" Note:
1.LAN IP of extended router should be different but in the same subnet of the root router;
2.The DHCP Server on extended router should be disabled;
3.WDS bridging only requires the WDS setting on either the root router or the extended router.
4.Make certain whether your router supports WDS or not."
That’s what I thought, that I should not be the same IP as the main router, I tried it once, but then the mini router didn’t connect.
Gonna try it again
