So I got my AX86U Pro setup today, everything's working, except 2 older computers, are no longer compatible. I tried connecting the N66U via ethernet cable to one of the ports on the AX86U, and voila, the computers were connected to the N66U with internet. Now I'm thinking, is there any way for me to connect the N66U via wireless to the AX86U, and still use the N66U as a wireless access point ?
