Question

I have a RUT240 installed in a remote area with no easy physical access to it.  It went offline about 6 hours ago.
It has been working fine since I installed it a few days ago.
Product code: RUT240
Firmware: RUT2XX_R_00.01.14.4

In the RMS portal, the mobile status is green, RSSI -51 dBm
Operator: AT&T

Why might this have happened, and what do I need to do to stop it happening again?
 

Answer 1

Hello,

Thank you for contacting.

There could be multiple reasons for that , may be power failure or mobile connection.

Mobile connection depends on multiple other parameters as well:

Always use both the mobile antennas provided in the box.

If you didn't reboot the device you can check in System>Administration>Troubleshoot .

Thanks.

Ok.  I checked the Signal Strength recommendations link, and it lists -70 dBm or better as a strong connection.  The connection listed in the RMS is -51 dBm.  

Both antennas are being used.

Unfortunately it's not very easy to physically access.   I am unable to connect to it remotely; is there another way to reboot the device as you suggest?

When you say check in System>Administration>Troubleshoot does that require physical access?

Hello,

Have you checked other parameters also ?

RSRP

RSRQ

SINR

These also matters a lot .

There is another feature in our devices that is mobile utilities, you can perform different actions on device .

Thanks.

Thank you.  Where do I find the Mobile Utilities in the RMS?  Or is it somewhere else?

Where can I see the RSRP, RSRQ, and SINR?  I'm not seeing those in the RMS.

Thank you!

Hiked out the other day to it and a power cycle fixed it.  I'm not sure why.  It *does* seem that the connection dropped when the provider shifted from Tmobile to AT&T (it's on an OliviaWireless SIM.)

I've attached the mobile signal strength graph from about 24 hours after this was power cycled.

Is there a way to get this thing to fire itself back up if it goes offline?

I've set it to auto reboot a few times a week, which may be proactively useful.  Not sure how much that'll actually help, as it was set to auto-reboot every morning when it went offline, and reboot didn't seem to do anything.

Hello,

You can see the mobile utilities in WEBGUI , but by default its enabled . You can generate a device access token from RMS . 

Please read the details here:

You can see details for how to create a token for device access here:

Mobile utilities is like controlling device or getting device info by sending text message to the device.

Thanks.
