Increasing Bandwith Limit

Greetings, I am getting rubber banding even on local multiplayer set with no Network Emulation. Problem seems to be originating from an internal limit on network bandwith and since my game is horde shooter i am easily surpassing this limit.
(It is fine on small number of AI units such as 15, but when numbers approach 50 rubber banding starts to become game breaking)

In past, following method was used to increase bandwith limit but it seems config file has chanced and there values do not exist anymore in it.…E4%20AnswerHub

So, how can i increase the current bandwith limit in UE4?
