[Blind-sysadmins] static dhcp lease, Arris RACV1A router

Hello, I'm not sure how widespread this router is so it might be to list members in the US only. Does anyone have, either purchased, or provided by your ISP, a Wave2 router, specifically an Arris RACV1A model? If so, do you use it with a screen reader and if so what techniques do you use, IMO it's not to accessible? I'm wanting to set up a dhcp reservation for a printer and one for another fixed device. I've got to enter the Mac and the IP, it doesn't say which field is which and it doesn't tell me the format the mac will take. This is with both Jaws 2018 and NVDA 2018.2. Any help appreciated. Thanks. Dave.
