Thanks for your reply. I tried to setup with both bridged mode and tunnel mode. Both of them, I wasn't able to get the IP on wifi client. Wired connection worked fine but not the wifi client. It connects but no IP. I must have missed something. Basically, I created a SSID with bridge mode and no IP assigned, created a SW switch with a physical port and a SSID as a member, assigned IP and setup a DHCP pool.
