CM1200 to Rax200 WAN aggregation slows down (requires reboot)
I have a CM1200 modem and RAX200 Router with WAN agreggation (2Gig). My internet speeds slow down to 25Mb after approx 24 hours. Rebooting the router fixes the issue for another 24 hours and then the...
Checkout the following link for your question:
I have my port aggregation turned off on CM1200 and just using the Internet port on RAX120. Just didn't want any link aggregation while troubleshooting the Cm1200 modem connectivity issue.
Still roubleshooting the issue (3 months now). Don't use Link Aggregation basically changed everything (coax cable, ethernet cable, etc.etc.)
However, I did notice the firmware on CM1200 (Comcast) got upgraded to V3.02.01 this morning. Looking for release notes for V3.02.01 and not published on NetGear yet.

It won't be. Netgear cannot publish firmware for CMXXXX devices because cable ISPs don't allow it.
If your firmware is outdated, you cannot manually upgrade your cable modem’s or modem router’s firmware. You must contact your Internet service provider (ISP) to upgrade your firmware.
That is correct, firmware is pushed by ISP. However Netgear has a page which points to a Netgear knowledge base on CM1200 firmware:

The Netgear knowledge base shows the Comcast deployed firmware for CM1200 product (and other netgear products and service providers):
Knowlege base's last update is 9/22 and still shows the old firmware.
FYI. My home system is CM1150V and Orbi Wifi 6. ISP is Comcast. I have had the same problem of slowing with WAN aggregation. Comast finally pushed a new firmware this week,
version V4.02.02.I re-enabled port aggregation and for now, seven hours later, there has been no slowing. I am still cautiously waiting until 24 hours to pass final judgement.
