To use a Picostation with UniFi, you have to load a new firmware onto it. From that point on it will work as a UniFi access point. This is considred to be a ONE WAY procedure – but Ubiquiti has instructions on the page linked below on how to bring it back to the stock firmware.

Step 1 – Download the Pico to UniFi firmware

The firmware to do this is found on the Ubiquiti forums in a ‘sticky’ post with the current release software.


Step 2 – Log into your Picostation

Log into your Picostations webgui as usual:


Click on the System tab:


Click on the “Update…” button at the bottom and this window will pop up:pico_firmware_upload_page-8

Click “Choose File”, select the airos2unifi.bin file you downloaded earlier, click Upload, and the Pico will install the new firmware and reboot.

Step 3 – check that your Picostation shows up in UniFi Controller

Now the Pico is a UniFi access point. Start up  your UniFi Controller software and make sure it shows up in the list of Access Points as Pending Approval

(note the icon on the far left – it reflects that the new AP is a Picostation and not a UAP)


Step 4 – Adopt the Picostation into your UniFi Controller

From this point you will want to log into your UniFi Controller and adopt this Picostation to become part of your UniFi system:

Click the Adopt button and the Pico’s ‘Status’ should change to Adopting



The Picostation is now ‘Connected’ and is working in your UniFi system.

    doesn’t work as uplink,
    only works if you ant to use as a main AP

      Exactly, if you turn off the controller the wifi radio turn off too.

  • admin

    If you turn the controller off, the radios do not turn off. You can remove the controller altogether and it will run just fine as long as you don’t use a guest network/hotspot. If you’re just setting up a basic network you do not need the controller running.
    Not sure if that is true with wireless uplink or not, haven’t been able to test it yet.

    I’ve been able to revert from Unifi to AirOS.

      How did you do that? I have one I’d like to change back to AirOS.

        Looks like the post on UBNT was updated 2 weeks ago and includes the procedure to roll it back to AirOS: http://bit.ly/157jYZQ

          Beautiful! I have one I need to revert back to being ‘just a Picostation.’

          Thanks for the link!

    My family’s home has a Unifi 2.3.9. How do I check what sites have been visited ? I am really pathetic when it comes the technical side of this stuff, so if someone can explain it to me in simple terms I would be very grateful.


  • lutfiyadi

    Steps back to airOS the link can’t open,,

    how to do?

  • Penwell

    would it be possible if i have a cloud server running the unifi controller to ssh into the pickostation or use the discovery tool to point it to the cloud server like ive done with the UAP

    • admin

      Yes there are a lot of people who run Unifi server on Amazon Web Servers, search for Unifi on AWS, you’ll find quite a few walkthroughs. I set it up once months ago but haven’t been using it and have forgotten the steps.
