Review: UniFi UXG-Lite

Several years ago, I replaced the networking gear at my parents’ place with a UniFi Security Gateway, access points, etc. The setup has been working reasonably well and the only major issue was when the USG died and I had to replace it (turns out it was probably just the power supply, but I learned that too late). While the USG performed adequately (they only have a 100 Mbps down/10 Mbps up Internet connection), finding a replacement USG in case it failed was getting harder and harder (I had a spare on my shelf just waiting for it to die). Ubiquiti really didn’t have a decent replacement for the USG until recently when the UXG-Lite came out.

Prior to me seeing that the UXG-Lite had been released, a friend of mine sent me a UniFi Cloud Key Gen 2 Plus which I setup to replace the outdated UniFi NVR (no longer supported and no remote access was available) and CloudKey Gen 1. This allowed my dad to use UniFi Protect and view his cameras remotely.

Once I saw the UXG-Lite released, I immediately purchased one as it looked (for the most part) like a direct replacement for the USG. One of the requirements to running it was a newer UniFi controller which I had just installed so I was good to go. One of the immediate differences in the UXG-Lite was that it only had 1 WAN port and 1 LAN port while the USG had 1 WAN port, 1 LAN port and then 1 WAN/LAN port. I had originally setup my parents network with 2 separate LANs, but realized that all the traffic on 1 LAN was wireless so I could simply set a SSID to use a specific VLAN and still be able to isolate traffic.

Installing the UXG-Lite was a breeze. First I updated the controller to the latest version, then I forgot the USG in the controller and then adopted the UXG-Lite. All the settings were transferred and the whole process only took a few minutes. Since the USG was not powerful enough to handle IDS/IPS, I had that turned off. Once the UXG-Lite was setup, I turned that on just for some added piece of mind.

I also setup a WireGuard VPN into the box (not possible with the USG) and that seemed to work just as flawlessly as it does on my UDM-SE. I can’t imagine using it much, but it is there if I ever need it. The remote management of the network does all that I need to do without connecting directly to the network.

The UXG-Lite has been running for a week and I haven’t heard any complaints, so I’m going to call it a success. I was just looking for a modern replacement for the USG and that seems to be what it is. I’ve seen various reviews/complaints about the device, but in my limited testing I’m not seeing any issues.


  • Easy setup
  • Integrates with the rest of the UniFi line of equipment


  • Lacks second WAN/LAN port


If you’re looking for a replacement for the USG3, the UXG-Lite seems to foot the bill. While the UX (UniFi Express) has also been released, it wouldn’t meet my needs in the case due to using UniFi Protect to run cameras. If I hadn’t needed that, the UX may have worked. Remember that the UXG-Lite still needs the controller running on another piece of hardware so if you need an all-in-one box, this isn’t it.

I no longer have to worry about trying to replace an outdated equipment when the USG eventually broke. I’m still a huge fan of UniFi equipment and while it may not be commercial grade, it works for my home needs and being able to manage my parents’ network remotely is a lifesaver.
