Hello,
i have 2 antenas in same place: Mikrotik RB/SXTG2 using the AP function.
sometimes one of then stop the wireless function.
If i turn off the power and turn again on all start working again.
Maybe is a conflit os channel on antennas? or there is some other issue like password atack?
thanks

try to use another software or maybe your wireless interface have something wrong

Why not place the 2 antenas in different places?

In addition, why not change the channels or change the mode of one of the antennas.
