@cp2000 The 3 white things are WiFi smart switches (well... plugs). The ones for the cable equipment are tied to the WiFi on the DSL line, and the ones for the DSL line are tied to the cable WiFi so that I can remotely reboot one network at a time from anywhwere.
The bigger white thing I think is a scam. It's supposed to somehow modify the wave frequency of the hydro (electric) service to reduce your bills, but I think they're a blatant scam.
