Ubiquiti USG-XG-8 Access Point Firmware 4.4.18.5052174

- Removed core handling script that was causing reboots when large core files were generated
- Fix IGMP proxy failing to start during boot a few were experiencing.
- Fix potential issue of UPnP failing to start during boot.
- Change IPS loading of ipset contents to more efficient method to greatly reduce CPU usage after initial bootup and enabling of service.
- Other IDS/IPS back end improvements
- Fix ubnt-cfgd zombie process issue
- Added SNMPv3 back end
- Added lock wait to all iptables operations to avoid errors in cases where multiple operations happen simultaneously.

- VLAN hardware offload problem fixed

Upgrade WARNING:

- If you have GeoIP enabled, disable it first, then upgrade USG, then enable it again.
- The configuration has changed in a way that limited unstable controller and firmware version combinations could result in an invalid configuration on the new firmware versions.
- In that circumstance, if the upgrade is performed with GeoIP enabled, the system will have to be reset to factory defaults post-upgrade.

Downgrade WARNING:

- If you upgrade to any version supporting DPI without offload, disable offload (or enable IDS/IPS) and enable DPI, you cannot downgrade to a version that does not support DPI without offload.
- Either disable DPI, or enable hardware offload (or disable IDS/IPS), before downgrading. Otherwise you'll have to reset to factory defaults post-downgrade and adopt again.

About Switch Firmware:

Given the large variety of models and different methods for upgrading the switch, if you wish to apply this package, we recommend that you read and understand the installation steps before you install a new firmware, even if you are a power user.

Usually the update procedure isn't much of a hassle as manufacturers try to make it as simple as possible; however, there are cases that are exceptions to this rule. First off, go to the system information page of the switch to check that the currently installed version isn't either newer or matching this release.

Applying a new firmware can decrease the security vulnerabilities, enhance overall performance and compatibility, improve various power management functions, resolve different errors, and add support for newly developed technologies and protocols.

It is recommended that you perform this step in a steady power environment such as the one ensured by a UPS unit, and that you don't interrupt the upgrade in any way, because this might cause the switch to malfunction.

That being said, click the download button, get and apply the new version, and check back with our website constantly to stay up to speed with the latest releases.
