I have tested the same SIM card in my RUT955 and a simple TP-Link M7350 that cost 50 Euro. Guess which one has better connection? Yes, the TP-Link doubles the speed of the RUT955. How is it even possible? What is wrong with the RUT955?
The speeds can vary between different devices due to various factors, including hardware differences. However, here are some suggestions:
Navigate to Network → Firewall → General and ensure that 'Software flow offloading ’ is enabled .
Also, ensure that the mobile antennas are properly attached and the signal stregth and quality is good.
It is also possible that the issue you’re experiencing may be related to the choice of frequency bands.
In some cases, the other router may select a different band than the RUT955, which could lead to improved download and upload speeds for your specific situation. Let’s say the RUT955 connects to a particular LTE Band that might not offer the best speeds in your area. However, the other router might have its internal logic that prioritizes a different band or, for instance, it might not support the band the RUT955 is connected to, and in such cases, it can opt in for a different band.
To clarify, the modem itself and its software make the decisions on which band to connect to. Of course, it takes into consideration various other factors. In most cases, the modem selects the cell tower and uses frequency bands with the strongest signal. However, the strongest signal doesn’t always guarantee higher speeds due to various factors such as tower and band overload caused by other mobile devices.
It’s important to note that the modems inside the RUT955 are not developed or manufactured by Teltonika, so the choice of bands depends on the modem’s decision. Nevertheless, there are few things you can do to improve the situation.
One suggestion is to limit the list of allowed frequency bands to the same bands supported by the TP-Link. After making this adjustment, perform a speed test to determine if the speeds have improved.
To configure the frequency bands, go to Network → Mobile → General . Set the band selection to manual and choose the desired frequency bands.
Additionally, you could experiment with different bands to find out which ones offer the best speeds in your specific case. Unfortunately, I can’t recommend specific bands as this depends on various factors such as your environment, mobile operator, tower loads, etc. Therefore, I suggest trying different bands and observing their performance.
Thanks for your reply!
Is there an easier way to find out which bands are the best at any given moment?
Not really, but you can check what bands are available in your area and try those.
There is a website here where you can find cell towers and bands that they offer. So you can find the tower near you and see what bands are used. You can also execute the following commands from the router to see the serving, and neigbouring cells, respectively:
- ubus call gsm.modem0 get_serving_cell
- ubus call gsm.modem0 get_neighbour_cells
To determine the suitable frequency bands in your area, check the available options and give them a try. You can find information about LTE frequency bands here. Generally, lower frequency bands provide better coverage but slower speeds, whereas higher frequency bands offer faster speeds but may have less coverage. Keep in mind that higher frequency bands might also be overloaded with other devices. To find the best fit for your specific location, it’s recommended to conduct your own tests.
Thank once again!!
