On units with the 2.4" monochrome LCD, the contrast setting resets to default after every power cycle. Workaround: Add set lcd_contrast 45 to the /etc/rc.local startup script.
HP’s Vectra XW line of workstations uses entirely different BIOS and firmware systems.

During its peak, many users considered the 5.6.x branch more stable than the early 6.0.x releases, which faced initial performance issues. Ubiquiti Community Known Challenges & Limitations XM vs XW Firmware - Ubiquiti Community
It is highly recommended to update your device to to ensure optimal performance. The installation process generally follows these steps:
Firmware versions under the airOS v5 umbrella lack modern cryptographic protocols. Most notably, v5.6.11 does not feature signed firmware validation, an essential defense introduced globally in later service releases (such as v5.6.15 and airOS v6) to prevent malicious scripts or forced network infection. Running v5.6.11 exposes devices to known web UI and SSH configuration bugs if exposed to public IP addresses. 2. Regulatory and Frequency Variances On units with the 2
These steps carry significant risk of bricking your device and should only be undertaken with a clear understanding of the consequences.
