[The network connection has been lost... when my internet it fine.]

is there any fix for this yet as I am getting constantly disconnected 😡😡😡

[“Fail to connect to server”]

I am having a similar problem however when I am playing a mission I continuously get disconnected and the game is left unplayable. Nothing wrong with isp as been playing other games online without any problems at all. Only been happening for the past 2 weeks so something has changed in the game. I have tried full reboot, hard reset, reset router, reset all custom network settings to default but nothing has helped. 

I really want to play this game and I don't want to just uninstall after all the time I have put into it. 

Any help?
