Ap 5131 Firmware Update

Ap 5131 firmware update download

Just bought some used Ubiquiti UniFI AP Long Range access points for my own internal project. The UniFi came with old firmware version So first thing I have to do is upgrade the firmware to the latest version.

Basically we can do firmware upgrade of the Ubiquiti UniFI by using the controller. Add the UniFI into the controller and then adopt it. Once it is connected to internet it will automatically detect available firmware update.

However using this method seems not work. The UniFi AP disconnected several times while updating. After waiting for around 30 minutes without success, I tried to upgrade the firmware using local upgrade via SSH. Using this method the firmware upgraded successfully.

The AP-5131 access points are 802.11 a/b/g but are total hell to work on. I have serialed up to the 5131 and restored the AP to factory defaults and can access admin level through the CLI just fine. Problem is I don't know the CLI so I need to access the GUI.
