Captain, it makes sense you're focusing on videos instead. I understand about gateways and routers, but I'm eager to switch to my own setup. Keeping up with the newest tech can be a challenge, though.
Modem options include Cm500, CM600, and SB6183. Docsis 3.1 modems should generally suffice. For achieving the advertised 1.2 Gbps speed, you’ll need a modem with a 2.5 Gbps Ethernet port and a router featuring a 2.5 Gbps WAN port. Link aggregation is an option, but it’s limited on routers. For 100 Mbps, any model should function. I wouldn’t recommend 4x4 or 8x4 modems, as Comcast appears to be reducing support for them. The Synology RT 2609AC is a solid choice for me, though it’s a WiFi 5 router priced around $200. Someone might suggest a more affordable alternative.
For upgrading to a multi-gig tier, consider this guide. Many suggestions include at least one 2.5Gbps port for LAN/WAN, though more advanced models may cost extra.
