I have the AC68U and previously a friend helped set it up to use his VPN. When his VPN became unavailable I stopped using the modem. Today my internet provide gave me a new cable modem, D-Link DCM-3012G, but it doesn't have wifi. So I figured I would just connect the AC68U, connect the WAN port to the cable modem and be on my way. The problem is that the AC68U was all configured for the VPN. Now I just want to use it as a vanilla wifi router rather than with a VPN setup. I upgraded the modem from v132-VPN to v140-AIO and cleared the NVRAM. Other than configure the SSIDs and security, I can't seem to figure out how to have it just grab an IP from the cable modem and enable me to use Wifi to get out to the Internet. I went through the FAQ thread and can't seem to see anything for plain initial setup. Any pointers very much welcome.
