Cache the update on the controller first, reboot your UniFi controller application, and then power cycle the U6-LR switch port to force re-adoption. 5. Firmware Best Practices for Production Environments
Wait 3 to 5 minutes for the device to download, flash, and reboot. Method B: Manual Upgrade via Web URL
Upgrading your U6-LR can be achieved natively through the UniFi dashboard or via manual terminal commands. Method 1: Automatic / One-Click Update (Recommended) Open your dashboard. Navigate to the Devices tab from the left sidebar. Locate your U6-LR in the device list. u6lr latest firmware
The primary symptom was APs ignoring manually configured channel plans and constantly drifting channels, which is particularly destructive for wireless mesh networks that require APs to remain on the same channel to maintain uplink connections. This constant channel changing led to isolated APs dropping from the network, frequent client disconnections, and overall network degradation. Ubiquiti community logs confirmed this behavior, showing a flood of "AP Channel Change" events after the update.
Confirm your switchport delivers true 802.3at PoE+ power (minimum 25W per port). If using a PoE injector, ensure it is rated for gigabit speeds and outputs at least 48V, 0.5A. Best Practices for Enterprise Deployments Cache the update on the controller first, reboot
The U6-LR is a power-hungry access point requiring a strict PoE+ (802.3at) power source. Standard PoE (802.3af) switches or injectors may cause the AP to crash and reboot infinitely when bootstrapping the radios under new firmware modules.
