Xfinity Wi-Fi Keeps Cutting Out

Xfinity is among the leading internet service providers in the cable connections field. The speeds allow for heavy internet usage and fast connectivity. However, like every other electronic device, their gadgets malfunction, and services drop from time to time. Xfinity users face a common problem of their internet dropping without any discernible reason. Therefore, this article looks at the causes and what you can do to stabilize your network and enjoy Xfinity services.


Restart Your Gateway and Run the Troubleshooter

In most instances, the malfunction of electronic devices is caused by them being on for too long. The gateway or router (depending on your setup) can also have a temporary software problem.

Consider restarting all the devices that use Comcast internet and reestablishing the connections.

If you manually restart the network devices, give them a few minutes before switching them on.

You can restart an Xfinity gateway through the Xfinity app or your account.

Once you have logged into your account, go to the internet services tab and scroll to devices.

Locate the gateway and select restart the modem. Select Start Troubleshooting to commence the Restart and troubleshooting process.


Alternatively, you can use the Xfinity app for the same troubleshooting process. To trigger troubleshooting, click on the internet under the overview tab.

Tap on the gateway device with issues and select Restart this device for iPhone users and troubleshoot for android users.

Tap on Restart Device to confirm the Restart and wait. Troubleshooting your device should take at least seven minutes.


Cable Connections

Due to long-term usage, it is easy for the various cable connections to loosen up or wear out. The cables going into your Xfinity gateway should be in good condition and firmly linked to respective ports.

To rule out the possibility of a poor connection being the source of your frustrations, inspect all cables on the connection. If you are using a third-party router and modem, ensure the connection between both devices is intact.

If you have reason to believe the cause could be the wiring, buy new ones and try reconnecting your devices. Purchasing new cables is worth the hassle, especially if the current ones are old.

Also, if your Cox cables have a splitter attached, remove it and connect the gateway directly to the wall outlet. Coax splitters can weaken the signal through leakages and, in turn, cause the Wi-Fi to constantly cut out.

Find out from neighbors who use the same ISP if their wireless connection behaves similarly. That way, you can determine if the cables in your residency have a problem.

While checking the cabling, remember to inspect the power cables too. A loose plug in an outlet can cause the gateway to keep going on and off.

You can contact Xfinity customer support, and they will send a technician to check on the cables running in the walls. However, it will take a considerable amount of time before you see a technician try out other solutions as you wait.

Move Closer to the Router/Gateway

Wireless internet connections require users to be close to the signal source. Reducing the distance would strengthen the signal, especially if there is any interruption between your device and signal source.

Therefore, ensure there are no thick boundaries between you and the router. Check if the signal behaves similarly on other devices to narrow down the interruption’s cause further.

If the problem is only on one device close enough to the router, check the device’s settings. Alternatively, the cause could be your gateway settings.

To avoid signal interruption, always place the Xfinity gateway in an open area away from cramped spaces.

Service Outage 

Service outages occur from time to time. They are notorious because they make you think your router has a problem, yet it works fine.

You can check for Xfinity service outages on the Xfinity status center or the app.

If your number is linked to your Comcast account, you can text OUT to 266278 (COMCST) for service outage updates.

If you recently made any changes to your Xfinity services, consult customer support to enquire whether you need any activation from their side. Some service upgrades require activation from Comcast’s end to work.

Disable the Xfinity Hotspot

Xfinity gateways allow other devices outside your home to use your gateway to access the internet. Your Wi-Fi could be dropping because the device you are using is alternating between the hotspot and your private wireless network.

The Xfinity Hotspot is usually named “xfinitywifi,” so check if your device is connecting to the correct network.

The devices connecting to your gateway’s hotspot do not use your bandwidth. However, they contribute to the number of devices relying on your gateway for a connection. Too many devices strain the gateway and could, in turn, cause Wi-Fi to keep dropping.

To disable the hotspot service via the app, tap on connect>see network. Scroll to Advanced settings>more and select Xfinity Wi-Fi hotspot.

Alternatively, use this link to go directly to the hotspot settings on your Xfinity account and tap turn off. You might need to enter your Xfinity ID and password first.

If you can not trace the settings, chances are your gateway does not support the Xfinity hotspot settings.

Change the Wi-Fi bands

Some Xfinity gateways have up to three wireless bands. They include one 2.4GHz and up to two 5GHz bands. The different bands work simultaneously to provide a stable wireless connection; however, some devices only support the 2.4GHz band.

An incompatible band may be active while the 2.4GHz is deactivated.

Try shifting to a lower frequency band or deactivating higher frequency bands to remedy the situation.

To toggle between the available bands, log into the Xfinity router’s administration page and navigate to gateway>connection> Wi-Fi.


Click edit on the 5GHz bands and tap disable. Next select Edit on the 2.4GHz and select enable if it was inactive. Save the settings and reconnect your device.

Disconnect Some Devices

It is hard to take note of all the devices that have access to your wireless connection. Some may have connection issues if the devices overburden your gateway or router.

Generally, Xfinity limits the number of devices connecting to the advanced gateway to 100.

If Wi-Fi keeps cutting out on a single device, try disconnecting other devices on the same network. Now connect the device with problems and observe if it stops cutting out.

If that solves the problem, check on the gateway settings to see if there’s a limit on the number of devices connecting wirelessly.

Get a New Router/Gateway

Xfinity is big on upgrades hence why there is a variety of gateways. The upgrades are necessary for service provision; however, one can do without them. Therefore, many users do not bother to send in their old models for new ones as long as the old ones work.

Some software upgrades fix incompatibility issues between the gateways and new operating systems on various devices. Therefore, if your gateway is a couple of versions behind the most recent version, consider sending it in for a new one.

Power Surges

Although a rare occurrence, power surges can cause the signal to fluctuate. If you live in an old building that has gone for long periods without maintenance, the power equipment could be outdated.

Check if the connection on other devices is constantly going on and off. If it is, then you may have a power problem. To remedy this, you can use an Uninterrupted Power Supply or a surge protector to have constant stable power to your devices.

If the surges cause fluctuation, have an electrician update your electrical wiring as a long-lasting solution.

Temporarily Disable Security Programs

Security software such as antivirus and firewalls can interfere with the wireless connection.

Disable firewalls and the antivirus on your device, especially if Wi-Fi keeps dropping on a particular device.

Signal Interference

Some home electronic devices like microwaves use the same frequency as your wireless connection.

Rule out signal interference by switching appliances such as the fridge and baby monitors and observe your connection.

Move the Wi-Fi source to a new location further from such devices if it stabilizes.

Other sources of signal interference include;

  • Baby monitors
  • Cordless phones
  • Water dispensers and large amounts of water.

If none of the solutions above work for you, the last option is to call Xfinity to send a technician your way. Whoever you talk to will most likely suggest the above solutions; therefore, insist they send someone to try more technical solutions.

If you manage to restore your connection, note down the solution that worked if the problem reoccurs.
