Dear @SUPAJ,

I recently bought an EAP225(US) Ver3.8 Access Point. I downloaded what I thought was the most recent firmware here. However, since I upgraded the WIFI range and performance seems to have degraded. My outdoor camera which connected fine before upgrading can barely connect now. Unfortunately, I did not take a note of the firmware which the EAP225 came pre-installed with before I upgraded. There are 3 firmwares at the link I posted above. I have tried all with the same results.

 

There is also this link below with firmware for V3 of the EAP225.

 

Now I'm confused. They both say US in the URL. Which link should I used? 

For EAP225(US) Ver3.8, the following firmware download link is correct. ( V3.8 = V3 )

Is your EAP225 configured and managed via Omada Controller or via Standalone web UI?

Do you have any advanced features such as Airtime Fairness configured on the EAP225?

May I know the model number of your outdoor camera?

If possible, you may factory reset the EAP225 and configure the basic wireless settings with WPA/PSK-AES security for a try.

If your concern is resolved, I'd encourage you to give feedback to the community so others can be confident of the solution.
