RCA modem diagnostics - anything bad?

I have two counters that are high in the event log. ANything bad here?

Is there a problem with your connection? Upload and download speeds what you expect for Comcast?

, cable modem FAQs. You will find the appropriate ranges for the SNR and power levels. I don't know about the log entries, but my guess is they are meaningless to the user and don't reflect a problem with the modem.

Can't ask for any better numbers on the signal strengths, and your SNR is excellent as well.

CIAO!

There is nothing problematic with your connection. Diagnostics data will report any minor problems as "history", its ISP's technician, admin useful data.

E.g. if you use LAN at office full time, you will see "collided packets" sounding awful, its meaningless if your network is running well. Network card/OS took care of problem.

Time to check diagnostics is, when you get half of your advertised speed, modem drops offline and calling support center.

Have a nice day
