My house needed some WiFi amplifiers due to the fact that the router is on the ground floor, the walls are thick, and WiFi was limited. He arrived promptly, assessed the trouble areas, and started the install. Very pleasant and courteous. After he left a few hours later, (WiFi was working great up to this point) it dropped. It only took us to realize to disconnect and reset the amplifiers installed in the electrical sockets to get the signal to "reboot." We were unaware of that, and it has happened periodically, but that's not a major concern, more an advisory issue.
