UniFi repeater: how to set up an AP as a WiFi extender

UniFi doesn't have a "repeater mode" setting. To use a UniFi access point as a repeater, you use wireless meshing. The AP connects to another UniFi AP over WiFi and broadcasts the same networks, so you don't need to run a cable to it.

You need three things:

  • A controller running UniFi Network.
  • Wireless meshing turned on.
  • At least one AP with a network cable, within good range of the new one.

Ubiquiti's own advice is to wire APs when you can. Meshing is the alternative for spaces without Ethernet (Considerations for Optimal Wireless Mesh Networks).

What you need for a UniFi repeater

  • A controller. That can be a UniFi Cloud Gateway, a Cloud Key, UniFi OS Server or a hosted controller. Ubiquiti says meshing isn't available for APs in standalone mode, so an AP set up only in the mobile app can't be a repeater. Our guide to running a UniFi AP without a controller explains standalone mode.
  • One wired AP. Ubiquiti's adoption steps for meshed APs apply to "UniFi APs connecting wirelessly to a wired uplink AP".
  • APs that support meshing. On September 25, 2026, every UAP, U6, U7 and E7 access point listed on Ubiquiti's tech specs site showed Wireless Meshing as a feature. That runs from the UAP-AC-Lite to the U7 range.
  • Power at the new spot. The repeater still needs power. Only the network cable goes away.

WiFi 7 APs can mesh with older ones. Firmware 8.0.49 for the U7 and E7 models (June 2025) enabled meshing from those APs, with MLO turned on, to WiFi 6 and WiFi 5 APs.

How to set up a UniFi AP as a repeater

These steps come from Ubiquiti's articles on device adoption (edited July 2025) and wireless meshing (edited April 2025). Menu names can shift between UniFi Network versions.

  1. Adopt and set up the wired AP as usual.
  2. In UniFi Network, go to Settings > WiFi > Wireless Meshing and turn it on. Since Network 7.5.176 (September 2023), a wireless adoption turns it on automatically.
  3. If the second AP was used somewhere else, factory reset it first. Hold the reset button for 5 to 10 seconds while it's powered.
  4. Power the second AP near the wired AP, with no network cable. Ubiquiti says to place it close to the uplink AP for a stable signal.
  5. Adopt it in UniFi Network when it appears.
  6. Check the mesh settings under UniFi Devices > [select the AP] > Settings. Ubiquiti's mesh article says to turn on Mesh Parent on the wired AP and Mesh Connect on the AP that connects over WiFi.
  7. Move the AP to its final spot and check the signal to its parent.

Ubiquiti's two articles disagree here. The newer adoption article (July 2025) says to turn on Mesh Connect on the uplink AP. The mesh article (April 2025) says Mesh Connect is for the AP that connects over WiFi. We follow the mesh article, because Network 10.1.84 (February 2026) agrees with it. It added a notice that suggests turning off Mesh Connect on APs with a wired uplink. The mesh article also warns that Mesh Connect on a cabled AP can cause routing problems or loops.

An AP that has lost its network connection and is looking for a wireless uplink shows a blue LED that flashes off every 5 seconds.

How fast is a UniFi repeater?

Expect roughly half the speed per hop. Ubiquiti puts the loss at about 50% for each wireless hop, compared with a wired AP (Maximizing Wireless Speeds, edited July 2026). A second Ubiquiti article says "at least 50%".

Ubiquiti's other performance advice:

  • Keep it to two wireless hops at most. Place a repeater near a wired AP, or near an AP with fewer hops.
  • Don't connect too many repeaters to one parent AP. Spread them out.
  • Aim for a signal of -60 dBm or better between the repeater and its parent.
  • Mesh links mainly use 5 GHz. A crowded 5 GHz band slows them down. DFS channels are often less busy. Our guide to setting WiFi channels manually covers how.

Meshing also lowers the number of WiFi networks an AP can broadcast. Ubiquiti's SSID article (June 2024) says an AP can broadcast four SSIDs per band, or eight when Wireless Meshing is off.

How to stop a UniFi AP from acting as a repeater

  • Connect the AP with a network cable, then turn off Mesh Connect on it.
  • If no APs connect wirelessly anymore, turn off Wireless Meshing. Ubiquiti recommends this to prevent network loops (Understand and Mitigate Network Loops, edited September 2026).

The Network 9.0.108 release notes (December 2024) say wireless meshing is turned off automatically when a device is adopted over a cable. Since Network 7.3.83 (January 2023), UniFi Network blocks turning off Wireless Meshing while devices still connect through it.

Troubleshooting a UniFi repeater

  • It won't adopt. Check that Wireless Meshing is on. Move the AP closer to the wired AP. Ubiquiti suggests a factory reset as the last resort.
  • It's slow. Check the signal to its parent (-60 dBm or better), the number of hops, and how many repeaters share that parent.
  • Devices stick to the wrong AP. Our guide to UniFi fast roaming covers the roaming settings.

Keep AP firmware current. In July 2024, for example, Ubiquiti disclosed a U6+ issue in firmware 6.6.65 and earlier. VLAN traffic could be forwarded incorrectly to APs meshed to it (CVE-2024-37380, fixed in 6.6.74).

Frequently asked questions

Does UniFi have a repeater mode?

No. There's no setting called repeater mode. Ubiquiti calls it wireless meshing: an AP without a cable connects to a wired AP over WiFi.

Do I need a controller for a UniFi repeater?

Yes. Meshing is set up in UniFi Network, and Ubiquiti says it isn't available in standalone mode.

Can I chain UniFi repeaters?

Yes, within limits. Ubiquiti recommends two wireless hops at most, because every hop reduces throughput.

Does a UniFi repeater cut the speed in half?

Yes, roughly. Ubiquiti puts the loss at about 50% per wireless hop compared with a wired AP.

Can I turn a meshed AP back into a wired AP?

Yes. Connect it with a cable and turn off Mesh Connect on that AP. If nothing meshes anymore, turn off Wireless Meshing too.

Final thoughts

A UniFi repeater is wireless meshing with one wired AP and a controller. It's a good fix for a garage, a garden office or an upstairs room without Ethernet. Keep it to one or two hops, check the signal, and expect about half the speed per hop.

For your own home, a Cloud Gateway or a self-hosted controller does the job. If you look after client networks, we run hosted UniFi OS Server for MSPs, with daily backups and monitoring on paid plans.
