Try a different CAX modem? If all as been checked and tried, possible faulty unit is all.

Still dropping with sync errors. Is this normal at all? Is there any reason that I should need to reboot the modem periodically? With my ATT modem (previous house) i never had to reboot. The XFinity modem does not crash either. I don't want to use it or pay the extra $$ to do so, and it has less wifi range than the Netgear CAX30

So after a lengthy chat with netgear support, they have told me that my downstream power is too weak. They told me that it is supposed to be between -7 dBmV and +7 dBmV. Mine is running between 4 and 5 dBmV (see above info).
If I am at +4 or +5 dBmV, how is that too weak when the recommended band is MINUS 7 to PLUS 7 dBmV? It must have been a language thing because "Sharon" and "Fatima" told me it is too weak at PLUS 4.
They quoted me this FAQ: https://kb.netgear.com/24311/Power-level-guidelines-for-a-NETGEAR-cable-modem-router
"Good Downstream power levels are within -7 to +7 dBmV."

Yes.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.Your modem should not need a reboot or power cycle to correct anything unless your troubleshooting something.
