Spectrum - Partial Service Dispalyed in GUI along with OFDMA Upload Enabled

As a final update, I was notified today that a second case (42933871) was opened with Netgear Support who advised I check cables, filters and factory reset the modem.    All the stuff that has been performed numerous times and was documented in the first case which apparently they didn't look at.    I'm not sure why that suggestion was even offered as the same thing occured with a second brand new CM1200 but did not occur with a Motorola SB8200 or the ISP's own modem.  

The CM1200 is a pretty neat modem but unfortunately it doesn't seem to work well with Spectrum or with the OFDMA, is minimally supported by them (even though it's fully approved now) and the Netgear support number hasn't really provided any options other than to contact the ISP or the bare basic troubleshooting I mentioned above.   

I'll have to return this device as my 14 days to do so is about to end to do so.  

Mods, please close this topic as not a lot of help occured on the forums either and I'll be going back to another modem type.
