I have 2 WAP121-A-K9 WAPs with firmware 1.0.2.3 that I want to upgrade to 1.0.6.2. The first WAP upgraded without a problem. The second will not upgrade, I get the error message: Firmware upgrade has failed. Please ensure that valid entries are specified in the required fields.
I know the firmware file is fine since it works on the first WAP. I have reset the second WAP to factory setting and tried and it fails with the same error. I also tried firmware 1.0.4.4 and it fails. Any ideas how to get this to upgrade?
