Verizon's "Fios" (fiber-optic service) TV uses fiber-optic cabling. In contrast, Spectrum provides conventional cable solutions that use coaxial cords. so "maybe" you might need to re-run the Internet Setup on your Orbi, when you connect everything to your new ISP if you notice that the Orbi is not connected to the internet just go to http://192.168.1.1/index.htm and click on "Internet" and simply re-run setup. chances are however that you won't need to do anything.
