How To Troubleshoot Comcast Xfinity Wi-Fi Not Working But Cable Is?

I wouldn’t say I like the thought of losing my internet connection at any time. Whether it’s during a live match, a zoom meeting, or while watching my favorite program on Netflix, I’m always on the go.

What’s worse is that your cable television continues to function normally even though they are connected to the same network, leaving you perplexed as to what exactly is wrong with your Wi-Fi.

Once I determined that it wasn’t a case of being connected to Wi-Fi but not having Internet access, I went out to find a solution to the problem.

If you are a Comcast customer, I’m sure you’ve experienced these service disruptions that have interfered with your productivity.

I’ve done quite a bit of troubleshooting for this myself, and I’ve come across some DIY solutions that I’d like to share with you after spending many hours researching the issue online.

Repairing your Comcast Xfinity Wi-Fi that isn’t working even when the cable is connected, as well as testing a different ethernet cable, and checking for splitter damage and Comcast internet outages, will help you resolve your problem.

Currently, most of us utilize the modem and router that our internet service provider supplies us with. Still, it isn’t the best option because we are effectively paying our ISP to “rent” a piece of equipment that isn’t very useful in the first place.

After all, researching wireless networking and price can take a significant amount of time. Therefore, cable Internet service providers such as Comcast Xfinity are necessary.

Despite being far less expensive, it still has its share of problems now and then. But don’t worry, I’m here to help you through any connectivity issues you may be experiencing with your Comcast.

When your Comcast Wi-Fi is not working at home, there are a few things you may do on your own before calling a local technician or Comcast Customer Care for assistance.

Check For Comcast Internet Outages

If your Xfinity service isn’t working, the first thing to do is check if there is a service outage in your locality. To do this:

1. To access Services, log in to My Account and scroll down to the bottom of the Overview page. Then select the Status Center link from the drop-down menu.
2. Select the Devices tab at the top of the My Account page, then select the Status Center link under Common Solutions from the drop-down menu.

A banner at the top of the page will tell you of any outages in your area.

1. Outages limited to a single service will be marked with a red status. This indicates that they are already aware of the problem and are working to resolve it.

When all else fails, try using the Xfinity Statu Centre to diagnose the problem. 

1. If the status of all of your services is green, this indicates that there have been no recorded outages in your area.
2. Another option of checking for outages is to use the Comcast Outage Map, which may be found here. Then, navigate to the Status Center and click the View Outage Map icon at the bottom of the page. The map shows the current status of your service address as well as outages in the surrounding region.

1. To examine outage information for a specific place, choose an icon on the map and click it. On the left-hand side of the page, you will see information on which Xfinity services are affected, what type of outage is occurring, the number of houses affected, and the estimated time it will take to resolve the problem.

Reset your router

Yes, the all-powerful restart/reboot option is available. If any of your devices are experiencing problems at any point, turning them off and back on is the best course of action.

It works the majority of the time, and your Wi-Fi is no exception to this rule.

Using the reset button on your electronic gadgets, you can repair small issues with them. This is because resetting a device returns it to its default state, eliminating any background programs that may be causing the problem.

The Xfinity My Account app or the Xfinity app can be used to perform a simple reset on your modem to get it back up and running.

If the modem restart procedure does not resolve your problem, you may choose to consider the following alternatives:

Troubleshoot Internet through My Account

1. Select the Internet Service tab from the My Account drop-down menu.
2. Select Devices from the drop-down menu. Locate the modem and select Restart Modem from the drop-down menu.
3. Select Start Troubleshooting to begin the modem restart process. 4. This process can take up to seven minutes to complete. During this time, your internet connection will be unavailable.

Troubleshoot Internet through the Xfinity My Account app

1. Launch the Xfinity My Account application.
2. Scroll to the bottom of the page and click on the Internet tile.
3. Select your modem from the drop-down menu and then press Restart this device.

Make sure all dues are cleared.

Check to see that all of your bills have been paid and that you have no outstanding amounts due.

Also, check to see whether you have reached your data cap, and if you have, consider changing to a better plan that meets your needs or simply recharging your current plan.

Consequently, you should go online and pay it if you owe money. You can also set up automatic payments to avoid a repeat of this issue in the future.

Check Your Splitter for Damage

A splitter is a piece of equipment used to divide a cable signal between two or more different devices.

Upon receiving signals from the antennas, they gather and distribute them to each output port.

This is how Comcast Wi-Fi and Cable TV systems operate — by dividing the signal between the Wi-Fi router and the TV receiver, respectively.

This means that if a splitter becomes faulty or worn out, the signal to your Wi-Fi router (assuming that it is the cable that has been damaged) could be hindered.

Meanwhile, the perfectly good physical cable can still carry TV signals, which is why the Cable TV system continues to function properly.

Try a different Ethernet port.

The majority of the time, it is a hardware problem. As with any electronic device, Ethernet ports degrade over time, and they can also be destroyed by vermin and other animals.

Consequently, try plugging your cable into a different Ethernet port to see if that solves the problem.

It’s also conceivable that other issues contribute to your Xfinity Ethernet not functioning properly.

Buy a new router—or move it.

The majority of us have our modems installed in a prominent area in our homes. However, depending on the property’s geographical location, this may not always be the most useful site for the house.

Likely, you’re simply disconnecting over and over again because you’re not close enough to each other to feel comfortable.

That is why I recommend that you purchase an additional router that you can use in “bridge mode” to connect to your existing modem and then position it in the room where you require the highest signal.

However, if you don’t configure it properly, you’ll be unable to connect to the Internet even when using Xfinity bridge mode.

Also, there are situations when the modem you are using is not the most compatible with your Internet Service Provider and is incapable of supporting the quickest speeds for your own devices.

Perhaps you should consider returning your modem/router to your service provider, purchasing a new one compatible with your ISP and the service you are paying for, and combining it with a high-quality wireless router instead.

This type of DIY setup is always beneficial in terms of longevity.

Contact Support

Now, if NONE of the methods listed above work for you and you’re still having trouble connecting to the Internet, your best and last option is to contact customer service.

Contact Comcast’s customer service and explain your situation to them clearly and concisely. Then, follow their recommendations.

Get your Comcast Wi-Fi Working Again

One thing you can do to keep an eye on your Wi-Fi performance is to run speed tests regularly, both for surfing and for downloading files.

Also, try to keep your wires, modems, and routers clean and clear of dust, as well as away from any pests.

Please keep in mind that by purchasing an Xfinity compliant router or an Xfinity Voice Modem that is tailored to your specific requirements, you can significantly improve your wireless experience.

It is recommended that you choose a router that is as least as fast as the devices you currently own.

If you choose to replace your existing service, make sure to follow the Xfinity Early Termination Procedure to avoid incurring cancellation fees.
