MR1100 fails to reestablish the connection after the hang up

[mjeddajev]

MR1100 - Dear netgear support, I'm having problem with connection - due to my operator restrictions, session is disconnected  every hour, and solution is to switch data field OFF apply and then put data ON and apply in cellular settings. Other devices with the same operator managing such disconnection without any problems.

Exactly the same issue as was described https://community.netgear.com/t5/Mobile-Routers-Hotspots-Modems/Netgear-Nighthawk-M1-data-connection...

Unfortunatelly, that discusssion is closed, so I have to create the new one.  Solution with pythion script is not applicable because script fails to pass authentification ("Failed to authenticate, incorrect password?"), probably because my firmware is NTG9X50C_12.06.11.00 and not the one script was created to (NTG9X50C_12.06.02.00)

@Mexoh1To7k, Could you please help me at least with the new script?

Sure.

For the script to run you only need the requests module which you'd usually install with pip in this fashion:

pip3 install requests

I will make a new version of the script to remove this dependency.

@Mexoh1To7k, Could you please help me at least with the new script? 

[mjeddajev]

Thanks a lot! Great job! Works like magic from the very first execution! You saved my quarantine and my peace of mind!

No need to bother yourself with rewriting script to avoid requests usage - anyone who managed to install and run python script will manage to install requests too.

Now I will keep my finger crossed for Netgear firmware with this issue fixed.

@Mexoh1To7k 

Thank you for this script. I used it but my mr1100 was still disconnected. Probably because I run it 

with

python script.py ip password &

?

Anyway. Would you mind if I use parts of your code to build a script that periodically reconnects after 24 h to avoid the forced disconnecting of my provider in the first place. I never wrote other than normal bash script so this would be a more as solid base to do so.

[Mexoh1To7k]

@maroc84What does the script says when you run it?

Also, you may need to check your firmware's version and use the appropriate script.

The script monitors for disconnections to reestablish data regardless of the periodicity of the disconnections. Whether they happen every 6, 12 or 24 hours, the script will re-anable data within seconds.

Yes, you are free to do what you want with the script.

@Mexoh1To7kI tried several times to reply again but my posts disappeared. I don't know why.

So I try again without code.

My Model is from europ (1100-100EUS)

FW: 12.06.11.00

I ran your script again the last two days over night without success. When I manually uncheck mobile data in the mr1100 while running the script it does its job but not when the connection gets cut by the provider over night.

That night it was disconnected an your script didn't work.

I manually killed the script, started it again that morning  (about 5:30 am). As far as I can tell it stucks on  "Data appears to be disconnected, reconnecting..". till my ssh connection was timed out.

I have a external server monitoring my connection status. So I can tell that my router was offline from 5:23 to 8:24 am.

Could you provide a solution to get a working logfile from your script?

I tried with

python script.py IP PASS >> logfile

But this did't work and I have no clue how to use the logging module in your script 😉

[Mexoh1To7k]

@maroc84Is the Data button checked or unchecked when you are disconnected?

The script appears to correctly detect that Data has been disabled. Perhaps it fails to re-enable it.

[maroc84]

Sorry for my late reply.
So your script was working fine. I found out I ran my MR1100 in bridge-mode (IP-Passthrough) what wasn't working correctly therefor I could reach the IP of it without problems. This may be the reason the script couldn't restart the connection if lost.
 
After setting the MR1100 to normal router-mode and my router behind it as a IP-client it worked flawless.
 
So other news. Yesterday I got a firmware update to 12.06.12.00 and had no change log so I disabled your script for testing purposes and YEAY - without your script as active service on my raspberry py 4 the connection was rebuild after provider-site disconnection!
hopefully this wasn't just some strange mistake 😉
