I recently tried to do a firmware upgrade on my UniFi<\/a> Access points, all went well except for one AP refused to update. I tried all the usual troubleshooting steps, rebooting the device etc, but to no avail. I then found the ability to use a local cache of the firmware and thought “last ditch attempt, let’s try it”. However, to my surprise it was the fix, so may help out in your situation also! <\/p>\n\n\n\n

\n\n\n\n

Update Local Cache Instructions<\/h2>\n\n\n\n
    \n
  1. When performing an upgrade, first, try using the traditional method; going to your UniFi Controller, then clicking on Access Points on the left hand side (1), then clicking on “Click to Update” (2) in the firmware status column.<\/li>\n<\/ol>\n\n\n\n
    \"UniFi<\/figure>\n\n\n\n
      \n
    1. If that fails, (eg; it never updates), I then went through the troubleshooting steps of rebooting the device, validating connectivity etc.<\/li>\n\n\n\n
    2. Then head to the Settings (Cog Icon) on the left side bar (1), and in the options that appear in the subsequent side bar, click on System (2).<\/li>\n\n\n\n
    3. In the “Advanced” settings area of the centre panel, you will see the option to Cache the update (3). It will take a moment to download depending on your WAN speed. Once it is downloaded you can validate it has appeared in the “Cached Updates” toggle (4).<\/li>\n<\/ol>\n\n\n\n
      \"UniFi<\/figure>\n\n\n\n
        \n
      1. Now, try rerunning the update from the device list (shown in step 1).<\/li>\n<\/ol>\n\n\n\n

        These steps resolved the problem for me and the firmware update applied successfully. For good system hygiene, I would suggest removing any old Cached Updates to keep your environment nice and clean.<\/p>\n\n\n\n
