Can I connect a switch to the eithernet port of the TL-WR902AC to allow a few devices (like Raspberry Pi's) to connect via their ethernet ports when using the TP links Client Mode to connect to an AP that has internet access?   They are extremely low bandwidth.   Basically I am wanting to know if the ethernet port can see multiple MAC addresses when configured in Client Mode prior to purchasing one. 

I am trying not to have to run a physical ethernet cable thru the bowels of my RV and this device in client mode looks perfect to prevent crawling thru 40' of RV basement to run a wire from the back to the front of the coach for a couple of extremely low bandwidth devices.  

Thanks, Bill
