Yeah, I've tried that already (as well as Kismet, Wavemon and others on
Kubuntu).
Issue is, they detect WiFi and not other, non-WiFi RF.

Not sure if DD-WRT allows me to control power, I'll have a check.

Again, not sure I have control of that; but I'll check.

It is rather close to the TV and an RPi. I guess the another test will
be to move the router to a new location and see if that helps.

I guess I can also see if the VM SuperHub shows a similar issue or not
byt taking it out of "modem mode" for a period. If the SuperHub is OK,
it must be some config gremlin in the router.
