You are considering using an InvizBox 2 with a WiFi mesh and are wondering if this will work.
The short answer is yes, the InvizBox 2 works with a WiFi mesh. It is a normal router and therefore you can put a mesh behind it.
The full answer will depend on what you want to achieve with your InvizBox 2 and also with your mesh. The main element to consider here is around what functions you want to use on your mesh and what functions you want to use on your InvizBox device.
For example, if you want to have parental control or device specific functions on the InvizBox, then the mesh needs to work in bridge mode (which for example the google mesh can't do easily - here are some discussions around this on user forums: https://productforums.google.com/forum/#!topic/googlewifi/idqXWjr69Ek). That limitation is around MAC address filtering typically.
Typically, if the MAC address of your devices is not available to the InvizBox 2 (because all traffic comes from the mesh MAC address), you will be able to have everything working (multiple hotspots with different VPN locations, ad blocking...) but not parental control and MAC specific routing.
So, If you want the InvizBox 2 to be in charge of the Privacy and use MAC address based features, you need to find a mesh that is made for bridging (which doesn't seem to be the standard).
NOTE: at the time this is written, we don't have fully working InvizBox 2 devices yet and so this article may get updated when we're able to test some of the above more thoroughly.
