While logged in to the local web interface to my Nighthawk CM2050V modem, selecting the Advanced eMTA Event Log causes a modem reset after about 10 seconds. I don’t think this is normal, but I thought I’d check here to see if this is my local problem or if this is repeatable on somebody else’s hardware. I’m currently running Cable Firmware Version V9.01.01 on Hardware Version 1.01. Any suggestions would be appreciated.Thanks,Carl

Pardon me for being harsh... But I have been quite patient waiting for my $300 modem to work with Comcast as it should! Mostly because if we want Voice support there are no choices. So, when will this all (next tier speed and eMta Log) be fixed? Are we sure the upload speed issue is only firmware and not a hardware flaw? However, I do appreciate the update. Thanks!

Can you give any more details on your information? In my most recent 2 or 3 NG tech sessions, the techs expressed no knowledge of this problem. They all wanted me to pay for an extension of my expired tech support in order to help me to address the problem. Is there any other information you can share with me in case I call NG again? Also, since I've gotten multiple contradictory responses to my questions about the Xfinity "intermittent connectivity issues" and "Netgear is working on a software update" issue, I'm still wondering if the NG tech who told me that the V9.01.01 firmware (that is currently on my system) is the solution to the problem. With so many divergent bits of information, I'm getting tired of trying to decide who's information is correct. Thanks,Carl

Did you get this information from Netgear, or did it come from some other source?Thanks,Carl

OK, I'll contact Xfinity to see if I can get their attention. I'll set aside some time tonight or tomorrow and find some nice relaxing music to calm my soul as I go through that process.Thanks,Carl

This is great to hear! I will try to contact Netgear again to see if I can get access to more information about this condition. I'm past the 90 days of free tech support, but I'll see if I can weasel my way into support without paying the $60 they asked for last time.Thanks,Carl

How about the Cable Connections and standard Event logs pages? Can you access these and then also post the data here in this thread so we can take a look?

Thanks for your quick response.

All the other pages seem to load up without problems. I tried the eMTA Event Log about 3 hours ago (generating the reset). Here are the requested results of Cable Connections and standard Event log:

Power levels are good and no correctables or un-currectables.

I see some Criticals the the ISP should look into. Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.

Not sure about the Advanced EMTA events logs. Wondering if maybe that is not supported with is modem and the ISP services.

Something to try, disconnect the modem from the ISP coax line. Then try this advanced EMTA log selection to see if the modem reboots or does something different...Reconnect the ISP coax line after checking this.

Anything connected to the phone ports?

What is the brand and model# of the wifi router connected to the modem?

Does this happen with a different browser?

I am on Hardware Version 1.01 Cable Firmware Version V2.01.03. And trying to open the eMTA event log causes the modem to reboot every time. This has persisted after modem reinitialization. Glad it is not just me...

    I called Netgear again and was able to gather more "free" information from the tech (who really wanted me to buy the additional tech support subscription). He wanted to prompt me through a reset and I told him I had already used the web interface reset, the power-cycle reset, and the hold-reset-button-down-for-7-seconds reset (from the online documents. He said I needed to do a 90-second shock reset, consisting of holding down the reset button with power-on for 30 seconds, continue holding down the reset button with power-off for 30 seconds, continue holding down the reset button for 30 more seconds while reapplying power. After this process, I should use the local user interface to set up the modem (no details given) and then contact my ISP to have the current software downloaded to me again. I'm not home right now, so I'll try this process when I get home tonight.

I can confirm that this happens on my modem as well. Viewing the event log sometimes causes the modem to reboot.

  Is there some way to report issues to netgear, without paying for support?

  When my system "always" reset when clicking on the eMTA Event Log button, I tried a direct connect to the modem from my laptop. That connection gave me the eMTA Event Log and after that, connection of my main computer through the router was able to load the eMTA Event Log without resets. After performing a "shock reset", the software had changed back to the V2.01.01 version and my eMTA Event Log requests started doing the resets again. My questions to you are "do you like to play" and "are you feeling lucky?"
  
  Later,

    I have never felt lucky with NetGear products. I have had many and they always seem fluky. I bought this because for voice and high speed comcast data, this was the only choice, then it fell off the compatibility list 😞
