[AZ] degrading service

That 34db SNR is definitely low for that signal strength.

That log info shows nothing except a normal modem bootup log.

If the 5120 is over 3 years old I would definitely upgrade to a D3 modem. And all of Mesa should def have D3. Even if D3 isn't live you can still use a D3 modem.

oops, forgot to update my location info, I'm not in mesa anymore, paradise valley.

Yeah that was what I was afraid of with the log, it seemed "okay" to me. The issue is that it is rebooting on its own and the log file doesn't seem to be big enough to hold the errors it might get before the log.

What do you suggest for the SNR issue?

Also, here is an updated log (this happened a bit after the log above)

Now its doing it again...hasn't rebooted yet, but pretty bad packet loss and my SNR is jumping between 29 and 35dB.

Well this is silly

Well seeing as you mention your SNR jumping between 29-35db, it sounds like it may be time for a cox tech visit to your place to check over things. Since when your SNR is at its best at 35db, its only meeting cox's minimum requirements for SNR. Also your upstream power level is rather low at 38db to me, for the simple fact where you live, and the warmer temps there. Because the upstream power level only goes up the warmer it gets outside.

Also if none of the AZ techs pop in your thread by tomorrow, you can send CoxTech1 a PM he should be back on here tomorrow. Send your modems mac# to him, and he will be able to look over things from his end. He will also probably mention a tech visit needed to get them signal levels better. So see what he can find out for you, and take it from there. I also recommend thinking about upgrading your modem to a newer D3 modem, as I told someone else recently. Yes these older D2 modems are still on cox's modem support page. But that doesn't mean much, because these older D2 modems may not play very well with the newer D3 equipment cox has put to use. To provide better, and more reliable service to you.

Thanks. I think it might be time for a visit to. I hate when they come out, last time they came to "run a cable" and ended up NOT doing it because the building would not allow it, and charged me anyhow.

During the summer when it was 115*, it worked fine. Its 68* now...so...not sure if that has anything to do with it. I'll think about upgrading to a D3...money is tight so that won't happen soon.

So...I decided to run down to the cox store before it closed and picked up a DCP3010. All 4 channels lit up.

Downstream
Power Level Signal to Noise Ratio
Channel 1: 2.2 dBmv 39.4 dBmv
Channel 2: 1.5 dBmv 38.9 dBmv
Channel 3: 1.7 dBmv 39.0 dBmv
Channel 4: 1.9 dBmv 39.1 dBmv

Upstream

Power Level
Channel 1: 39.7 dBmv

Speeds are back to 20/5. Looks like my 5120 was deeead.

This thing has firmware from 2009 though; the tech on the phone said he had new stuff but was unable to push it to my modem for some reason.

Current Software Revision: dpc3010-v302r12901-091119a
Firmware Name: dpc3010-v302r12901-091119a.bin
Firmware Build Time: Nov 19 2009 22:12:51

I'm sure there is something newer than that around.



Thanks for the help by the way.
