Keep in mind that Comcast has a (arbitrary) data limit of 1,200Gb every month. If you stream a lot you can easily hit that. They’ll happily sell you an unlimited plan for an extra $30 a month on top of whatever rate you have though, or it’s $10 for every 50gb over you go till you hit $100+regular monthly fee.
I used 2,287Gb of data last month, but I have a wife and kids who like the background noise and I’ve downloaded some games for my Xbox. 1.5Tb-2Tb isn’t abnormal for us though.
Otherwise we have Disney+ (includes ad supported Hulu), YouTube Premium, and Motortrend On Demand and I find that to be enough, though I couldn’t care less about sports or regional channels.
I’m using an Arris Surfboard modem and Asus RT-AX58U router. Best router I have ever had, I say stay far away from NETGEAR… my last one lasted 8 months before failing, the one prior a year. My router is in about the worst possible location (in a stairwell on the lowest floor sitting on the ground) but manages to blanket my entire tri level in 5G Wi-Fi no problem.
Edit - I have a 100mbps down/10mbps up connection. It’s more than enough for both 4K TV’s and 2 phones all streaming at once.
