UniFi USG link dump

Posted by jpluimers on 2021/10/04

I wanted to setup a UniFi USG (Ubiquiti Unifi Security Gateway) with round robin multi-WAN and incoming port forwarding on both WAN connections.

Quite a few links were the result:

Adoption was another headache. Some links on that too:

If you end up in a cannot adopt state, then a reset is the only practical way to go:

MikroTik RB960PGS hEX PoE powering PoE devices: ensure you get a 48V power supply

Posted by jpluimers on 2021/08/24

By default, the [WayBack] MikroTik RB960PGS hEX PoE comes with a 24V power supply.

Most PoE capable devices cannot be powered by 24V but need 48V. I wrote about this before in the midst of the long post Linus Torvalds – Google+: Working gadgets: Ubiquiti UniFi collection (and a whole bunch of Unifi/Ubiquiti/Ubtn links)

So now I re-mention it in a much smaller post so it easier to find back, and a few links to Power over Ethernet – Wikipedia, where especially these bits are relevant:

  • The PoE Standard implementation for 802.3af (802.3at Type 1) “PoE” requires DC 44.0–57.0 V.
  • Of the PoE Non-standard_implementations, some common Passive specifications include:
    • 24VDC 0.5A 100 Mbit/s or 1 Gbit/s
    • 24VDC 1.0A 100 Mbit/s or 1 Gbit/s
    • 48VDC 1.0A 100 Mbit/s or 1 Gbit/s
    • 56VDC 1.0A and 2.0A 1 Gbit/s (used for 45W+ load point to point microwave and millimeter band radios

The 24V is what MikroTik sticks to with their default power supply.

Updating a Unifi Controller (either a Cloud Key, or a local installation like a VM)

Posted by jpluimers on 2021/07/27

Note that by now, Unifi Controller is usually named Unifi Network Management Controller (somewhere in between it was called Unify Network Controller).

You can either run a local installation on a Linux box (usually Ubuntu), for instance the CloudKey ESXi Appliance, or from a Cloud Key (if you do, do not get a version 1 Cloud Key; too much SD card and other hardware trouble)

Steps to update both the Unifi Controller Firmware (Cloud Key only) and the Unifi Controller software (both Cloud Key and local installation) are below.

I am assuming that is the IP address of your Cloud Key, and for brevity, I included few screenshots, but opted for URLs.

Devices steps

  1. Logon to your Cloud Key at
  2. Go to the devices page
  3. Ensure the filter is “APs” (either through the dropdown when your tab is narrow, or the button when the tab is wide)
  4. Press the “Start rolling update” button.
  5. Confirm the rolling update
  6. Wait for the rolling update to finish

Screenshots for selecting “APs” with narrow and wide tab widths:

Unifi Cloud Key: “We have detected that your SD card is missing. Please insert it and reboot your Cloud Key or disable automatic backup.”

Posted by jpluimers on 2021/04/23

Got this a while ago with 5.10.17:

“Missing SD card”

“We have detected that your SD card is missing. Please insert it and reboot your Cloud Key or disable automatic backup.”

This might be a hardware issue with [] Ubiquiti UniFi Cloud Key, UC-CK: AmazonSmile: Computer & Zubehör

Reading the 1-star reviews, SD-card problems seem paramount: [] Ubiquiti UniFi Cloud Key, UC-CK.

For me, most of the times this solved the problem:

  1. Power down the Cloud Key
  2. Remove the SD card
  3. Insert the SD card
  4. Power up the Cloud Key
