Although annoying, this issue can happen occasionally and should be straightforward to fix.

To fix the issue, first check the lights on your router and modem to see if they are indicating an issue.

If the light is blinking white or solid red, there is an issue with the internet connectivity.

Next, you can check if there is local outage, update your router firmware, restart or reset your device.

Below, we provide a step-by-step guide on all the solutions you can try to fix the Xfinity network connection issue.

Why Does My Xfinity Internet Keep Disconnecting?

When your Xfinity internet is disconnected, it is mostly not an issue with the router device itself, but other reasons such as:

Interference with the signal.
Loose and faulty cables.
Distance of WiFi.
Outage with the service.

How to Stop Your Xfinity Internet from Cutting Out

Below we outline 14 steps you can take to prevent your Xfinity internet from disconnecting. You can follow the steps in order to ensure you quickly find a solution.

1. Check the light on your router and modem

The different lights on your router show various problems. The LEDs on your router or modem will tell you if there is something wrong when your internet keeps disconnecting.

On Xfinity devices, the light types and corresponding status are:

Solid white – device is fully operational.
Blinking white – device has unstable internet.
Solid red – device has no internet connection.
Blinking blue – device is in WPS pairing mode.

2. Look for Xfinity service outage

If your entire local area does not have internet, then the lack of internet connection is not due to your router or modem.

Probably, Xfinity has an outage in your region and you can confirm this by signing in to your account on xfinity.com/support/status.

If your area has an outage, Xfinity will give you an estimated time when they bring back the service.

3. Check for Interference

If the lights on your router and modem are fine and there is no service outage, then there may be something causing interference in your home.

These may include baby monitors, microwaves, landline wireless phones, Bluetooth devices, or fluorescent lights.

Your router’s 2.4 GHz channel is more prone to interference from the devices mentioned above, therefore, switch to 5 GHz if you can.

If not, you should move your router to a different location in your house. Or remove/reduce the device that is bringing the interference.

If this does not work, then you may need to check if your router needs a firmware update.

4. Update your router’s firmware

Updating your router’s firmware may be the solution to your disconnected Xfinity internet. Your router is controlled by software known as the firmware and like any software, it may have patches and updates.

The following are the steps to update your firmware:

Log into the admin page of your router.
Check for a tab known as ‘Update’, ‘Router Upgrade’, or ‘Firmware’.
Follow the steps to update the firmware.

If the modem and router are separate, remember that a firmware update can sometimes break their compatibility.

Therefore, if your modem is older, you may want to skip this step for now until you replace it with a Xfinity compatible modem.

However, if you have a Modem/router combo device, you will not have this issue.

5. Check your cables

If your Xfinity internet keeps cutting out, then your cables could be the issue. A loose coaxial cable, which connects the wall outlet and the modem, is the most common problem.

To fix a coaxial cable, you need to unscrew it from the modem. Then tightly screw it back in. Try a different cable if it is still loose, and if it does not work you should contact Xfinity.

Splitters are another cable problem as it takes one signal and divides it into two which causes issues with the internet connection. To fix this problem, you need to buy a new splitter from Xfinity.

Additionally, you should check the Ethernet cables to ensure that they are undamaged, clicked into the ports, and snug.

6. Check your router’s power settings

Your Xfinity router may have issues with some types of internet connections if it is set to ‘Power Saving Mode’.

Therefore, you should turn the Power Saving Mode off by logging into the admin page of your router. Then find a tab named ‘Power Management’ or ‘Power’ and turn it off.

When you are finished with these changes, you should reboot your router and modem. This will enable the changes to be applied and any connection issues will be fixed.

7. Move your router

If you are still having trouble connecting to the internet, the problem may be your router’s location. If your router is near a window, in a corner, or behind a TV, these can all lead to issues with your WiFi signal.

The general rule is you should place your router in the center of your house, as this will help make the signal as strong as possible.

Also, you can move the router to a different level. For example, if it is on the shelf, move it to the floor and if it is on the floor, move it to the shelf.

