Modem is not forwarding all UDP packets

I have a Teltonika RUTX11 and we are trying to send UDP packets and we are getting poor performance. In a minute we are sending 15K packets (small payload) and unfortunately tcpdump at the modem only registered 2K.

Any tweaks I can do to improve the packet transmission performance? Running Speed Test, I am getting 18Mbps download and 23 Mbps Uplink.

Hello,

Apologies for the late response.

Could you please specify the RutOS firmware version your RUTX11 is currently running? If it is not the latest one, 7.11.3, please download it from here https://wiki.teltonika-networks.com/view/RUTX11_Firmware_Downloads and update your device.

Also, let me know how the RUTX11 gets internet access. If it’s through Mobile WAN, please share a screenshot of the Status → Network → Mobile page from the WebUI.

Best regards,
