Initial settings for the Teltonika RUTX12 WiFi/LTE router
Teltonika RUTX12 router is operated via extensive web interface, available on any browser after logging in. The login data given by the manufacturer for the first logging is login: admin password: admin01. Of course, for security reasons, they have to be changed, which is also enforced by the system.
The first configuration can be done via the included cable connection, or WiFi, which has the startup settings written on the sticker of the device. Once registered, the TELTONIKA RMS also allows extensive management, also accessible from outside the local network.
The English interface is exceptionally clear and legible, despite the many options for entering settings or checking device status. It is based on a hierarchical menu and tabs in a pleasant to the eye bright colors.
Registering a device in RMS requires an Internet connection, creating and activating an account on the manufacturer's website
, or logging in and adding the device. Make sure that the RMS setting on the router is not disabled
, because then the RMS cannot be used. If RUTX12 router connects, RMS status will be marked as online
The registration process is simple and relatively quick, and the range of remote support is very broad.
Notes on configuration and management options
The device has rich management options thanks to the RutOS operating system used. It supports for example eight types of VPN, Dual WAN, advanced protection against attacks, MQTT, many security features, such as Ipsec, PPTP, L2TP, Stunnel and GNSS tracking, and many others. The system provides the possibility to write custom scripts to help implement individual applications, as well as install additional packages to extend the basic functionality. The purpose of the router to support IoT is intentional, but some people may miss more inputs and outputs or a physical RS232/435 port. Teltonika RMS, or Remote Management System gives full information and statistics, remote configuration or even access to CLI. The manufacturer has set itself the goal of providing a device with high reliability, allowing to provide uninterrupted connectivity to the Internet.
Test of RUTX12 device from Teltonik - conditions
We performed the speed tests using WiFiPerf software, and the speed test server was iperf3 software. The conditions were similar to the tests of the other devices in the series of experiments we conducted. A three-storey building with the device located on the ground floor was used to prepare a sitemap. To make a signal map we used AirSurvey software. For correct reading of the signal levels it is worth to pay attention to the color legend at the bottom of the picture. The device on the "ground floor" was connected to the switch via 1 Gbps Ethernet port.
How did the Teltonika RUTX12 dual-band router perform in tests?
Measurement with radio spectrum analyzer of Teltonika RUTX12 device showed relatively poor performance of WiFi transmitters. The signal power level at the time of saturation of the link in the direction of transmission from RUT12 showed considerable power fluctuations.
WiFi network speed tests unfortunately did not turn out too well, because in points 5 and 6 network was unavailable. When trying to perform the measurements it turned out that the test device has too weak range to establish a stable wireless connection.
For the remaining points, the connection was fairly stable given the obstacles overcome, as shown in the table below.
Measurement point 1 - Download 326.87 Mbps / Upload 494.64 Mbps
Measurement point 2: Download 360.31 Mbps / Upload 439.57 Mbps
Measurement point 3 - Download 353.40 Mbps / Upload 214.98 Mbps
Measurement point 4 - Download 29.53 Mbps / Upload 33.74 Mbps
In addition, we examined the possibilities offered by the LTE connection RUTX12. In the test conditions, in comparison with other LTE devices, the achieved throughput and other parameters of the connection in the Play network were very good. The computer on which the test was conducted was connected to the router wirelessly.
Both the indicator lights of the device and the web interface allow you to check the strength of the mobile signal, which facilitates optimal antenna alignment. Dual SIM option makes it possible, for example, to use cards of two different operators.
