Wi-Fi or PLC?

[ogs]

This is a common problem unfortunately. Wifi clients associate with remote access points even when there is a local one with much stronger signal and some times also less congestion. I used to work in an IT department. We had thousands of wifi clients (class rooms in schools for example) and had clients connecting somewhere else in a campus all the time. We never actually figured out how to prevent this from happening and concluded that the selection algorithm, which was embedded and hidden, had weaknesses. The only real remedy to this was to skip wifi and use point-to-point ethernet wiring instead.
