client-to-eero bandwidth speed test
It would be a really nice feature if either via the app or via the internal URL that customers can easily test the client-to-eero bandwidth (and client-to-gateway). This is a little more complicated in a mesh situation because there is client-to-eero AND client-to-gateway. Extender eero should internally be able to use this feature to test eero to eero, in order to compare extender placements (and make helpful suggestions) and mesh paths.
This feature would provide an empirical tool to compare eero placement and also help isolate whether it's the ISP's fault or eero's fault. We can already see the gateway-to-ISP values, and this feature would be a good complement to see what fraction of bandwidth is lost from wireless losses.
