It’s a Uverse branded Pace Plc 5268AC. I couldn’t find a manual for it online, but it doesn’t appear to have the DHCP reservation feature. I find that more disturbing than the Tablo not have a network configuration app.
Is there a configuration app that you can get to on the Tablo via ethernet?
There isn’t anything like an app or other interface that I know of. I know that the support folks from Nuvyyo have a different interface that allows them to do much more, but I’m not sure of its limitations. Might be worth opening a support ticket to ask. It might also be time to buy a better DHCP server or router.
