Connecting R7000 with Xfinity gateway in bridge mode - use WAN or LAN?
This seems to be a common problem but I still can't get the answer. I have an Xfinity XB3 wireless gateway (Cisco model #DPC3941T) and a Netgear R7000 Nighthawk wireless router. I've set the Xfinit...
Thanks TheEther. So I believe that Xfinity local IP network is using 10.0.0.1/255.255.255.0. I'm not sure where to change the subnet for the R7000. I do see a setting that says to get the Internet IP address dynamically from the ISP. Do I need to change it to use a static IP address?
No, leave the setting to get the Internet IP address dynamically from the ISP. You should confirm that the IP address listed on that page is a public IP address. In other words, it should NOT be 192.168.1.X, 10.X.X.X, or 172.16.X.X. If it IS one those addresses, then the Xfinity gateway is not in bridge mode. Otherwise, the R7000 should have received a public IP address.
The subnet that you want to change is under ADVANCED > Setup > LAN Setup. Since the Xfinity gateway is using 10.0.0.1/255.255.255.0, you can change the R7000's LAN IP address to 192.168.1.1 and subnet mask to 255.255.255.0.
