I tried to set up the TP-Link Archer VR1600v as an access point (secondary). I reset the router, changed the IP address, disabled the DHCP, disabled VLAN, checked the subnet was the same as primary router.. LAN connection from primary to LAN port connection on secondary router. I could not get it to work! Is there a trick here that anyone can help? Or this router cannot be used as an AP?? Thank you.
