Hello, 

Regarding the issue you are having there are a lot of factors that may affect LTE speeds you can refer to this link below for more details:
https://wiki.teltonika-networks.com/view/LTE_Speed_Discrepancies 

Also it is best to check if the RUTX12 is using Carrier Aggregation or not you can check it in Status > Network > Mobile

Hope it helps.

Regards,

Jerome

So it is using carrier aggregation, only within the same band and between different channels.

Updated modem to EG06ELAR04A08M4G, however on the X12 i still need to change Band selection Manual for it to select Dual under Carrier Aggregation as for the X11 it Auto detects and changes to Dual by itself.

When you have performed a firmware update, did you do it with Keep settings option enabled?

Could you try resetting both devices from factory defaults, if you did. Depending on the previous version, migration to the latest may have left some internal configurations, which might interfere with the device operation.

I just restored to factory default settings on both units and now both units can not change to Dual under Carrier Aggregation.

Was the log files i sent you able to check if it is firmware related to this release?
