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...

Got it new in March from Netgear under warranty; was replacement unit as my old one had several of the LED lights burn out. If I had been thinking would have confirmed the firmware on it when arrived. Started acting up in May, which is when the cox tech said he thought Cox had pushed out V6 of firmware.
Will keep on Cox ISP, but even the Cox tech said he was unable to directly interface with the DOCSIS engineer group. With Cox's pending merger with Spectrum not sure how anything is going to be handled going forward. 1st and 2nd tier customer support, off shore mostly, is terrible, I know more than they do, which is not much.

OK, send your info to NG. Ya v6 came out a few months ago. Hopefully NG can make contact with Cox in that direction and help them push prior working FW to your modem.
