Hello @Drakkonian,
Thanks for reporting this issue to the TP-Link community!
I have feedback on this updated issue of EAP610-Outdoor to the engineer for further investigation. I will keep you updated on any progress.
For now, please revert the firmware back to EAP610-Outdoor V1 1.1.3. You may downgrade the firmware through two methods below:
1. Go to EAP Details window, Click on Config > Manage Device > Custom Upgrade, and click on Browse to upload the 1.1.3 firmware version. (Please confirm the account you used to log into the Controller is the Main/Master Administrator.)


2. You can also choose to Forget the EAP to get it back to the Standalone page via Config > Manage Device > Forget. Then upload the file on the EAP web interface:

After upgrading, adopt the EAP again on the Controller.
If there is any stuck issue during the upgrade process, you may try the Firmware Recovery to fix it.
