I have confirmed that this firmware downgrade occurred with my modem, and that I have received the same notice from Comcast.

Thanks for the input!
I have confirmed that the bulk of my problem is the Zyxel USG60 router. I put the drop amp back into the circuit as I would normally have it but plugged a PC directly into the modem for testing. While I am still seeing the previous events, with the USG60 out of the path, I am now seeing 940/25.
Apparently, the issues were the USG60 router all along.
As for WIFI, I already have a mesh system with 3 nodes (overkill but works).
I will be exploring firewall/router devices for something that has better throughput based on my service tier. The speed issues are NOT caused by the drop amp!
Thanks for the patience! Any recommendations for firewall/router in this speed tier would be appreciated. I'm considering the NetGate 4100 for a bit of future-proofing that meets by speed tier.
The USG60 is considered obsolete and no longer getting updates. Guess I have a better understanding WHY it is obsolete!
Power levels are good and on the higher side but with in specs.
Still seeing Criticals that are indications of a problem on the ISP side of the modem.
No big surprises there, as I have pretty much already figured there are issues on the ISP side.
I may still try putting the splitter in front of the amp, which will reduce the power level seen by the modem. However, it will also reduce the outgoing power level unless the modem compensates for that loss. I don't personally think that the amp is the problem, but this additional step will eliminate that variable. I'm ok with PROOF that I am wrong!
I think moving to a splitter will alter the incoming power to somewhere around -2db or a bit less, but certainly above -7db.
Or find you a -3db barrel attenuator that fix coax cabling. I had one for mine until I didn't need it anymore.

Just for kicks I did install a -3db barrel. Interestingly, I saw no significant change to signal levels. Apparently, the modem negotiated levels to keep the input and output close to what they were.
No significant speed change either. This I expected.
However, if anything the critical errors are the same or have increased. With the modem outbound power the same, the ISP would now be seeing approx. 3db LESS. One outbound channel is listing 43.5 and I think the spec is 45-51db.
With no significant change, I am removing the -3db attenuator, as it would further reduce the outbound power to the ISP.
For the sake of completeness, I will omit the rest of the wiring and go directly to the modem. I'm betting on similar results.
Note that I am receiving the following, apparently indicating an incorrect vendor config file:
Also, connection directly to modem made no discernable difference. Power levels are the same, events are the same:
Approximately 30 feet from outside connection to the modem via RG-8.
Correction: incoming power levels are down approx. 3db as expected with the amp removed.
Something the ISP will need to take a look at. An onsite tech visit maybe needed.
Correction: All my previous references to RG-8 are incorrect. The cable is RG-6/U and the connectors on the RG-6 are Digicon DS6.06-03.
The runs to the TV are RG-59 with Digicon DS59-02-03 connectors.
Incoming cable is currently direct to the modem with approx. 30 ft. RG-6.
I will be contacting Comcast, hoping this can get settled, at some point when I believe to have the patience.
Upon further research, I have found reports that the Zyxel USG60 router may be my limitation. I found reports of this router handling a mix of UDP & TCP traffic with common features enabled maxes out around 350mbps. I have been getting ~380mbps.
VERY DISAPPOINTING!!!!
I'm going to bypass the router briefly for some throughput testing and most likely moving to a pfSense solution after confirming that the USG60 is the bottleneck. The same reports indicate that this router maxes out around 520mbps WITH ALL FEATURES DISABLED. Naturally, a firewall with the firewall disabled is not really much help!
Any other router recommendations would be appreciated. I'm thinking pfSense for the open-source software and support and investigating what hardware to use.
Thanks!
RG6 is needed for any Cable modem connections from the ISP.
RG59 is only for TV connections. Make sure RG59 is not being used to connect the cable internet modem to the ISP.Find a router that best suites your needs and covers home size for wifi coverage. Mesh system maybe needed. Good Luck.

Zyxel are mostly used by ISPs. I can't recommend ISP equipment. Especially there routers. No really the best out there and there is better. Even NG has better routers.
Sounds like you narrowed it down the this branded router as the cause.
