But to be honest, in a home setup why would you really want/need mesh. I have 3 AP, a Pro, lite and LR models - can do dynamic vlans, can do min rssi, can do band steering.. Has all the features I could possible need in a such a setup for very reasonable cost. And can do multiple vlans - if using dynamically assigned really almost no limit on the number. If you doing ssid based vlans then you would have a limit of 4 per band. I currently run 4 different vlans on my setup.
