If your Xfinity ethernet not working, there are multiple solutions you can try to fix it.
As you are probably aware, a large number of users report this as a common issue, so we have prepared only the most successful and easy to apply methods at your disposal.
Xfinity ethernet might sometimes refuse to work due to hardware malfunction within the cable. You can otherwise try to restart your router and refresh your whole configuration. If that also doesn’t work, verify all of your cable connections before proceeding into the post.
In that regard, let’s first begin with what factors might impact your Ethernet functionality and learn how to fix each of them.
Why Is Xfinity Ethernet Not Working?
We figured it would be more appropriate to first mention all of the components from your Xfinity configuration that might have a malfunction so you can learn more about it.
There are three general aspects of your configuration that might be problematic. We will first begin with the Ethernet cable.
Xfinity Ethernet Cable
As you have probably guessed, similar malfunctions are generally due to cable malfunction.
Sometimes the cable itself gets worn out and there is nothing you could do but replace it.
To determine whether this issue is the cable’s fault, you must try a few different methods.
Happily, the preparations you have to do here will also include in the rest of the guide so don’t worry about wasting time.
To verify that your cable is working well, you can plug in another (working) cable and check if the issue is gone.
This way you will be able to determine whether your cable is working by connecting your PC and your router.
If the cable is functional, an orange light will start blinking in both of its ends.
This is the most secure way to learn if an Ethernet cable is working because you won’t know if the port’s working if you plug it into the port.
Xfinity Ethernet Port
After checking whether your ethernet cable works, your next step includes troubleshooting your ethernet port.
If you are here we assume that your Ethernet cable is working perfectly, and it would be an easy job to determine the functionality of the port. Simply plug it in and you will be able to tell right away if it is working or not.
As we have mentioned above, flickering lights at each end of the Ethernet cable will indicate the functionality.
If they are blinking, you are good, but if they aren’t, you might have to call a technician to take a look at your Ethernet port.
Despite all of your efforts, a more complex malfunction with the Ethernet port might be irreparable.
Although, there could be a few more simple things you could do to attempt to repair the port we are going to share those further in the post.
Xfinity Ethernet Router
The last component of your Xfinity ethernet configuration that might cause malfunctions is the router.
The router receiver & transmits Wi-Fi single throughout your whole household and just a slight issue might prevent him from doing so.
To fix the Xfinity ethernet router not working, we would include a few simple steps that will refresh & restart your router which will hopefully deal with any malfunctions.
Shall we get started?
How To Fix Xfinity Ethernet Not Working?
Now that you are familiar with the three main reasons we shall proceed to the troubleshooting part of this post.
Each method we will share with you will be specifically related to one of the components in your configuration so don’t skip a method.
Method #1 Reboot Router
The most common method of all will be to restart & power cycle your router.
We’ve figured that you have already attempted to restart your router so this is exactly why we have included the power cycle approach which is slightly different from a basic restart.
Here are the steps to perform a power cycle correctly:
- Turn off your router using the power button located on the backside.
- Unplug the power cable from the power source.
- Wait for at least 3-5 minutes for the best result at the power cycle.
- Plug the power cable back into the power source.
- Check if your Xfinity ethernet is functional now.
We have to inform you that the cooldown time we have mentioned above is of great importance to be respected.
Otherwise, your router won’t be able to refresh the incoming packets and will proceed with the same flow if turned on immediately so be patient!
Method #2 Replace Ethernet Cable
It is well known for similar issues to be related to the Ethernet cable itself. Even if there is a slight malfunction with the internal wiring of the cable you would still experience internet outages.
Our best advice would be to change your Ethernet cable as soon as you start to suspect it is having such issues.
After all, one ethernet cable wouldn’t cost much but it could damage the port after a while, so make sure to replace it right away if you have any concerns.
Method #3 Replace Ethernet Port
Another good approach with the Xfinity Ethernet port isn’t working issue would be to replace the port.
Many guidelines admit that changing the port should be one of the first things to attempt whenever you are suffering from similar malfunctions.
Simply choose one of the yellow ports and none of them turn out functional, plug the cable into the blue slot.
If the issue persists, by calling your internet & router provider you will be able to determine whether the ports on the device are working or not.
If you are informed that their functionality is compromised, you might have to make some purchases
Sadly, only a specialized technician will be able to tell and troubleshoot the ports located within your device so make sure to leave that as your last option.
Method #4 Troubleshoot Ethernet
To make sure that you have tried everything that depends on you, down below we’ve included a variety of ways to troubleshoot Ethernet on Windows 10.
There are plenty of things you could do that have a good chance of resolving the issue and are easy to execute at the same time.
Perform the following actions:
- Disable VPN and Firewall software on your PC.
- Identify any malware and harmful viruses.\
- Verify the functionality of the latest drivers for Ethernet.
- Check the connection status.
- Rollback network adapter.
If none of this works, make sure to run the Windows 10 Ethernet troubleshooter.
It will be able to inform you of malfunctions specifically related to your configuration and hopefully grant you with some proven to work tips.
If nothing works, you can freely call your network supplier and share what you have tried in this post.
We think that this is enough to save both yourselves time and get to a conclusion sooner.
If you still haven’t tried with a working Ethernet cable, now is the time to do so and completely exclude this possibility.
