For their 1.2 Gbps plan, Xfinity only lists 3 approved modems that are supported (excluding ones with wifi and telephone, which I don't need): Netgear CM2000, ARRIS S33, Motorola MB8611.
1. Will Nest WiFi Mesh perform equally with any of these? Any recommendations?
2. Would Nest WiFi perform better with any alternative modems, (i.e., ones not approved by Xfinity)? If so, any downside to not using a non-ISP approved modem?
3. I am currently using a Netgear CM1000 with Nest wifi and getting 900 Mpbs/40 Mbps on Google speed test. Is it worth upgrading the router?
