Hi John,

In this case the Internet is not via DSL, it's via cable.  The coax comes out of the ground and then to the modem/router and from there via a 150-foot Ethernet LAN cable to the granny unit, where there is an additional router with its own Wi-Fi.

Anyway, that entire system was turned off when I threw the main breaker to the house.  I assume it could be caused by Internet from some neighbor, but as I said, the nearest neighbor's house is about 150 feet away and all services are underground.

It's a puzzlement...

Hi Alan,

I've had issues with the service from street to modem. As I understand,
there's a VDSL band which overlaps 7MHz band.

In my case, it was reversed, any transmission on 7MHz would disable TV
and Internet service.

The ISP is TDS.  They offer up to 1 Gbps internet (I only pay for 200
Mbps) via cable.

Just as a sanity check, I just walked down to the main house and
unplugged the 150-foot LAN cable from the modem/router that feeds the
router in the granny unit here where the shack is.  As expected, the
spurs are still there.  There is no wired connection from the K4 or the
desktop computer to the LAN (Wi-Fi only).

The weird thing about these spurs is how clean and stable they are.
