I recently bought a new Netgear Nighthawk AC1750 that I wanted to use, since it lets me mess with many more settings than the Xfinity Modem/Router combo does. The xfinity documentation said to put the modem in "bridge mode" if using your own router, and I did so, connecting it to my new Nighthawk.
I was able to log into the router gateway and set up wifi names and passwords, but when I try to use it, I don't have internet connection. I'm not recieving any internet connection from my modem, wired or wireless. Also, I'm no longer able to access the modem gateway to change it off of bridge mode. I ended up reseting my modem to factory settings, and getting the internet connection working again. But, I'm still not able to use my new Router.
Any help with this? I don't know why the modem won't work in bridge mode when it should..
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
After putting the ISP modem into bridge mode, did you power OFF the modem and NG router for 1 minute then back on with the modem first then the router?
Be sure to restart your network in this sequence: Turn off and unplug modem. Turn off router and computers. Plug in and turn on modem. Wait 2 minutes for it to connect. Turn on the router and wait 2 minutes for it to connect. Turn on computers and rest of network.
What CAT# lan cable are you using between the modem and router? CAT6 is recommended.
Contact the ISP for additional help and information regarding there modem.
The startup sequence noted by @FURRYe38 above is important.
If your ISP gateway and new router are located in close physical proximity to each other (10 feet or less), consider turning off the Wi-Fi on the gateway. It will just cause interference with the Wi-Fi being transmitted from your new router.
Even in bridge mode, Xfinity limits how much of the Wi-Fi you can shut off. There are some hidden signals you have little control over. Such as the Xfinity Hotspot for instance.
