xFi Complete + Gigabit x2 package: abysmal performance.
I was on Gigabit pro with 1Gbps download and 40Mbps upload. I upgraded to xFi Complete and Gigabit x2 package (with 60% increase of the monthly service fee), and I activated the XB8 modem (software: CGM4981COM_5.8p5s3_PROD_sey). Now from speedtest.xfinity.com , I only get at most 100Mbps download, s

This seems correct and I can confirm that my T25 setup works well. I have a T25 which Xfinity shows as incompatible with my 1.2 Gbps plan, but I get almost 1400 Mbps using my ASUS router's speedtest and sometimes >1200Gbps from speedtest.net on m
Arris T25
The Arris T25 modem shows up as being supported by Xfinity. Has anyone recently tried and successfully provisioned this modem with Xfinty? Does Xfinity push the most current firmware out? Have you been happy with the Puma7 chipset? Any input would be helpful. Thanks!

XB7 vs XB6 initial performance disappointment
My wired download speed on the XB6 was over 1100 Mbps. The wired speed on the new XB7 caps out at 950 Mbps. Is this modem relatively deficient, or has the overhead cushion on my gigabit service been eliminated? The wireless speeds are also not as robust throughout the house as the service I enjoyed

Upgraded from 1000 Mbps to 1200 Mbps, but still lucky to get 300Mbps tops
I have a CAX30 modem with the latest firmware. If I run a speedtest from the CAX30...it's 300Mbps on a good day. I ran a cable connection diagnostic from the modem and this is what I got. Does this look ok? I do see channels 23 and 24 with the lower SNR and power difference. Could this be causing me

Speed has been less than 50% of high speed plan for several days. I spent a lot of time with the "Xfinity Assistant" running tests.
