SXTsq 5 ac - missing wlan interface

RouterOS General
1

Hi,
I have a problem with two STXsq 5 ac - there are no WLAN interfaces.
Devices are new, and the problem is from the beginning. I’ve already tried updating to the newest ROS(7.6), stable(6.49.7), netinstal, and configuration reset but nothing has helped.
When booting, log shows the following:

DefConf gen: Unable to find wireless interface(s)
error while running customized default configuration script: interrupted

I’ve added ‘interface’ and ‘wireless’ to the log, but they don’t have any log entries.

I include a screenshot from WinBox showing the problem:

Do you have any idea what else I can try?
Thanks for your help

Hi,
so nobody has any idea? I’ve hoped that it can be solved without returning to the reseller.
So I will send it back, hoping they will excache those antennas.
