I decided to reboot my RUT955 (FW: by the command system > reboot

After a few minutes, I noted that the access to internet was disabled (I did ping

I also observed that the RUT955 was in a loop (I looked at the signal strength leds): every 5 minutes a retry was done.

Then I looked at the crontab:

*/5 * * * * /etc/init.d/operctl restart

Finally I turn off the power supply and turn on after a few seconds and everything was ok.

I am disappointed because my RUT955 will be installed at 200km in an isolated location. Nobody could turn off/on the power supply.

Any explanation ?

I would suggest upgrading you Firmware version to our newest, you can find it here: https://wiki.teltonika.lt/view/RUT9xx_Firmware

For unexpected losses of connection I would also suggest you to use our Ping Reboot function, you will find more information here: https://wiki.teltonika.lt/view/RUT955_Auto_Reboot

Could you generate a troubleshoot file and send it to me via Private Message? You can do it in System > Administration > Troubleshoot > Troubleshoot File > Download. Thanks.

Hi I have the same problem.

When I do  /etc/init.d/network restart

It reconnects and I have a working deafult route again.

This error happens even at a fresh boots sometimes.

I would not recomend using RUT955 in any important things or remote location until they fixed all these connection problems.
I been having soo much problems latly, and I am using the latest firmware there is to update with.

I made a script now to help with this problem, not a fix but better then waiting for a fix..

You need some basic skills of linux to use it.

login to your RUT as root

create a file using vim (or other text editor in RUT)
paste all this and then chmod +x yourfile


default=`/sbin/route | grep -c default`


if [ ! -f "$tmpfile" ]; then #create file if missing.

        echo 0 >$tmpfile


trigger=`cat $tmpfile | grep -c error`

if [ $default == 0 ]; then      #0 Error no default gateway

        echo "error" >>$tmpfile

        echo "Missing default gateway"


        echo 0 >$tmpfile


if [ $trigger -ge 3 ];then      #Too many errors

        echo 0 >$tmpfile

        echo "Rebooting, missing default too long"



THEN you can add an entry in crontab running that file every 5 or 2 mins and after some fails it will reboot your device for you.
(ex   */5 * * * * /usr/mystuff/chknetworking )
This script only check for a valid default route, but I think the problem with RUT devices it the poor WWAN inplementation/driver layout on board what ever..

Hope it helps you.
