Follow Chapter 7 from your TL-WR902AC user guide to make it work as a wireless client to your wi-fi router.

Then from computer connected to your wi-fi router just access this wireless client (electronic board).

" Client: In this mode, this device can be connected to another device via Ethernet port and act as an adapter to grant your wired devices access to a wireless network, especially for a Smart TV, Media Player, or game console only with an Ethernet port. "

Are there any limitations on the electronic board? If no special settings, you can try to set up the WR902AC as a normal wireless router, it will provide you a wireless connection then:
