New Features and Enhancements:

Supports Access Control and MAC ACL in AP mode.

Bug Fixes:

Fixes certificate issue that blocked https login on Chrome.
Fixes incorrect client information when clients connect to Outdoor wireless 3.
Fixes an issue that prevented client access to the Internet. Note: We recommend you open MAC ACL and Access Control configuration and click Save to repair any incorrect settings.

Known Issues:

MAC ACL or Access Control can exceed configuration storage capacity with unexpected results in firmware version 2.4.0.114. Workaround: Upgrade to 2.5.1.106, and then go to the MAC ACL and Access Control settings and click Save to reapply the settings.
After updating router firmware, existing clients can be steered to the router because the wireless readiness in the router is faster than the wireless readiness in the satellite. Workaround: Connected clients might notice slower throughput or a weaker signal, which resolves when the user roams or reconnects.
Clients with hostnames that exceed 32 bytes do not display well in the Attached Devices page. To be fixed in an upcoming release.

Firmware Update Instructions:

The Orbi Outdoor (RBS50Y) uses different firmware versions depending on which wireless system you use. As of 2.3.5.22, RBS50Y detects whether the Orbi Router is an Orbi Pro system, and if so, automatically updates to Orbi Pro-compatible firmware.

If the firmware version is showing 0.0.0.0 on RBS50Y, the system is preparing to update to the Orbi Pro-compatible firmware

To update the Orbi Outdoor firmware from the local web interface, follow the instructions in your product’s user manual. To find your user manual, visit https://www.netgear.com/support/ enter your model number in the search box, and click Documentation on the product page. We highly recommend updating the satellite firmware first, and then updating the router firmware.

If the Orbi Pro is connected to the Insight cloud, perform a firmware update through the firmware schedule policy, or manually perform a firmware update using the Insight app or local web interface.

After updating to the latest firmware, make sure to update your version of the NETGEAR Insight app for the best functionality and user experience.
