Comcast Xfinity WI-FI Not Working but Cable Is: How to Troubleshoot

I hate to lose my internet connection at any given point. Be it during a live match, a zoom meeting, or while streaming my favorite show. What’s worse is that your cable tv is still working fine even though they share the same connection, which keeps you wondering what on earth is up with your wifi. Once I confirmed that I wasn’t connected to wifi without Internet Access, I set about trying to resolve the issue. If you are a Comcast user, I’m sure you’ve had these outages that hinder your workflow.

Having done quite a bit of troubleshooting for this myself, I have some DIY solutions for you that I came across after putting in hours online to research the problem. You can solve your Comcast Xfinity wifi not working even when the cable is resetting your router, try a different ethernet cable, and check for splitter damage and Comcast internet outages.

These days, most of us use the modem and router that our internet service provider provides us with, but that’s not so ideal—because the mode of payment is through ISP that sells a product as a second-hand item. But then again, it’s time-consuming to research wireless networking and pricing. So that’s where cable Internet providers like Comcast Xfinity come in.

Comparatively cheaper, though, it still has its issues now and then. But fret not since I’m here to guide you through any connectivity issue your Comcast faces. When your Comcast wifi is down at home, there are some things you can do by yourself before you give up and call a local technician or Comcast Customer Care. The article below shows the solutions to the Comcast problem, the frequently asked questions, and the conclusion.

Solutions for the Comcast Xfinity wifi are not working, but the cable is working

1. 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. Sign in to My Account and scroll down to Services on the Overview page. Then click on the Status Center link to get access to the main menu.

2. Click on the Devices tab at the top of the My Account page, then click the Status Center link under Common Solutions.

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

1. Outages that only affect one service will show a red status. which means they’re already aware of the outage and are trying to fix it.

2. If this troubleshooting doesn’t work, try using Xfinity Statu Centre. If all of your services show a green status, there are no reported outages in your area.

3. Another method of checking for outages is using the Comcast Outage Map. To do this, Go to the Status Center, scroll down, and click the View Outage Map button. The map displays your service address status and outages in the surrounding areas.

4.  Click an icon on the map to view outage information for that location. On the left side, you will be provided with information regarding which Xfinity services are impacted, what kind of outage, the number of homes affected, and the approximate time to fix the issue.

2. Reset your router

Reset your router

Yes, the almighty restart/reboot option. At any point, if any devices are malfunctioning, switching them off and back on is the way to go. It works most of the time, and your wifi is no exception.

You can resolve minor issues with electronic devices by resetting them. It is because resetting a device brings it to its blank state, clearing any background processes that lead to the issue.

You can perform a quick reset on your modem using the Xfinity My Account app or the Xfinity app. If the modem restart process does not solve your issue, some other options that you can try are;

  • Troubleshoot Internet through My Account

1. Go to the Internet Service tab in My Account

2. Scroll down to Devices. Find the modem and select Restart Modem.

3. Select Start Troubleshooting to begin your modem restart. It can take up to seven minutes. Your internet will not be active during this process.

  • Troubleshoot internet through the Xfinity My Account app

1. Install the Xfinity application on the smartphone that it connects with the other devices.

2. Open the Xfinity My Account app.

3.  Scroll down and select the Internet tile.

4. Select your modem, and then press Restart this device.

3. Make sure all dues are cleared

Make sure your bills are paid, and you have no outstanding amount due. Also, check if you have exhausted your data cap, and if you have, consider upgrading to a superior plan according to your need or simply recharging your existing plan. So if you have an outstanding amount, go online and settle it. You can even opt for auto payments to avoid a similar situation in the future.

4. Check Your Splitter for Damage

Check Your Splitter for Damage

A splitter is a device used to split a cable signal between two or more devices. They collect incoming signals from the antennas and distribute them to each output port. It is how Comcast wifi and Cable TVs work – by splitting the signal between the wifi router and the TV receiver.

So if you have a bad or worn-out splitter that could potentially obstruct the flow of signal to your wifi router (if that’s the cable that is damaged). Meanwhile, the perfectly good physical cable can still carry TV signals, and that’s why the Cable TV works.

5. Try a different Ethernet port

More often than not, it’s a hardware issue. Ethernet ports tend to wear out over time and can also be damaged by pests and pets. So plug your cable into a different Ethernet port and see if it does the trick. It’s also possible there are other factors behind your Xfinity Ethernet not working.

6. Buy a new router—or move it

Buy a new router—or move it

Most of us have our modems placed in a central location at home. But sometimes, this isn’t necessarily the most optimal location depending upon the geography of the house. You may be just disconnecting over and over because you’re not close enough.

That’s why I suggest getting an extra router that you can connect to your existing modem using “bridge mode” and place it in the room where you need the strongest signal. Also, sometimes the modem you use isn’t the most compatible with your Internet Service Provider and cannot work with the devices some users have that have faster speed.

7. Contact Support

Now, if NONE of the solutions mentioned above work for you and you’re still struggling to reach the internet, then your best and final bet is customer support.  Contact Comcast’s customer support and explain your problem to them clearly and concisely and follow their advice.

8. Get your Comcast wifi Working Again

You can always keep an eye on your wifi performance by running speed tests, both for browsing and downloading. Also, try to keep your cables, modems, and routers dust-free and away from pests.

Keep in mind that you can make your wifi experience a whole lot better by getting an Xfinity compatible router or Xfinity Voice Modem that is optimal for your needs. It would be best to get a router that is as fast as the devices you own. If you go down the replacement route, ensure to go through the Xfinity Early Termination Procedure to avoid cancelation fees.

Frequently Asked Questions:

  • What do I do if my wifi is connected but has no Internet access?

“No Internet” means that a device has successfully connected to your wifi router, but something is preventing it from connecting to the internet over wifi. A little DIY troubleshooting will help identify and solve the problem.

  • Why does my Comcast wifi keep disconnecting?

Loose cables and signal interference may be the reason why your Comcast wifi keeps disconnecting. Apart from this, some maintenance or outage in the area could also be the reason.

The actual problem might lie with your internet speed and bandwidth usage. It might be much higher than you think, and thus your internet keeps crashing. Try upgrading to a superior plan with higher bandwidth, and your internet will quit crashing.

The problems with Comcast can be a result of the internet connection ports, router, and damages to some parts of the Xfinity device. In some cases, the problems arise because the user fails to check on the machine for any damages frequently.

 Therefore, follow the article to help you fix the problems with your Comcast Xfinity wifi not working, but the cable is working. Remember to consult a technician if the whole process fails to work on your Xfinity.
