The latest official firmware for the Ubiquiti UniFi U6-LR , released on February 4, 2026. Recent Firmware Versions Release Date Key Highlights Feb 4, 2026
The U6-LR has a powerful radio. On the 5GHz band, if you use DFS channels (channels 50-144), the AP is sensitive to radar detection. Recent firmware updates improved the "listen before talk" logic, but if you live near an airport or weather station, DFS events will still force the AP to kick clients and re-scan. It is often recommended to use Non-DFS channels (36-48, 149-161) for the most stable performance on this specific model. u6lr latest firmware
