I have a 1-211M-K ONT connected via Coax to the Actiontec MI424WR Rev 1 router. I dropped the TV and now only have FIOS internet. I want to install a Google Nest mesh router to the ONT's ethernet port. Question is about the ONT. I see the 1-211M-K is no longer supported. Should I get VZ to come out and put i a supported ONT before I instell the mesh router? I"m not adverse to paying for a tech support visit to get this done and ensure a smooth install of the router.
