Step 3. If you selected HTTP/HTTPS, select browse to locate the firmware you wish to downgrade to. A list of downloadable firmware for the WAP121 can be found here and the WAP321 here. After selecting your firmware version, go to Step 6.
Step 4. In the Source File Name field enter the name of the file to be loaded on to the device.
Step 5. In the TFTP Server IPv4 Address field enter the IP address of the server you will be taking the firmware from.
