.
OK so I found a fix from an old Titanfall 2 issue thread that spoke about NAT types and Nighthawk Routers that appear to be the main router with this issue.. This just worked and my son and I played successfully in 3 matches already.
FROM OLD FORUM:
I solved this issue by going into the nighthawk settings
Advanced > Setup > WAN Setup
Change `Nat Filtering` from `secured` to `open`.
Additionally you can reserve the IP's for the devices on the network that will be playing multiplayer to keep them from changing. This is especially useful if you're on a wireless connection.
Advanced > Setup > LAN Setup
Click the `add` button under the `Address Reservation` section and select the device you want to reserve the local IP for.Hope that helps some people!!
Cheers!!
