Note:

If your firmware version is 2.2.1.210 or lower, you cannot update the firmware directly to v2.3 or higher. You must first update the firmware to v2.2.1.212 using the manual firmware update feature in the router web interface.  After updating the firmware to v2.2.1.212, your Orbi router reboots, and then you can update to higher versions.

Security Fixes:

• Updates the https certificate.
