Well, I did go _all the way_ to Best Buy for the 100′ CAT-6 cable.

Yesterday, Tim Ward mounted the receiving dish at the north end of the roof. The WiFi router had been mounted in a plastic tub on top of the shipping container and it got kinda crushed during the roofing work.  The tub was destroyed and the router-case was cracked open but the circuitry seemed intact.  The blinky lights came on momentarily yesterday when first plugged in, but no joy after that.

Today I double checked the power cords and then got up on the ladder and scrutinized the router.  Found a power switch partially obscured by grime and gunk.  Blinky lights came on,  phone got CSS weather via wifi.
