Downgrade of firmware - I read that plugging in an AP already on V10.1.1 but with the controller (ZD3050) on V9.8.2 would automatically downgrade the firmware back to the older version. It has not done so. Should it, or is there another way to use newer builds on older controllers?
The AP should automatically, downgrade itslef to the version of the controller. Please SSH into the AP and check its logs or please check the events under Access point, that should give us some information.
If the AP is connected remotely over VPN please try to reduce MTU and check.
