Netgear night hawk ac1900 smart Wi-Fi router model R6900 v2

This item is from a pet, smoke free location. I’ve been using it in my home for the past couple years but had to upgrade to a modem/router joint machine for my new internet subscriber. It doesn’t have the original box/instructions. It also doesn’t have an Ethernet cable. It does have the original power cable. The second black antenna thing is loose. Please view all pictures for the cosmetic ware.
