I could not find WDS option on the setup page. How can I setup WDS to connect the AX53 to the main router wirelessly?

Hello @Zapiquin,

As per the User Manual for Archer AX53, it doesn't support WDS:

https://static.tp-link.com/upload/manual/2021/202111/20211111/1910013106_Archer%20AX53_UG_REV1.0.0.pdf

It only supports Router Mode and Access Point Mode. You will need to connect it to the main router with an Ethernet cable by configuring it into an AP mode. 

Or, you can confirm if you can configure the AX53 as the main router, and connect the existing main router to AX53 via WDS if that one supports it.
