Years ago when we got cable, the cable guy installed a T Box, a box just called a "Technicolor" and a Motorola Surfboard.
Today I noticed that the Technicolor box had a wifi light on it, that got me pondering and so I turned off the Motorola Surfboard and found that it didn't do anything!
My wifi still worked, the same as always. The Motorola was plugged into the TBox via the LAN, and drew signal from the cable. Yet another cable went directly into the TBox via the splitter. Another cable supplies signal to the Technicolor.
I have no idea what the tech guy was thinking in wiring up the Motorola. Anyone know why this might be set up like this?
