I have just purchased a new Teltonika RUTX11 router. I have one SIM installed in SIM 1 tray and set as the Default SIM. It is a Three Ireland Mobile Broadband SIM.
With the shipping Firmware, RUTX_R_00.02.01.1, the router functioned in its default state.
I have tested the following adjusted configuration which works well:
- SIM Card Setting/Service Mode set to: 4G (LTE) Only
- Band Selection set to: Auto (it also works with bands B3 (800 MHz) and B20 (1800 MHz) selected which are the 4G bands used by Three in Ireland)
- Network Operations: set to Manual and selecting Operator Code 27205 (Three Ireland 4G)
- Mobile Configuration | MOB MOB1S1A1
- Auto APN: OFF
- Custom APN: internet
- Authentication: NONE
- Pin: 0000
I should add here that when Auto APN is selected the SIM connects as expected when using the shipping Firmware RUTX_R_00.02.01.1.
However, when I update to the latest Firmware Available on Server, RUTX_R_00.02.03.4, the SIM fails to connect. Even when I make the settings that worked (above) with the shipping Firmware, RUTX_R_00.02.01.1, the SIM still refuses to connect.
I have had the SIM replaced by Three and this did not improve matters – the SIM still refuses to connect.
I can only assume there are additional settings that need to be adjusted / set to allow the SIM to connect with the Firmware update (RUTX_R_00.02.03.4) that do not appear in the older shipping Firmware?
The newer Firmware appears to have a number of additional options not present in the shipping RUTX_R_00.02.01.1 version which I note is now not available on the RUTX11 support page – only Firmware Version RUTX_R_00.02.03.4 is now available.
I am at a loss as to what to try next and I please need assistance to solve this frustrating issue.
Thank you in advance for any and all help and suggestions, or to share feedback from users who have encountered a similar issue.
