I have two R500 APs running 200.1.9.12.62 in Unleashed mode. I want to upgrade them to the most recent AP firmware. They have internet access, but clicking the "upgrade" button tells me that the server cannot be reached or the file not found (no indication of what server or what file). The documentation has screenshots showing a Local Upgrade option and I've downloaded the latest firmware for the R500 (200.7.10.202.127) but I do not have a Local Upgrade option on my admin portal.
How do I upgrade this when the automatic upgrade fails and the local upgrade option simply doesn't appear?
