So did some more digging and found a thread thats several months old but it appears the issue is Link aggregation and NetGear does not have a fix yet. :(

Ok, Thanks! Disabled it on both.

AdeptMaven and Huskuldar, to clarify, you are observing the link aggregation performance problem when using the new RAX120 firmware 1.0.1.122 (together with CM1200 1.02.02 on Xfinity 1000Mbps service) - correct?
In addition, I am curious: have you enabled IPv6 on the RAX120?
Thank you.
- AdeptMavenMay 17, 2020GuideAt the time I did not have ipv6 enabled. I have since enabled ipv6 but have disabled link aggregation. Should I try link aggregation with ipv6 enabled? Does that fix the issue?
- HuskuldarMay 17, 2020TutorYes, most current firmware, Xfinity 1gb service, IPV6 is enabled, link agregation disabled. After disabling link agregation service has been perfect.
