ASUS RT3100 not connecting to Cable Modem C3700

There was a Xfinity outage due to weather and when service came back I had to reset both the cable modem and router. I had to call Xfinity to reset / test the modem and now have WiFi working - but the ASUS router has a no Internet connection even after several restarts/resets.

 

The netgear WAN is set to Router Access and I cannot figure out why the ASUS router does not have connectivity. Is there some other Netgear settings that I have have overlooked?

 

Would appreciate some suggestions. 

Thanks

       That address should work if the C3700 is configured as a
    modem+router.  As a (DOCSIS) modem-only, you might try "192.168.100.1".

    Either bridge the C series modem or keep the C series modem in router and and set the asus router for AP mode.

      Thanks FURRYe38 I was able to connect to the C3700 (router Mode) and ASUS (AP mode) but my original plan was to take adv of the ASUS as the router.. what I did

       

      - Disabled the C3700 router mode

      - Enabled the ASUS as router

       

      but the ASUS does not connect to the model - solid red light after reboot.. I have attached my settings doc; I must be missing something in the modem settings..

       

      Thanks

        The Router Mode feature on the C modem needs to be set to NO. This will bridge the C modem setting it for Modem only, then configure your ASUS router for router mode, not AP mode.
