After searching and trying everything we found a solution, worked for me and my friend was going into your router and changing the MTU value to 0 or auto configure and apply settings. The max value in windows is 1500 and after checking windows it was already at max so we checked the router and thats where we found the issue. The higher the number the better the results.

After changing the values we never encountered another connection or lobby drop problem. So spread the word and hopefully this will fix everyones else problem so we can all enjoy this game.

p.s. maybe the devs will see this and implement a patch to fix this issue so other dont have to worry about it
