Comcast Xfinity’s customer service number is 1-800-XFINITY (or 1-800-934-6489).

If you’d rather not make a phone call, you can always live chat with a representative if that’s easier. (Sadly, introverts, there’s no Comcast Xfinity email to reach customer support—although you can reach them through text or social media if you prefer those routes. Some may be more effective than others, bone of them require you to chat on the phone.) 

If you have a complex service problem, we find the chat feature to be very slow and frustrating. You might also forget you’re chatting with someone, come back 10 minutes later, and the rep has already terminated the conversation.

By making the phone call, you could get your solution within a jiff.

If you need guidance in troubleshooting TV picture or signal quality issues, you can find some of your answers online at Xfinity’s support page. You can also find answers to general questions related to WiFi and internet connection issues.

Oh, and if you have a problem specific to Xfinity Mobile, here’s a nice phone service FAQ to help you out.

Also, as a Hail Mary move, you can always show up at an Xfinity store and request assistance. (The Xfinity app can help you find Xfinity stores nearby.) Demanding help in the flesh may not make you the favorite customer in the Comcast business portfolio, but at least it’s a direct way to get answers about your Xfinity service.

Just because you reach out to Comcast Xfinity customer service doesn’t guarantee that you’ll be connected to a real person. And in most cases, that’s a no-go.

So allow us to guide you through to a real person. Here we go.

When making the phone call to Comcast Xfinity's customer service at 1-800-XFINITY (or 1-800-934-6489), you’ll be prompted with automated menus.

First, they’re going to ask you to enter in your ZIP code, account number, or phone number, or ask you to indicate that you’re a new customer.

After that, the automated voice will push you to go online.

The voice will offer to send you the link to the Xfinity Customer Support Assistant (in other words, their virtual assistant) to answer “most common questions”.

Just say “no” a few times, and then you’ll be asked to verbally say what you need help with. Then you should be directed to a live agent (in other words, a live human).

Yes, Comcast Xfinity TV is available 24 hours of the day. Call them at 1-800-XFINITY or 1-800-934-6489 or chat live at www.xfinity.com/support.

They’ll be able to help you with most of your cable TV, WiFi, mobile, and internet service questions as well as help you with any buggy tech issues, or at least direct you to someone who can.

Unfortunately, there’s no concrete way of how to specifically get a call back from Comcast. We know that’s frustrating to hear as a Comcast customer.

But Comcast Xfinity says they will respond to you within 24 hours if you have any type of service problem, but you won’t be receiving that response if your service problem is under “extraordinary circumstances or where conditions are beyond our control.”

What Xfinity’s definition of “extraordinary circumstances” or “conditions beyond our control” are, well, we don’t know.

But we can assume that this means a power outage from weather conditions or a fallen power line.

If this isn’t the case, you should expect a response from an Xfinity customer service representative the next business day.

1-800-266-2278 appears to be a secondary Xfinity customer service number.

Although this number isn’t the same as Xfinity’s standard customer service number (1-800-XFINITY or 1-800-934-6489), in our experience, it’s still the same type of help.

With both numbers, the recordings and automated menus are exactly the same.

First and foremost, make sure your device is in fact connected to your in-home WiFi network.

Xfintiy says the most common way to fix internet service issues is to restart your modem.

The best way to restart your modem is to sign into your account, click on Services, scroll down to Devices, and click Restart Modem.

If this doesn’t work, you’ll be prompted to schedule an appointment with one of the technicians.

To get optimal WiFi coverage make sure your modem, or “Gateway” as Xfinity calls it, is in these ideal settings:

• Placed in an open space
• Placed in a central location of your home or near where WiFi is needed most
• Placed away from microwaves, refrigerators, TVs, and computer monitors

If your Gateway is already in its perfect little area, these factors could play a role in slow WiFi:

• You might have too many devices connected to your network
• The distance between your Gateway and your device

Your modem or router could be to blame.

Xfinity suggests upgrading your modem if it’s a generation or two behind. An upgrading modem will deliver the fastest broadband speeds.

This is important for any household that has several people working from home, streaming, or downloading at the same time.

Take a speed test to see if your router might be the problem.

After all of these FAQs, you might be wondering where Xfinity ranks when it comes to customer service performance among its competitors.

Well, according to the ACSI Telecommunications Report of 2021–2022, Xfinity service hasn’t gotten any better since its last ranking—but at least it hasn’t gotten any worse.
