One packet stream (connection) only use one WAN port

RouterOS Beginner Basics

I Merged 2x ROUTERS together with Mikrotik Routerboard 951ui-2hnd , DSL Router 1 = 2.5 MB Upload speed and DSL Router 2 = 2.5 MB Upload speed , at test speed with speedtest.net the result is 4.9 mb upload speed, but the problem is when i try to make a Live stream on Twitch or Facebook my max upload speed is 2.5 MB Not 4.9 MB ?! and when i watch my Mikrotik interface i find that it take upload from one router only not the two routers together.

So how can i fix this streaming upload issue?

Sorry for my bad english
Thanks in advance

It’s not that easy. Such config would have to be specifically supported by ISP (using bonding or something). You can’t just take two DSLs yourself and expect them to work like this.
