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 thoug...

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?
