The Synology MR2200ac is a mesh router designed to be bought in pairs. As an alternative to using wireless extenders, or powerline adapters, a pair of MR2200ac's work as a team to broadcast wifi easily from a base unit to a secondary unit that can operate in a more central location of your home.
It stands out for its inclusion of a secondary 5GHz wireless radio purely for its own communication with others of its kind. That way, your internet experience is never hampered by the devices communicating with each other.
Aside from its (comparative) ease of use and setup, the SYnology MR2200ac is extremely capable when setting up protections for younger members of your family. Customizeable schedules and protections for individual family members mean that as you protect the most vulnerable in your household, you won't have to sacrifice perfomance for your own needs.
