Hi all. I have just purchased M9 2 pack to replace an ASUS RT-AC68U. To connect to the internet I have configured my ASUS as an access point and turned off both wifi radios connecting internet to the WAN. I have the M9 attached to the LAN in router mode and set up and working just fine, 3 wifi bars everywhere inside and out. 
 

My issue is I wanted to set the ASUS as the router (no wifi) and connect the M9 in either router or AP mode but I cannot get M9 to connect to the internet. What am I doing wrong? I thought I could set it up this way. I wanted this way so I could utilise the VPN on ASUS. At the time of trying to set it all up VPN was not turned on. 
 

Any advice appreciated.
