How to Fix When Xfinity Self Setup Not Working?

Above we’ve learned some basics about the Xfinity self-installation process, what it does and how it works.

In the upcoming guide, we’ll be covering as many causes for the problem as possible, so make sure to give us your full attention and keep reading until the end.

Here are the best solutions you could find on the web!

Solution #1 Correct the Cable Setup

Assuming that you’ve gotten the all-in-one Xfinity package, you have been granted both a TV box and an internet modem.

Otherwise, you’ll only have a network modem, to use along with your router for the main internet supply.

You should go over the cable setup again, to make sure that everything regarding the wiring in your setup is correct.

Here’s how your cables should look like:

• Coaxial Cable connecting your TV Box/Modem with a Coax Outlet
• Power Adapters connecting your Xfinity equipment to power
• Ethernet Cable connecting your Xfinity modem to the router you already have

Generally, you could rent a router from Xfinity or use one you already own.

Either way, the connection remains standard and all you have to do is connect the modem and the router with an Ethernet cable. Make sure that the Ethernet is in the blue port on the back of your router.

Note: Xfinity equipment usually comes with a single coaxial cable to use for the connection.

Solution #2 Fix your Mobile’s Internet Connection

While completing the Xfinity self-install, your mobile must have a reliable WiFi/Cellular connection.

Otherwise, it’ll not be able to locate the Xfinity cable box/modem and get the device set up. This is because the Xfinity app requires the internet, in order to function.

• Your mobile must be close to the WiFi source, throughout the entire time!

Assuming you already have the Xfinity Mobile Application, it’s time to validate the WiFi of your mobile device.

Follow these steps to fix your mobile’s WiFi:

1. Go into your Mobile Settings.
2. (Optional) If connected to WiFi, navigate to the WiFi Menu and press the slider.
3. If using cellular on your mobile, disable the Mobile Data feature.
4. Wait for 60 seconds, while both the mobile data and the WiFi feature are disabled.
5. Re-enable the feature that connects your mobile to the internet.
6. Test…

If you still have the WiFi from your old internet service, or you’re only installing Xfinity’s TV package, the connection must be as strong as possible.

Note: Ensure that you have enough Mbps left in your plan if using mobile data!

Solution #3 Pay the Self-Installation Fee

When installing your Xfinity equipment, you’ll have two options:

• Professional Installation – 100$
• Self-Installation – 15$

You’ll still have to pay Xfinity if you want to complete the setup by yourself and save a hundred dollars.

This is because they fully lend you their equipment and this small fee works as somewhat of a cover if something goes wrong with the cable box/modem.

If you subscribed to Xfinity online and got your equipment delivered not long ago, you should verify that you’ve paid the self-installation fee.

If you haven’t paid it, Xfinity will consider your setup inactive or await technicians to come in and take care of it.

Here’s how to check/pay the Xfinity self-installation fee:

1. Access the Xfinity website.
2. Log in using your username/password.
3. Navigate to Subscriptions and check what pending taxes you have.

Note: If you’ve subscribed physically, you may have to go to a Comcast/Xfinity office.

Solution #4 Limit Installed Devices

Xfinity self-install not working is a problem that could be occurring due to the Device’s Limitations.

With self-install, you’ll have all the freedom to yourself, install as many Xfinity cable boxes as you want, and set up as many modems as you have.

Unfortunately, there is a particular device limitation that doesn’t allow you to install more than 4 Xfinity devices. Going over that count of devices and the service on some of the already-installed devices will go offline.

• There mustn’t be over 4 coaxial cables, connecting to your Xfinity devices!

Generally, users tend to get into that range by installing a single Xfinity modem, along with 3 TV boxes. This is a standard setup of the Xfinity services, for both internet and TV service.

Note: Stay under the limited device count in order for your Xfinity service to remain active!

Solution #5 Reinstall the Xfinity Mobile App

Since the Xfinity mobile app is what’s used to complete the Xfinity self-installation process, a problem with the platform may interrupt the setup.

A quick way to take care of this problem is to reinstall the application, by removing it and then downloading it again on your mobile device.

Follow these instructions to reinstall the Xfinity mobile app in easy steps:

1. Head into your Mobile Device Settings.
2. Navigate to “Applications” or “Storage”, based on the interface of your mobile device.
3. Tap the search field (if one is available) and do “Xfinity” to locate the app.
4. Once you’ve found the Xfinity application, highlight it.
5. Select “Uninstall” to start the removal of the app.
6. Wait until the Xfinity app has been successfully uninstalled.
7. Acquire the application again from the app store on your mobile device.
8. Wait for the app to get downloaded.
9. Launch the app and complete the Welcome Setup.

You could also try updating the Xfinity app before removing it from your device to determine if that’ll fix the problem.

Sometimes when the software of the app hasn’t been updated in a long time, it could start experiencing a variety of problems.

Tip: You should enable “Automatic Updates” for Xfinity so you don’t have to do it yourself.

Solution #6 Factory Reset the Xfinity TV Box/Modem

If nothing worked so far, then you should perform a factory reset on the equipment you’ve received from Xfinity.

Since they tend to lend out equipment that they’ve already given to customers, chances are that a fault could’ve come with the modem/TV box.

Even if using your own modem or TV box, it could’ve gotten bugged out due to your previous service, before getting Xfinity.

Let’s first learn how to reset an Xfinity TV box!

How to Reset Xfinity TV Box:

1. Locate the Power Button on your Xfinity TV Box.
2. Make sure that the box is plugged in.
3. Press and hold the power button for 10 seconds.
4. Let go of the button once that time has elapsed.
5. Wait for the TV box to reset.

How to Reset an Xfinity Modem:

1. Make sure that the modem is plugged in.
2. Locate the Reset Button Pinhole, on the back of the modem.
3. Use a toothpick or a paperclip to insert it into the pinhole.
4. Hold the button for 30 seconds.
5. Wait for your modem to go into reset mode.

No matter whether you reset your Xfinity TV Box or modem, the process will take around 1-2 minutes. During that time, do not interact with the device, to avoid canceling the process.

Alert: The factory reset will erase any customized settings on your Xfinity equipment.

Quick Recap:
