New Comcast customer

[Grega]

Hello,
From this morning I am Comcast customer (we moved to a new home). I have my Netgear CM1200 and wired connections works fine. I added my Asus AC86U and wirlesess is not working. I tried AP and Wireless router mode with no luck.
In Wireless router mode error message is "your isp dhcp is not functioning properly".
Please advise as I have no signal in my house right now and all devices are wireless
Thank you

My understanding is that the CM1200 is a cable modem only, not a router. Therefore you can only have one device plugged into it. So that would either be a single PC or a router (e.g. your AC86U). If you are using your RT-AC86U it must be in "router mode", it cannot be in AP mode.
