Recent inconsistent connection issues

[R3_Frostbite 0]

Hey,

After the latest patch (1.7.1.5), my brother and I have been randomly having serious issues when connecting to the same servers. We've been able to play without issues for the past week or two since we've gotten the game, but with the recent patch, and more specifically beginning last night, we've been downright unable to connect to almost any servers at the same time. We're on the same network, and I'm wondering if that could possibly be the issue. When we connect to a server at the same time, both of us will get a random issue, usually lagging out during the "Receiving Data" part, never receiving the mission data, or just being kicked out while loading. If one of us connects to a server alone, he will connect and get ingame, but will lag out as soon as the other person connects (the other player will be kicked too). Both of us can play alone without any issues, and we'd never experienced it before this patch.

I'm not sure whether this is an issue with the individual servers themselves (we've tried probably around 10-20 servers to the same effect), or an issue with the most recent patch, or a known issue with a known fix. Just wanted to post to see if anyone was experiencing similar issues or had fixed it on their own.

Thanks!
