The MW3 looks good but I wouldn’t want to recommend something I hadn’t experience of. I believe the Google Wifi boxes can go up to six boxes. That might be general or it might not. If Edventure bought something which didn’t scale up to what they need, that wouldn’t be great. That said, the building is such a warren of stone corridors it might be mesh-proof anyway: can reach some rooms off the main loft space, perhaps, but little chance of reaching everywhere.
OK, we took the Google WiFi mesh routers out of service, put in Will’s very long ethernet cable and Danny’s old Wifi router, and now we have Remakery as our WiFi, with the password Remakery. It would be good to wall-mount the router somehow and perhaps tidy up the wire, but we’re already doing much better than last week! And it looks much tidier too.
(What this does is put stable and fast WiFi in the Remakery - the room where we meet, and where Make:Shed meet. What it doesn’t do is provide a seamless walk-around-and-stay-connected kind of experience, which you get from a mesh.)
