Hi TripleNetwork,
Wifi mode in ePMP is supported only on the subscriber module (SM). When the SM is in Wifi mode, it can connect to an Access Point (even a non-Cambium Access Point) that is operating in Standard Wifi mode. It is a feature you can use to migrate from existing deployments to ePMP.
You cannot use Wifi mode on ePMP to connect Wifi clients to it. i.e it does not operate as a Wifi Access point. That is something a few customers have requested in our Ideas section: http://community.cambiumnetworks.com/t5/Your-Ideas/Mesh-WiFi-AP/idi-p/37373. Take a moment to kudo the idea if you'd like to see it developed by Cambium. We're always listening to customers and changing our roadmap based on demand.
Please let me know if you need further clarification.
Thanks,
Sriram
