CAX 30 and XFinity Upload Speed
i have a cax 30 and my xfinity service is 1gb download, 100mb upload. i get somewhere between 500 and 800mb download (which i guess is okay) BUT my upload speed is stuck around 25mb (which is not...

1. i can't get nextgen service at this time regardless of my modem.
2. even if i did have nextgen service, my cax30 is not yet capable of that (even though it is a recommended device)
correct?
Your specific service address has not yet been updated to receive the Xfinity Next Gen service. Work in progress across the Xfinity service areas.
Your CAX30 does not have the updated firmware necessary to allow it to connect to the Xfinity Next Gen network. The list of devices approved for Next Gen network connection is updated by Xfinity every month or so.
Yes, correct.

it would be nice if xfinity made this clearer. when it calls my modem/router "recommended" and that i have 100mb of upload at my location, i consider that very misleading and false.
xfinity needs to make it clear what upload speeds the modems can achieve. if they want to say "these are recommended but we are still working to deliver the faster next gen upload speeds" that would be fine and more accurate.
as for netgear, the same can be said. "not currently able to access next gen faster upload speeds at this time; we are working to make that happen."
frustrating. i'll probably return the modem/router and i will definitely be downgrading my xfinity service.
NG spec sheet for the CAX30:

Though it doesn't really give max supporting speeds of the modem thru the router, you have to look at the LAN ports and there capacities and limitations. There's 4x1Gb LAN ports, Just a signal LAN port will max out at 1Gb thus you see just over 900Mpbs speeds, nothing past 1Gb. Now the CAX30 has two LAG supporting LAN ports, so theoretically and technically if you had an ISP speed on the ISP side coming down to the modem and you had LAG enabled with a LAG supporting device, you could see up to 2Gb speeds approximately. RG coax cable speeds support way over 1Gb and working beyond 5Gb now with Docsis 4.0 spec. So the modem side of the CAX30 can handle beyond 1Gb, it's the LAN ports that are limiting and will never see beyond 1Gb. Users of NGs CBR750 ran in to same thing this past year or two after the ISP discontinued the 1Gb plan. Caused problems for lots of users.
The CAX80 has 1 Multi-Gig LAN port that supports 2.5Gb connection rates. So if you had this model modem, ISP got you at 1.2Gb package, you would see 1.2Gb thru the CAX80 on it's multi gig LAN port.

All this is mostly on them.

If you follow either of the two following links and scroll down to speeds, you will see that Xfnity has reinstated the 1 Gbps service tiers for all of their divisions.

In general, Xfinity communications are deceptive and disingenuous. They must pay someone handsomely to write that stuff. It cannot be made up, even with AI.
