wifi is a dark art. Getting total coverage in a home is almost impossible if you want to stream high quality. Added to the list above we’ve found cinderblock buildings block it, as does metal backed plasterboard (still very common) and the new insulation materials. There is no point in investing in fancy routers in these properties, far better to either run ethernet cable or buy a mesh. Even the cheap meshes are better than the most expensive routers.
It certainly is a challenge to get the best connection in your home when your home is the thing you’re fighting against! Very interesting with the metal-backed plasterboard! I wonder if this will have to be altered as people convert homes to smart homes and add more devices
That’s a great money-saving tip as well with going for cheap meshes rather than expensive routers
