XR450 Nighthawk wifi router need help connecting to Comcast modem. Modem connects well directly to decktop computer but not when ethernet goes first to previously setup router

Have you got your router set to use DHCP in Internet Setup?
&nbsp;
It might be a good idea to connect your modem to your router, and then do a factory reset. This will run through the setup procedure again and hopefully detect your internet connection correctly.

What Firmware is currently loaded?What is the Mfr and model# of the ISP modem the NG router is connected too?&nbsp;Be sure to power OFF both ISP modem and XR router for 30 seconds. Then power ON the ISP modem first and let it sync. Then power ON the XR router. It should connect or walk thru the setup wizard after doing a factory reset and setup from scratch.&nbsp;MLask&nbsp;wrote:XR450 Nighthawk wifi router need help connecting to Comcast modem.
