Now Spectrum has updated the CM3000 to version 6.01.03 - they refuse to roll it back
This darn broken firmware has made its way to Spectrum. They refuse to believe the only solution is to rollback to 5.0.X as proven method by Xfinity and other ISPs who dealt with this mess months ago...

Here is the reply we're getting from Spectrum. One of you is wrong!!!!! Either way you and Spectrum need to get together and set this fixed instead of leaving your customers with a $300 piece of garbage boat anchor Telling us that we don't matter to either one of you.
All -
We reached out to our engineering and communications teams and were able to get clarification on this issue.
While firmware updates are generally tested on our network and sometimes pushed by the ISP, the Netgear CM3000, which supports symmetrical speeds, has been whitelisted and firmware updates are pushed directly to the consumer from Netgear. You will need to contact Netgear directly for a resolution.
A workaround until Netgear resolves the issue would be to use a non impacted, approved modem or you can use a Spectrum provided modem, free of charge. Spectrum provided modems can be obtained by visiting your local Spectrum Store.
