Mikrotik SXT not Connecting to any Ubiquity AP after firmware upgrade

Hello , This is Basha and I have been using mikrotik SXT’s and Ubiquity Devices for a long time. after upgrading my SXT to later than 6.36.4 bugfix or stable 6.34, my devices does not get connected to ubiquity AP’s only, Mikrotik AP’s were fine. I have tried downgrading the firmware and i found it was connecting with 5.26 and 6.30 etc.. I have tried set the wlan mode to station pseudobrige, station wds etc., but no use in newer firmwares. I am asking that, why is this happening after recent firmware upgrade. I also tried flashing directly with a newer firmware, still no use. Tried changing the channels and frequencies band to A or A/N in client.


My device configuration’s are as follows :

Ubiquity AP : 192.168.1.x
Wireless Mode : 802.11n
SSid : test (not hidden)
Security : WPA2-PSK - xxxxxxxx
No other configuration was touched.
Station : 10.11.16.x
Dhcp was disabled
Configured in bridge mode
remaining configuration same as default.


Note : I tried changing config but no use and i also have tried downgrading AP’s firmware but it was not the AP’s issue.


Sorry for my bad english.
