This article describes how to select the correct firmware, either for the XW or XM platforms of an airMAX M device; or the XC or WA platforms of an airMAX AC device.
NOTES & REQUIREMENTS:
The "correct firmware" will always be the latest release. The airMAX team is hard at work adding improvements to each new version. For security reasons, please be prompt to update all your devices to the latest firmware available in the Downloads page.

In 2015, the new airMAX AC line of products was released. This platform requires different firmware than the XM/XW used with the airMAX M line. The airMAX AC products use either XC or WA. You can easily check to see which firmware is needed for your specific model by checking the Main Dashboard of the airOS webUI.
Identifying a Device's Platform
The airMAX M devices use XW or XM platforms. Identify which one by looking at the firmware version in the device's SYSTEM tab; or by checking the firmware version in the MAIN tab.
XW devices will display an 'XW' before the firmware version. In the example above, the firmware is 6.1.6 and for XW devices. XM devices will show an 'XM' before the firmware version.
Older M devices are XM while most new M devices are XW. The first Rocket Titaniums were TI, but new Titanium Rockets are also XW. These changes were rolled in over an extended period of time.
If you cannot log into a device to check the board version, it is safe to attempt the wrong firmware first. You will only see an error.
Identify if your airMAX AC product uses XC or WA platform by looking at the firmware version in your device's maintab. The device's platform, as well as the firmware version will appear in the top bar of the UI as well as in the version line.
XC devices will display an "XC" next to the firmware version. In the example above, the firmware is 8.0.2 and uses the XC platform. On the other hand, WA devices will show a "WA" next to the firmware version.
For those rare cases where logging into the device is not possible, use this table to see which firmware is required for each AC device.

3. Click on the correct firmware, selecting the correct board: airMAX M's XM or XW, and airMAX AC's XC or WA. In some cases, the board firmware version number could be different. In all cases, it's recommended to have the latest firmware version available for your device's platform.
