I've had an RUT950 in place for over a year with no issues.  Continuously on the same network. 

Recently, I am having constant issues with disconnecting and needing a reboot of the router to get back online. 

What can I do to establish if this is related to the 4g provider (Three UK) or the router? 

When the network disconnects, it's also showing the time and date as incorrect.  

Thanks in advance

Occasional disconnects might happen due to the fact that your provider is changing your dynamic WAN IP address. However, if that is not the case, several steps can be tested.

1. Access your router’s WebUI. Navigate to Network->Mobile. Check your connection type, change to QMI/PPP, depending on what is currently set, press Save.

2. The screenshot that you provided indicates that the firmware version you are using is dated, so you need to perform an upgrade, as some issues, specifically related to Three UK provider were addressed in latter revisions. Firmware can be upgraded by going to System -> Firmware. You can upgrade from server or by downloading the latest version file from the following website and uploading it:  

3. Check the received signal strength, RSRP, RSRQ, AND SINR parameters. Go to Status -> Network -> Mobile. If signal strength is below -85dBm, RSRP is below -90dBm, RSRQ is below -15 or SINR is below 13dB, these are the thresholds where disconnections might begin to occur. Since your device has been in a static position for an extended period of time, the drop in signal quality might be related to some works in the mobile network itself. Could you also share where and what exactly the router is used for?

4. If none of the above points were helpful, I would like you to generate a troubleshoot file and send it to me personally. Troubleshoot is generated in WebUI System -> Administration -> Troubleshoot.

Best regards,
