Hello,
There are several disconnects, but they are very brief and should not be related to increased data consumption.
Active connections list do not indicate any unusual hosts other traffic RMS either.
If this becomes regular occurrence, for a more detailed connections and traffic data, you could install Darkstat package with the following SSH commands:
- opkg update
- opkg install darkstat
- /etc/init.d/darkstat enable
- /etc/init.d/darkstat start
Then open your browser and enter routers IP with added 667 port. For example:
Host section can provide quite detailed statistics on each IP address monitored by the application.
Alternatively, you can install TCPdump from Services -> Package manager and enable monitoring for mobile wwan0 (mob1s1a1_4) interface and download the file later from the same page.
Data here should provide sources of data consumption.
I also see that you have failover functionality enabled, yet the device has only mobile WAN available. Could you disable it in Network -> Failover page in the WebUI?
Best regards,
