Just wondering what the Blueout and Brownout indicators mean.  When should they say yes and when should they say no and what do they indicate?

Hi Brain,  
 Please let me know where you are seeing brownout and blueout modes.  Do you have the new WiFi Exede Modem?

I also see that in Tria status on modem web page and mine says Brownout mode enabled-NO and Blueout mode enabled-NO. Also curious about what that is.

As far as I know it's been there for a long time and you're not the first to ask, but i never saw an answer.

Well normally a brownout means reduced power to an area, like in LA in the summer when that happens due to too many A/C running, lights dim, electronics turn off, etc... so perhaps it means the tria is not receiving full power.

Blueout is a disturbance, usually a nuclear explosion, underwater that causes noise that temporarily interferes with sonar. So perhaps Blueout here would be something that temporarily interferes with the tria getting signal (like solar flare, covered in snow, some jokester put foil over it, etc...)

Since no one at Tier 1 or Tier 2 support has any idea of what this screen looks like or is either (called on unrelated matter), here is a screenshot of mine.

Modem just restarted so it does not show Brownout mode enabled as Yes yet, but it will after a little bit.

Screenshot of Brownout Enabled.  Would love to know what this is as it seems like it might help the tech coming out troubleshoot the issues I am seeing.

Any chance of getting the answer to this prior to 2:00 PM today?  Tech scheduled to come out and would like to know if it may help point to a particular problem.  Still says yes btw

Most likely brownout and blueout will have no bearing on your problem. As has been mentioned, this has been asked before and we never got an answer. Your tech will probably not know either. Please post if you find out what it means. I see cable resistance is red. On the modem tab, there will be a number for resistance. What does it say? I needs to be less than 5.  How long is your cable run? If over 150 ft, you should look for alternative way to run it. Look at your cable markings and see if you see either "sc" or "ccs." "SC" is good. If you see CCS, have the the tech replace the cable. "SC" = "solid copper." "CCS" = copper clad steel.

Jim -

My normal cable resistance after it was fixed that last 2 times was 2.5 Ohms.  It currently bounces between 3 and 4.5 Ohms.  Attenuation jumps around from as low as 8 to as high as 35.  

For proper performance it is supposed to be under 3 Ohms.  This is confirmed with Tier 2 suppor and a couple of techs I have spoken with.  Length is maybe 85' to 100 ' including the grounding block and the piece of cable to the modem.

All cabling is the correct type.  Waiting on service tech now.  Will update soon.

Alright.  Cabling replaced still 3 Ohms.  Replaced the Tria and we are down to 0.5 Ohms.  Seems it may have been a bad Tria.  Tech didn't know what this meant either, however after replacing the Tria the Brownout Mode Enabled is now set to no.

As a  SWAG...I wonder if Brownout Mode means the TRIA is receiving insufficient voltage and is operating in some compromised mode to accommodate the lower supply voltage?

I suspect that is the case, JEP since that's normally what a brownout is when you are talking electricity.
