No more LAN games

Before the update I was able to play LAN games regularly with my partner (he has his own Xbox/TV set up) after the update we can longer play LAN. When he is playing on his console his game does not show up on my console in the Friends tab under joinable games. My game does not show up on his console. After the Oct 29 update when we first noticed the problem we both did full shut downs and then full reinstall of the game and all of our content. We both have purchased the game from the XBox One store separately.
