I would like to speak about using Setek WiFi extenders in a multi-AP network configuration. They are not quite enterprise level gear, but they do a good enough job of extending coverage. The more difficult part is when people think they can simply mount the unit to the wall and move on. And then they get into an AP network, it is much more complicated. https://techwifi.stck.me/post/1349510/Integrating-Setek-WiFi-Extenders-into-Multi-AP-Network-Infrastructures
