Cox Cisco DPC3825 DOCSIS 3.0 Gateway drops connection at least once a day

Hello everyone,

I hope I can get some pointers here.  I've been having issues with my Cox Cisco DPC3825 internet connection.  For the last month or two, the internet keeps dropping at least once a day.  After a quick reboot, it is up and running but having it drop daily I'm sure is not normal.  I wanted to see if anyone has any pointers:

I thought I'd post some stats as well:

From the log:

Any help is appreciated.

I have only Cox HSI and have the connection directly to the Cox modem then to my desktop.  I'm out in Orange County.

Thank you

socaluser, 

When the connection drops are the lights on the modem going out? Is the desktop the only device connected or are you also connecting devices wirelessly?

Hello ColleenD,


Thank you for your reply.  The lights all stay on (solid green on power, DS, US, and online lights).  The physical desktop is connected to the Cisco modem.  I have a laptop that connects wirelessly to the modem.

It just seems to drop about once a day.  Usually unplugging the modem and then replugging it in seems to get it up again but this doesn't seem normal to be doing it everyday.  

Thanks!

socaluser, 

If your last post was made via your Cox service, I was able to locate your account and I'm not liking what I am seeing. Does the modem connect directly to the cable outlet or is there a splitter, barrel connector, or surge strip on the coaxial line between the modem and the wall? If so, try connecting the modem directly to the cable outlet. The signal levels are off and this may help bring them back into specs. There are also some power adjustments, so if the modem is plugged into a surge strip, try bypassing it and connecting the modem's power cord directly to the electrical outlet.

Hello ColleenD,

Thank you for your help.  I did post from my account and the power was plugged into a power strip.  I went ahead and directly plugged it into the wall by itself.  How does the signal look now?

It was up for two days and then went down.  Are there any additional tweaks I should do to my modem through the admin system? 


Thank you!

The receive signal levels being reported now are extremely high to the point of being out of specification.  Having a technician come out and troubleshoot further would be a good next  step towards resolving this issue.
