FIRMWARE 3.9.3.7537 for UAP/USW has been released

We’ve prepared firmware 3.9.3.7537. Please see below for the changelog and links to the firmware binaries.

Firmware changes from 3.9.2:

• [ACIWPro] Enable DFS support.
• [UAP] Add more security details to scan info.
• [UAP] Security patch for the WPA2 vulnerability called KRACK (details Lord).*
• [UAP] Various backend fixes and/or improvements.
• [USXG] Fix fastpath tools.

*This primarily affects devices that support STA mode. It’s worth noting that 1st gen AC devices do not support STA mode, which is why we have only released a 3.9.x firmware.

Links are all HTTPS. This assumes your device(s) are currently running at least 3.7.51, and that the device’s date is properly set (ie it can reach a NTP server). If you encounter issues with the upgrade, or your device isn’t on a minimum supported firmware, then you can change the link to HTTP before performing the upgrade.
