Tutorial - How to create a mesh network using multiple Synology MR2200AC routers

This tutorial guides you step by step on how to set up a mesh network using multiple Synology MR2200AC routers. The Synology MR2200AC is Synology's latest mesh router, and combined with the powerful SRM (Synology Router Manager) software, provides for the best mesh network I have tested (performance on par or better than with Ubiquiti). This is my first tutorial, so please comment (good or bad), and enjoy the tutorial.
