Wireless access points or mesh networking?
My answer to Wireless access points or mesh networking? on Ask MetaFilter
I recently acquired the Netgear Orbi based on this recommendation in the wirecutter and it provides excellent fast wifi across our whole apartment where our previous non-mesh router failed to do so (tested using fast.com)
It has parental controls via the Netgear Genie app but I have no idea if they are any good.
