Recently brought a lennar smart home. Previous owner did not use the rukus system.
I have got at&t fiber. At&t fiber modem is in the master bedroom. The smart home box is in the laundry room.
I connected the Ethernet cable from at&t in master bedroom, then the master bedroom Ethernet cable to rukus device (ICX 7150-012p) in the smart home box.
The rukus device doesn't seem to be getting the internet. I connected a spare router to the Ethernet cable in smart home box to verify. The router works just fine.
