Problems with Halo The Master Chief Collection

Hi, I’m mainly sorry for my bad English, but I need some help, I’m playing the HaloTMCC campaigns with a friend, but just in the third game he keeps disconnecting, which is very annoying since the stage completely resets, they are not our internets, so if anyone can help I would appreciate it very much.

So I’m not the only one who struggles with this?

Now, I don’t have the best internet connection, but halo 3 has been the only one that it has consistently disconnected for me. The others run just fine. I don’t know about any solutions, because it looks like a problem on the developers end, probably. If anyone else is experiencing this, which I assume others do, specifically with Halo 3. Maybe the game needs a patch? I’m no expert, so I could be totally wrong, and I might actually have just really bad internet causing the problems.
