Either
The router selects a band (B20) and does not connect when there is an alternative valid band (B1) available.
Or
The router selects a band (B20 - 20Mb) that is considerably slower connection than an alternative available band (B1 - 75Mb).
I have to manually select the band in network>mobile>connection to either obtain a connection or faster speeds.
Hi…
LTE Band 20 (800 MHz DD) offers good coverage and penetration, enabling widespread LTE services, especially in areas with dense infrastructure, with throughput ranging from 5 Mbps to 100 Mbps and peaking up to 300 Mbps in optimal conditions.
Your RSSI, RSRP, RSRQ and SINR are very poor.
LTE Band 1 (2100 MHz) offers a theoretical maximum downlink throughput of around 100.8 Mbps, with a bandwidth of 20 MHz and 64 QAM modulation.
I understand this but sometimes the router only tries to connect on B20 showing the Operator as N/A, see screen shot 1, with NO internet connection. I have to manually select band B1 to obtain an internet connect as per screen shot 2. This is not logical, if a connection is N/A then surely the router should try the alternative band and obtain an internet connection.
The ability to select a band automatically based on speed would be desirable.
Agree… 10000% with you…
Today… I am using an external antenna to get better LTE signal.
I use the router in a van with an external antenna and travel extensively in the UK. In some locations I have to obtain an internet connection by choosing a different band manually which is illogical.
In other areas, even though signal strength in excellent on both B20 and B1, I have to manually change the band to B1 to obtain quicker internet speeds.
Are you, also, using the external WiFi WAN of the device?
Maybe this kind of antenna will allow your device to get a better signal. (LTE/WiFi)
Sample: POYNTING PUCK-4
I have the Teltonika external puck. However, this is irrelevant as I have a signal but am having to manually select a band in order to obtain a connection or increase speed.
For example, where I am at the moment the router tries to connect to B20 but fails and that’s it no connection. I therefore have to select B1 manually to obtain a 15Mb connection.
Yesterday, in a different location with excellent reception, the router connected to B20 to give a 20Mb connection. Manually swapping to B1, also with excellent reception, gave me a 75Mb connection.
Hello @hejhog,
Apologies for the delayed response.
Could you please confirm if your device is running the latest 7.13.3 RutOS firmware? If not, you can download it from this link and update your device.
Once the update is complete, please check if the issue persists and let us know.
Thank you.
Best regards,
Hello,
Thanks for the update. I am not in the specific area where I noticed the issue. However, I can see from my present location that the mobile channel is switching between B1, B8 and B20 therefore this issue may have been resolved.
Many Thanks,
Shaun
