Thanks for the response Zack..
1) No wifi at all. Both pc's are hardwired direct into routers.
2) Time zones are both the same
3) Download regions are the same
4) Nothing changed on firewalls as I mentioned before we were playing FM22 online perfectly fine , never dropped connections until we made the switch over to FM23. Nothing changed other than the game.
Also would like to add sometimes when my buddy gets disconnected he will be unable to rejoin. I then have to go to online preferences, allow users to join the game change it to No, confirm and then go back and change it to anyone or friends only so he can go back in.
This is happening so much that its really so frustrating to play.
