said by TomBeckman:The reason I posted the question is that I asked multiple Comcast techs about the power numbers and they all said that they didn't know what they meant.
Were they techs field techs or tier 1 phone support techs? The business class tier 1 phone support techs generally are familiar with the SMC gateway setup options to which they have access, but I suspect that some of them have never touched an RG6 coax cable or an F connector.
The "two" high frequency channels are definitely wonky, especially the fact that they both show as being the same frequency. It is hard to believe that the SMC's modem actually shows them as "locked". I would say, that in effect, you only have two downstream channels that are actually bonded. Since it is happening on two modems, it is likely a Comcast infrastructure problem (but if it is not causing you to have connection or throughput problems, it may be difficult to convince Comcast to even investigate it).
As for only seeing three upstream bonded channels, that is all that I have ever seen on my connection, and for the couple of days I was on the borked 3.1.4.51.1 firmware last week, I only had two upstream bonded channels.
