RUTX50 Failover or Load Balancing?


@AndzejJ I need some advice. I struggle a lot with performance (speed and quantity of data). I like to share my current setup of my RUTX50 router. At this stage I have just 1 sim card but I am planning a second to improve the performance.

This is how I have setup my network. Its both used for business and pleasure:

A short explanation:

  • Internet is provided via one ISP (SIM 1) (5G NSA, NAT).
  • I have WiFi on for both 2.4 and 5GHz
  • On LAN Port 1 I have a Rasberry Pi4 running Home Assistant managing home automation as well as some business automation.
  • On LAN Port 2 I have a Tp-Link base station for the Powerline network with 10 AP’s
  • On Port 3 and 4 I have Tp-Link routers connected serving areas where the Powerline fails.

With exception of one router they are all configured under the same SSID and Password.

The wifi picks up about 10-11 clients.
The Powerline would handle 60-70 entities/clients.
The routers another 10 or so on a good day.

When I will start using a second Sim card what would make sense, Failover or Load Balancing and why?

In terms of performance what would be the best setup for the LAN configuration (currently static with DHCP server enabled, lease time 24hrs).

Can make MultiAP make a difference as well?


Thank you for your query.

Load balancing allows you to use multiple WAN interfaces to help to handle various requests that come from different clients. Because the device has only one modem, you can not utilize the two sim cards simultaneously, so adding a second sim card won’t allow you to utilize this feature. If you wanted to utilize this feature, I would advise you to get another WAN service such as a Wired WAN or the Wireless WAN.

If you do add the second sim card it will allow you to utilize the Failover feature that ensures constant internet to your clients so that when the Sim1 goes down the second one will be activated and continue to provide internet. Unfortunately, the Failover feature would not have any effect on the total throughput of the device. More information on how to setup can be found here RUTX50 Failover - Teltonika Networks Wiki (

Regarding DHCP, it is usually best practice to put static IP addresses on your routers, access points, and switches. For clients to use DHCP.

Multi AP wouldn’t be applicable in your setup since you do not have multiple Wi-Fi WAN sources available. The Hotspot feature will provide authentication, authorization, and accounting for the network considering the number of clients that connect to the network. It most importantly gives an option to limit download and upload speeds. More information about how to set up and the different configurations can be found here RUTX50 Hotspot - Teltonika Networks Wiki (

Lastly, if additional WAN sources wouldn’t be available, you could try offering traffic shaping (SQM + QoS), which could help in controlling the existing traffic: RUTX50 Traffic Shaping - Teltonika Networks Wiki

@kennedy.kurui Thank you for your explanations. I will explore the options one by one and see how I can make them to good use! Appreciated!
