"Enable WAN" function on Reyee AP

Is there a list of devices that support the “Enable WAN” feature, which allows us to share the Internet connection on the WAN port after the AP has been messed up or used as a repeater?

Based on the screenshot and standard ReyeeOS behavior, there isn’t a specific restricted standalone "compatibility list" published by Ruijie. Instead, the "Enable WAN" feature is a universal system feature embedded into ReyeeOS for multi-port Ruijie Reyee RG-RAP series Access Points.  
When a Reyee AP drops into Wireless Repeater Mode (mesh or wireless uplink topology), the system automatically disables the physical WAN port by default to safeguard the network against broadcast loops, as explicitly called out in the notification text. Toggling this feature to "Enable" forces the physical WAN/uplink port back online, transforming the AP into a wireless bridge. This allows you to safely pass the wirelessly repeated Internet connection down out of that port and into a local switch or client device.

Verified Supporting Models Include:

• RG-RAP6262(G) (the exact model managed in the workspace)  
  
• RG-RAP6260(G) and RG-RAP6260(H) outdoor access points  
  
• Multi-port high-density indoor APs (like the RG-RAP2260 series)  
  
• Multi-port wall-plate series (such as the RG-RAP1200 series or the RG-RAP1261) when deployed in wireless repeater/mesh mode  
  
  

As long as the access point belongs to the Reyee RG-RAP family, features more than one physical Ethernet interface, and is running an updated version of ReyeeOS, this option will populate under the Advanced settings menu whenever the device operates via a wireless uplink.
