UniFi WiFi
SSID and access point settings that matter in a homelab: bands, 6 GHz, IoT networks, multicast and roaming. Settings move between releases, so confirm names in your version.
Documentation: SSID and AP Settings Overview · Getting Started with 6 GHz · Unable to Connect to WiFi
SSIDs #
- One SSID on several bands is preferred over a 6 GHz-only SSID.
- Tie each SSID to a network, see UniFi Networks and VLANs.
- Use a separate SSID for IoT and another for guests.
Bands and Security #
| SETTING | NOTES |
|---|---|
| 6 GHz | Needs WPA3 or OWE. Turning it on defaults to WPA2/3 with PMF optional |
| PMF | Optional (default), Required (WPA3 and OWE), or Disabled. It cannot be disabled on WPA2/3 or WPA3 |
| Band steering | Now uses BSS transition frames. The old AP-level method is deprecated |
| Multicast Enhancement | Converts multicast to unicast |
| DTIM | Defaults 1 on 2.4 GHz and 3 on 5 and 6 GHz |
| MLO | Multi-link operation, a WiFi 7 option |
IoT SSID #
Ubiquiti’s advice for devices that will not connect:
- Create a separate SSID with 6 GHz off and WPA2.
- WPA3 is not recommended on 2.4 GHz.
- Disabling PMF is suggested only for troubleshooting.
- Keep the SSID on an IoT network with a firewall zone, see UniFi Firewall and VPN.
Roaming #
Fast roaming (802.11r) and minimum RSSI are described only by third-party guides and were not verified officially. Change one setting at a time and test with the devices you care about, because some IoT clients dislike 802.11r.
Not Covered or Unverified #
Radio AI, WiFi Experience, Zero-Wait DFS, hotspot portals, PPSK, WiFi scheduler, mesh uplinks and channel width guidance were not researched.
