It is possible to use an Apple AirPort Extreme to extend a Comcast router, but it requires a wired Ethernet connection. This can be done by connecting the AirPort Extreme to the Comcast router using an Ethernet cable, and then configuring the AirPort Extreme to create a wireless network with the same name, security, and password as the Comcast network. This will effectively extend the network. However, it is important to note that Apple uses proprietary settings for its extend a wireless network feature, which are designed to only work with other Apple routers. Additionally, some users have reported issues with extending a Comcast network, such as connection drops and password issues.

Using an Ethernet cable to connect the Airport Extreme to a Comcast router
To connect an Airport Extreme to a Comcast router using an Ethernet cable, you must first ensure that the Airport Extreme is located at least a few rooms away from the Comcast router to avoid interference effects and confusion for wireless devices.
Next, you will need to connect the Ethernet cable to one of the four LAN ports on the back of the Comcast router and run it to the location of the Airport Extreme. Once the cable is connected, turn off the WiFi on your computer and connect your computer directly to the Ethernet cable. Check if your computer can access the internet through this connection. If it can, then the Ethernet cable is working correctly.
After confirming the Ethernet cable is functioning properly, you can proceed to set up the Airport Extreme. Power on the modem and wait at least 5 minutes. Then, power on the Airport Extreme and wait another 5 minutes. Finally, power on your computer(s) and check if the modem recognizes the internet router. If not, you may need to perform a full modem/router power recycle by powering off all devices, waiting at least 30 minutes, and then powering them on again in the following order: Comcast router, Airport Extreme, and computer(s).
Additionally, since you are using two routers in series, the Airport Extreme must be configured in Bridge Mode to function correctly on the network. You can do this by opening AirPort Utility and selecting Bridge Mode. After making any changes, power down the entire network and restart the devices one at a time, starting with the Comcast router, followed by the Airport Extreme, and then your computer(s).
Once the Airport Extreme is set up, you can configure it to create a wireless network with the same network name, security, and password as your Comcast network. This will allow your devices to stay connected to the same network as they move between the Comcast router and Airport Extreme coverage areas.

Ensuring the Airport Extreme is located away from the Comcast router
When setting up an Apple AirPort Extreme to extend an Xfinity or Comcast network, it is important to ensure that the AirPort Extreme is located away from the Xfinity or Comcast router. This is because, if the two devices are in close proximity, they will both be broadcasting the same wireless signal, which can cause confusion for wireless devices and lead to unwanted interference effects.
To avoid these issues, it is recommended to place the AirPort Extreme at least a few rooms away from the Xfinity or Comcast router. For example, some users choose to locate the AirPort Extreme in the basement or at the back of the house, while keeping the Xfinity or Comcast router in the front of the house. This ensures that the AirPort Extreme is extending the wireless network to an area that the Xfinity or Comcast router cannot reach on its own.
In addition to the physical distance between the AirPort Extreme and the Xfinity or Comcast router, it is also important to consider the type of connection between the two devices. A permanent wired Ethernet cable connection is recommended to connect the AirPort Extreme back to the main router. Ethernet cabling can be run up to about 330 feet or 100 meters with virtually no loss in signal strength, providing a good foundation for the AirPort Extreme to work with.
By ensuring that the AirPort Extreme is located away from the Xfinity or Comcast router and connected via Ethernet cable, you can effectively extend your wireless network to cover a larger area while minimising potential interference and connection issues. This setup allows you to bring wireless connectivity to dead zones in your house and improve the overall performance of your network.

Troubleshooting when the Airport Extreme doesn't connect to the Comcast router
Firstly, it is important to note that the Airport Extreme can be used to extend a Comcast router. However, there are some considerations and limitations to this setup. One issue that may arise is interference between the two wireless routers, which can degrade performance. To avoid this, it is recommended to place the Airport Extreme at a distance from the Comcast router.
If you are experiencing connection issues, there are several troubleshooting steps you can try. Begin by checking the Ethernet connection between the modem and Airport Extreme. Connect your computer directly to the modem using an Ethernet cable to verify if the Internet connection is working. If your computer cannot connect to the Internet, then the Airport Extreme will not be able to either.
Another step is to reset the Comcast modem while the Airport Extreme Base Station (AEBS) is powered down. Once the modem finishes its test cycle, plug the AEBS back in. You can also try resetting the AEBS by powering it off, along with any connected Airport Express devices. Move the Airport Express devices closer to the AEBS, power up the Airport Express, and then hold the reset button for 7-8 seconds before releasing.
If the issue persists, there may be a compatibility problem between the modem and Airport Extreme. In such cases, the Airport Extreme may need to be configured in "Bridge Mode" to work correctly with certain modems. Additionally, when changing the modem or Internet provider, it is recommended to reset the Airport Extreme to factory default settings and then set it up again.
If you are using a Mac, ensure that you have the latest operating system installed. The specific steps to set up the Airport Extreme as a new base station may vary depending on your Mac's OS version.

Opting out of broadcasting a public hotspot off a Comcast router
Comcast has been known to use its customers' modems to provide Xfinity hotspot Wi-Fi services to other Xfinity customers. This is done without explicit permission from the customers, who are automatically opted into the service via the terms of service. However, there is a way to opt out of this programme.
Disabling or opting out of the Comcast Xfinity public Wi-Fi hotspot network is a fairly simple process. However, there have been reports of customers running into issues, and you may have to periodically re-opt-out. To opt out, go to the Xfinity website to manage your preferences and turn off the hotspot feature. If you encounter any issues, you can call Comcast customer service at 1-800-934-6489 (1-800-XFINITY).
If you are still having issues with your Comcast router broadcasting a public hotspot, you may want to consider purchasing your own modem and not using the one provided by Comcast. Alternatively, you can take apart the Comcast modem and physically cut the PCB trace going to the antenna.
