Omnitik + RB411 Reboots when SXT connected using station-wds

greetings all,

we have the following setup with 411+ omnitik + SXT
it seems to us something might have caused loops, where Rb411 reboots everytime SXT was connected using station-wds mode.
(RB411 act as backbone)

we have other similar setups using rb433Ah and rb411, also rb411 and rb411AR, all of them have no such problem.

the only mode we can connect the SXT without causing reboots is station-pseudobridge, which we don’t prefer, since we need transparent bridge in our network.

all device is running ROS. 5.21, and is properly powered.

any advice would be much appreciated

Cheeers!
