Dave wants to replace his Airport Extreme with a mesh router. Leo says that's a good idea since Apple has stopped making routers. Mesh routers are good because they are always updated and provide great coverage around a large house. The downside is that to get additional features and updates, he'll have to pay around $100 a year for that support.
Paul has Spectrum internet and is using an Eero mesh router. His bandwidth was upgraded to 100 Mbps down, 12 up, but he hasn't noticed an improvement in speed when streaming. Leo says that he'll want consistency over speed when it comes to streaming. Every device wants to be first on the network to get priority and "shape the bandwidth." It's all about quality of service. He may want to look at his cable modem. If it's older, it could be the weak link in the chain.
