Formerly supported device no longer supported?
When I bought my router/modem combo (Arris Surfboard SBG7580AC) it was supported by Xfinity. I confirmed this by finding this list which clearly includes this model
Now, Xfinity doesn't show you a nice list like this but they make you go to MyDevice. When I'm there it says "This device is not supported " and then "This device is compatible with your service download speed of 800 Mbps" Well which one is it?
If I try to find out WHY the device isn't supported (even though it's compatible) all I get is Xfinity pointing me to their shop to buy a new device. I don't want to spend more money, I just want to know WHY the device I purchased because it WAS on the approved list is no longer approved.
And I'm asking this because our Xfinity service is horrible and the internet just drops randomly, especially at night when people are watching TV.

yeah, I have to buy a modem/router (separate or combo) for my mother who is going to set up service with BYOD equipment in her retirement community studio and so am shopping now. I have been on Xfinity/Comcast since 2015 using my Netgear CMD31T modem and N600 db router. The modem is "not supported" now but still works. I would still buy low budget "unsupported" equipment for a Comcast coax since the planned usage is at the basic service level.
I think we are being transitioned to using equipment with more throughput/bandwidth as the speeds are improved with infrastructure upgrades up to the home connection. As cable TV comes to an end and people get gigabit speed to their door with transition to video streaming services (Peacock/Netflix/Prime/Hulu/Paramount+/Disney+/<fill-in-your-cafeteria-content-here>) with 4K / 8K (?) resolution in household of average 4 persons, you will need the latest modem+router tech, which means DOCSIS 3.1 (mine is 3.0) and at least 8 x 4 and better. Comcast can also check modem state better with the latest tech (I dont know all it can do).
But if you dont ever want better than 50 Mbps service, do email and web surfing, are OK with 720p streaming by maybe two people in the house, you're probably good for another decade as long as the lights blink in your modem/router.
