+# Comcast Bridge Mode
+
+You are ready to make the Netgear RS router your sole router, and switch the Comcast router
+to being a "dumb modem". This will disrupt network connectivity for all devices in your home.
+
+Hopefully, just for a few minutes.
+
+## Switch Comcast router to bridge mode
+
+- Connect the Netgear RS router to one of the LAN (local network) ports on the Comcast router.
+- Disconnect any other wired connections from the Comcast router - such as your node -
+and connect them to one of the LAN (local network) ports on the Netgear RS router. The 2.5G
+ones are nice if your node has 2.5G support, and don't hurt if it doesn't.
+- Connect to the Comcast router via LAN or WiFi, navigate to `http://10.0.0.1`, and switch
+"Bridge Mode" to "Enabled". Comcast has [instructions](https://www.xfinity.com/support/articles/wireless-gateway-enable-disable-bridge-mode)
+for this.
+
+In our testing, the Netgear RS router did not receive an external public IP right away.
+We power cycled the Comcast router/modem and the Netgear RS, and then it worked.
+
+You can see the external address at Advanced -> Internet Port -> IP Address. Netgear have
+[documentation](https://www.netgear.com/hub/technology/what-is-router-ip-address/) for this.
+
+A public IP is any that isn't private: Does not look like `192.168.x.x` or `10.x.x.x` or `172.16.x.x` through
+`172.31.x.x`.
+
+## Configure IPv6 on Netgear
+
+Comcast offers IPv6 services in the US, and we'd want that to continue working for you.
+
+On the Netgear web interface, go to Advanced -> Advanced Setup -> IPv6, and set "Internet Connection Type" to "Auto Detect", then click "Apply"
+
+You can verify this worked by coming back to that page and seeing that an IPv6 address has been assigned to the Netgear RS. Your devices on
+the network should also show that they have both an IPv4 and an IPv6 address.

+We've tested and documented switching to a Netgear RS300 on Comcast. Any router in the
+[Netgear RS line](https://www.netgear.com/home/wifi/routers/listing-filter/ax-wifi7/) should work the same way.
+
+The Netgear routers have a mobile app as well as a web interface. We've documented setting it up via
+the web interface from a laptop.
+
+- [App instructions](https://kb.netgear.com/119/How-do-I-set-up-and-install-my-NETGEAR-router)
+- [Laptop instructions](https://kb.netgear.com/22697/How-do-I-install-my-NETGEAR-router-using-the-router-web-interface)
+
+Where it says "connect your modem to the yellow Internet port on the back of your NETGEAR router", the
+"modem" here is your current ISP router. Use one of its Ethernet LAN, local network, ports, to connect to the "Internet"
+port on the Netgear RS.
+
+Netgear will prompt you for an admin password, download a firmware update, and restart. At that
+point, you should be able to log in with the new admin password and continue setup.
+
+Netgear defaults to an internal `192.168.1.0/24` network. We haven't tested what happens if that also happens to be
+the default network of the ISP router. It's possible firmware update will fail, or that you'll need to set up the Netgear router
+without Internet connection, and connect it only after the ISP router has been switched to "bridge mode". Firmware
+update in that case would happen as the last step, not the first step.
