Hello

I am using RUTX12 model.
Firmware uses the latest version 07.01.4.


I connected two SIMs to test the load balancing function.
The ratio was set to 5:5, and the data was set to 10Mbps.
When you check the traffic in real time, only one SIM is flowing.


How can I set it up for load balancing?


If the SIM carriers are different, is there a problem using the function?

Thank you.

Hello, 

Before configuring load balancing. Can you confirm that the other SIM connects and receives traffic?  

With a ratio of 5:5, and a data limit of 10Mbps for each SIM card. You should have a total speed of at least 17 Mbps. 

There should be no problem in using two different SIM carriers, nor that the interfaces used are both mobile. This is because the RUTX12 has two modems and they can work at the same time. 

In case you have any doubts about the configuration. I leave you this link that explains the load balancing configuration and its different characteristics.

Router transmits data at 10Mbps.

Two SIM cards are connected and load balancing is configured, but only one SIM card detects 10Mbps of traffic.

The situation we want is...

If SIM1 and SIM2 operate normally at a ratio of 5:5, they must detect traffic of 5 Mbps on SIM1 and 5 Mbps on SIM2.

In this case, it will be necessary to configure Traffic Shaping for each Mobile interface. To do this you must enter Services -> Traffic Shaping. You must create a rule for each mobile interface limiting it to 5MB each. Here is a link with more information about this configuration.

After that, you should have 5 MB of output load balancing for each provider. To check it reboot the router (This will clear RX/TX packet counter data on your network interfaces). After you have regained connection do a speed test 2-3 times. Make sure other network interfaces with internet access are disabled on the computer. Check the interfaces information on your router and see how many RX packets were downloaded through each interface.
