[PLA5236] Issue with FW V1.00(ABFB.3)C0

I am having issues with my PLA5236 after upgrading to V1.00(ABFB.3)C0, it became unreliable and slow. 5Ghz has never been excellent with the PLA5236 but for my needs was enough. I downgrade to V1.00(ABFB.2)C0 and the PLA5236 turned into its old self... "good enough"

While in V1.00(ABFB.3)C0 I tried factory reset, reconfigure, but the problem persisted, fortunately ZyXEL allows to downgrade the firmware.

Did  anyone else have this issue? Do you have any recommendations?

Thanks
