Why is Xfinity Ethernet not Working?

Xfinity Ethernet Cable

Check the cable to check whether it has been broken or damaged. The most straightforward option is to replace the cable with another and see whether the second cable performs as expected. If you don’t have access to another cable, or if the wire is buried in the wall, you’ll be out of luck. There are routers and Ethernet switches that, even though it is a more specialised solution, can check for broken connections and alert you of the time it took to identify the issue.

My previous experience with some of these devices includes testing Zyxel switches, especially the Zyxel XS1930-12HP and the EnGenius ECS1008P, as well as other brands and other brands similar devices.

Xfinity Ethernet Network

If the message “Unidentified network” appears on the screen, turn the Ethernet network off and on again. It is simple to resolve this issue by going to Control Panel > Network Connections, right-clicking on the Ethernet network, selecting Disable, and selecting Enable in Windows. Hopefully, you should now be able to connect to the Internet through a wired connection at this point.

Xfinity Ethernet Router

It’s possible that your router is to blame. When the Netgear AX40 (v1) was experiencing connectivity issues with wired clients, a reset was required before the network could be utilised again. Depending on whether or not you can access the Internet (through a wired connection) after restarting your router, you may not need to purchase a new one in the future.

A faulty Internet connection is the most prevalent factor when things don’t operate as expected. You’re good to go if you know the username and password for your ISP’s router (or app). With a Quick Internet Setup, you may re-enter your account information to have an Internet connection back up and running (or a similar variant). Again, Parental controls may have been enabled on this device.

Parents who use Parental Controls often overlook that they have scheduled Internet access for one or more devices in a Profile they’ve set up. Cancel or disable scheduled Internet access using the router app or web-based UI.

How to Fix Xfinity Ethernet Not Working

If you are having problems with your Ethernet connection, the first step is to ensure that the problem is with your Ethernet and not with your whole network. There was much discussion regarding people experiencing Wi-Fi disconnections at odd hours of the day or night. This may be accomplished by unplugging your computer from the Ethernet network and connecting only to the Wi-Fi.

Otherwise, the problem is most likely with your Ethernet connection, which you may focus on resolving later. If you cannot connect to the internet by Wi-Fi or Ethernet, it is most likely that your Internet Service Provider (ISP) is a fault. The network may be experiencing difficulties, and you should contact your Internet service provider to find out when the issue will be resolved if one exists.

Having your internet connection fail may be pretty frustrating, but there are a few ways you can try to fix the problem.

Reboot the Router

 Like any other electrical device, your Xfinity router has software that instructs the router’s hardware to execute specific tasks. Problems with your network may arise as a result of this firmware. Rebooting your router usually takes care of most problems. To remove undesired codes from a device’s memory, it may be necessary to reboot it. Many technological problems may be solved quickly and easily by rebooting the computer.

The Xfinity router may be restarted in one of two ways. The power supply must be unplugged and then plugged back in to continue using the router. Using the Xfinity app on a smartphone, restarting your router is also feasible.

The rebooting process is :

  • Log in to your Xfinity account and go to the Internet menu to get started.
  • Choose ” Restart this device ” from the drop-down menu in the router’s status bar, and choose “Restart this device.”
  • Click “Restart Device”, being sure enough.
  • It will take anything from 5 to 10 minutes to completely restart your smartphone.

Restart the Router

After trying to reboot the router, you may choose to reset it to factory settings if the issue persists. Unlike a reboot, a reset router completely wipes the hard drive of any data that may have been saved. Any previously saved Wi-Fi names or passwords are wiped clean to return your router to its factory default settings. Find the reset button on the back of your Xfinity router and press it to do a factory reset.

A typical configuration is a small, recessed button separate from the rest of the router’s body. The front lights of the modem should turn off entirely after being gently pressed and held in place with a paper clip or a pen. The router will reboot in seconds, and the lights will turn on. When you reset your router, all of the data is wiped off is essential to keep in mind. To reactivate and re-configure the router, use the same steps you used to install and configure it the first time.

Replace the Ethernet Cable

Double-check that your Ethernet cable is securely connected to the router’s LAN port. Another common cause of problems is your Ethernet wire. If your cable is kinked, bent, or penetrated by nails or staples, it must be replaced immediately. If twisting or holding the wire at a certain angle solves your issue, the LAN port on your router may be defective. A Comcast Service Center can repair your router if this is the case.

Replace the Ethernet Port

A faulty Ethernet port on a device can almost always be repaired or replaced. However, according to many recommendations, it should be replaced if you suffer from similar symptoms at the earliest opportunity.


If you’re using the Xfinity Voice modem, you’ll need to reset it with a non-metallic pointed item, so keep that in mind while troubleshooting. Your ethernet connection should be operational at this point.