8. Dust off the router

If your router is still not connecting to the internet, maybe you should give it a good cleaning. When dust accumulates on the vents, there will be issues with airflow leading to overheating which the result in the router being damaged.

To clean your router, first, unplug it from the power supply. Dust off the vents using a can of compressed air and ensure that you do not touch any internal circuit boards. Once cleaned, plug the router back in and check if the issue is fixed.

9. Change your DNS server

Are you still having trouble connecting to your Xfinity internet? You can change your DNS, but you need to be careful as it is an advanced solution.

The purpose of a DNS server is to change website names to IP addresses, and if it is overloaded or not working correctly, your internet connection will have issues.

There are different options for DNS servers, but the Google DNS server is recommended.

To change it, you need to log into the admin page of your router and find a section called ‘WAN’, ‘Internet’, or ‘Network’ and click on it to get the option of changing your DNS server to 8.8.8.8.

10. Change your router’s wireless mode or channel

The next thing that you can do to help restore the internet connection is to change the channel of your router. The channel is the frequency used by your router to communicate with the devices.

The connection will be slowed down or there will be interference if other devices use the same channel. Your router can also disconnect.

Changing your channel is easy and what you need to do is log into the admin page and find a tab named ‘Radio’, WiFi’, or ‘Wireless’. Look for the option of changing the channel and select a different channel.

Additionally, you can use a different wireless mode, meaning changing the protocol used by your router to pass information to your devices. 802.11ax (WiFi 6) and 802.11ac (WiFi 5) are the most common modes.

Your router’s internet connection may be restored if you change the setting to WiFi 6 from WiFi 5 as the previous one has better optimization and can handle more devices.

You can choose a different wireless mode in the ‘Wireless’ ‘Radio’ or ‘WiFi’ section of your admin web page.

After making these changes, reboot the router and modem. This should solve the problem and help you with your connection.

11. Remove connected devices

The next thing that you can do is disconnect all the devices connected to your router’s network including smart TVs, computers, smartphones, gaming consoles, etc.

Your router could be overloaded if it is connected to too many devices leading to issues with internet connection.

Therefore, check for any devices that are not in use and disconnect them and see if this solves the problem. Once finished, start reconnecting the devices one by one to find which one is causing the issue.

12. Restart or reset your router

Try resetting or restarting your router and modem or router/modem combo if the problem is still there. Sometimes, this is all you need to do to fix the problem. If it does not work, you should hard reset your router.

13. Contact Xfinity support

If you have done all the steps mentioned above and the internet is still disconnected, your option at this stage is to contact customer care support. You can speak to the by phone or online through their website.

An expert or technician will walk you through some of the solutions to fix the problem, but if you are not able to fix it yourself, they will come to your home and fix it for you.

What causes a regional internet outage?

If your whole community has no internet access it is likely due to an outage with the internet network ‘backbone’. Internet service providers have thousands of backbone networks spread nationwide.

The purpose of these networks is to provide an exchange path for various smaller networks to interconnect.

If the backbone has an outage, a whole building or community will suffer an outage.

How Do I Fix The ‘failed to obtain IP address’ On Xfinity WiFi

The simplest way of solving the ‘failed to obtain IP address’ issue on your Xfinity WiFi is to restart your WiFi devices and reconnect them again.

If this does not work, you can forget the network and do a factory reset, or move closer to the networking device and try reconnecting again.

What’s the difference between a router and a modem?

The modem is a device that brings internet to the home from the internet service provider, while the router provides a local network within your home.

The modem uses a public IP address and WAN network to translate ISP signals into ones your devices can communicate with.

The router meanwhile uses local IP addresses and a LAN network to connect your devices. The router emits an internet connection either through an ethernet cable or wireless WiFi signal.

Traditionally, the router and modem come as two separate devices. However, the latest technology brings the two functions of a modem and router into one device. An example of this multi-functional machine is the Xfinity Wireless Gateway.
