Gwen from Pomona, CA
Netgear Orbi mesh router

Gwen has internet through Spectrum. She's looking at getting a NetGear Orbi mesh router. Will she have issues with her phone service? Leo says that she will because Spectrum requires their router to use their phone service. But she can hook them up in tandem and have them coexist. It works with Comcast in a similar fashion.
