I have a RBM33G with RouterOS version 6.46.5.
I have installed a module R11e-2HPnD on the central slot and a 4G module from Sierra Wireless on the other slot.
The problem is: sometimes, when I reboot the router or when I power down/up, the "wlan1" interface is not present.
After some reboots, it comes back visible.
Is there a way to check the firmware version of the wireless module?
Could be an incompatibility between RouterOS version and module?
The wlan1 interface must be created automatically at startup, right?
