Sir, I have installed a ubiquity Rocket M5 with 19dbi antenna, and airmax is also disabled and the firmware version of AP is 6.0.3 (XW) (tested even with XM Devices) . Mikrotik clients not connecting only after firmware upgrade in Mikrotik SXT from legacy 5.26 to latest ones or even tried flashing manually but didn’t work. After several days of trials i found out that i cannot connect my sxt if it is upgraded to 6.37.1 or later. I can upgrade maximum version up to 6.36.4(bugfix). If i upgrade to newer than 6.36.4, it wont connect in any mode, i mean to say station wds/ station pseudobridge. It just keeps showing searching for network and it won’t connect. I am facing this issue with the newer firmwares only with every mikrotik client. Please Help me.
Here are some screen shots of my Ubiquity AP config.
