Hi @jelyons
Welcome you to our community
In order to troubleshoot your issue, could you please share with me some information as below:
-
Has this issue happened before? Or is this the first time?
-
Is this issue happens only with band 48 or all bands?
-
Please upgrade to latest firmware for your EM7411 module following the link below, then recheck if the issue still happens in this case

You can refer to Section C - Testing on page 72 in the link below for the test procedure
AirPrime - EM7411 - Product Technical Specification
Thanks,
Jerdung,
Yes followed the steps on Page 72 see attached .txt. Looking into the firmware on our side and what is available to update with . It looks like the “AT!DALTXCONTROL” wasn’t introduced yet for the current firmware I have on the EM7411.

Hi @jelyons
I see that you are using old Release 16 so please upgrade to Release 20 which I provided in previous comment then recheck if the issue is resolved in this case.
Thanks,
