What happens after you order Xfinity

Once you have ordered Xfinity internet service, Comcast will schedule a technician to visit your home and install the equipment. This visit typically happens within 5 to 10 business days, though timing varies by location and current demand. The technician will run a cable line from the street to your home, set up the modem and router, and test the connection before leaving.

You do not need to do anything before the technician arrives except make sure someone is home during the scheduled window. The technician brings all the equipment you need — the modem, router, and cables — so you do not have to buy anything separately. If you already have Comcast cable or phone service, the installation is usually faster because the line may already be in place.

Key Takeaways

  • A Comcast technician will install your modem and router during a scheduled home visit, which typically takes 30 minutes to an hour.
  • You will receive a Wi-Fi network name and password from the technician or in your welcome materials, which you use to connect devices wirelessly.
  • The modem and router should be placed in a central location in your home, away from metal objects and thick walls, for the strongest signal.
  • You can manage your account, check your bill, and restart your equipment through the Xfinity My Account app or website.
  • If your internet stops working, restart the modem by unplugging it for 30 seconds before contacting Comcast support.

Setting up your modem and router

The technician will plug in your modem and router and show you how they work before leaving. The modem is the device that connects to the cable line coming into your home and converts that signal into internet. The router broadcasts that internet wirelessly to your phones, tablets, computers, and other devices. In most cases, Xfinity provides a combined modem-router unit, so you only have one box to manage.

The technician will give you a label with your Wi-Fi network name (also called SSID) and password written on it. Write this information down or take a photo, because you will need it to connect each device. The network name usually starts with "XFINITY" or "Comcast" followed by numbers. Keep the password somewhere safe — you will need it whenever you add a new device to your network.

Place your modem and router in a central location in your home, ideally on a shelf or table rather than on the floor or in a cabinet. Avoid placing it near metal objects, microwaves, or thick walls, as these can weaken the signal. If your home is large or has multiple floors, you may want to ask the technician where the best location would be during installation.

Connecting your devices to Wi-Fi

To connect a phone, tablet, or computer to your Xfinity network, go to the Wi-Fi settings on that device and look for your network name in the list of available networks. Tap or click on it, then enter the password exactly as it appears on your label — passwords are case-sensitive, so uppercase and lowercase letters matter. Once you enter the password correctly, the device will connect and you should see an internet connection symbol appear.

If a device does not connect after you enter the password, double-check that you typed it correctly. A common mistake is confusing the letter O with the number 0, or the letter I with the number 1. If you still cannot connect, restart the device and try again. If multiple devices cannot connect, restart your modem by unplugging it for 30 seconds, waiting for all the lights to come back on, and then trying to connect again.

Understanding your Xfinity account

Comcast will send you a welcome email with your account number and instructions for setting up online access. You can log into the Xfinity My Account app or website using your email address and a password you create. From there, you can view your bill, check your internet speed, restart your equipment remotely, and contact support if you have problems.

Your monthly bill will show your internet service charge, any equipment rental fees, and taxes. Xfinity charges a monthly fee for renting the modem and router — you can avoid this fee by purchasing your own compatible equipment, though the technician will still need to set up it during installation. Check your bill each month to make sure you are being charged the rate you agreed to when you ordered.

Restarting your equipment when something goes wrong

If your internet stops working or becomes very slow, the first step is always to restart your modem. Unplug the power cable from the back of the modem, wait 30 seconds, and plug it back in. The lights on the modem will blink as it restarts — this usually takes 2 to 3 minutes. Once all the lights are steady, try using the internet again. This straightforward step fixes the problem about 70 percent of the time.

If restarting does not work, check that the cable coming into your modem from the wall is plugged in firmly. If you have a separate router, also make sure the cable connecting the modem to the router is find. If everything is plugged in and the modem still does not work, you can restart it remotely through the Xfinity My Account app by going to the "Equipment" section and selecting "Restart Modem." If the problem continues after a restart, contact Comcast support through the app or by phone.

Improving your Wi-Fi signal

If some rooms in your home have weak Wi-Fi signal, try moving your modem and router to a more central location. Signal travels better through open space than through walls, so a location in the middle of your home will reach more rooms than one in a corner. If you cannot move the equipment, you can purchase a Wi-Fi extender or mesh system to boost the signal in distant areas — these are sold separately and work with Xfinity equipment.

Xfinity also offers a service called "xFi Pods" — small devices you place in other rooms to extend your Wi-Fi coverage. These are optional and cost extra, but they can help if you have a large home or thick walls that block the signal. Ask the technician during installation whether your home might benefit from additional coverage, or check the Xfinity website to see if pods are available in your area.

What to do if you need to move or cancel service

If you move to a new home, contact Xfinity at least two weeks before you leave to schedule a disconnect at your current address and a new installation at your new address. The technician will remove the equipment from your old home and return it to Comcast. At your new home, a technician will install new equipment and set everything up again. You may be able to keep the same account and just transfer the service, depending on whether Xfinity serves your new address.

If you want to cancel your service, call Comcast or use the Xfinity My Account app to request a disconnect. Comcast will schedule a technician to remove the equipment, usually within 5 to 10 business days. You must return all equipment — the modem, router, and any cables — or you may be charged a fee. Keep your account number and any receipts showing you returned the equipment.

Frequently Asked Questions

Can I use my own modem and router instead of renting Xfinity equipment?

Yes, you can purchase a compatible modem and router separately and avoid the monthly rental fee. Comcast maintains a list of approved equipment on its website. You will still need a technician to set up your service, and they will need to configure your equipment during the installation visit. This option saves money over time if you plan to keep the service for more than a year or two.

How fast is Xfinity internet, and will I get the speed I paid for?

Xfinity offers different speed tiers depending on your location, ranging from around 25 Mbps to 1,200 Mbps. The speed you receive depends on the plan you ordered, the quality of the cable line to your home, and how many devices are using the internet at once. You can check your actual speed through the Xfinity My Account app. If you consistently get much slower speeds than you paid for, contact support to have the line tested.

What should I do if the technician does not show up for my installation?

Check the Xfinity My Account app or your email for any updates about the appointment. If the appointment was rescheduled without your knowledge, you will see a new date and time. If the technician straightforward did not arrive during the scheduled window, contact Comcast support when ready to reschedule. You may be offered a credit for the missed appointment.

Is my Xfinity Wi-Fi password the same as my account password?

No, they are different. Your Wi-Fi password is what you use to connect devices to the internet wirelessly — it is printed on a label on your modem. Your account password is what you use to log into the Xfinity My Account app or website to manage your bill and account. You can change your Wi-Fi password through the Xfinity app if you want to, but you do not need to.

Can I get a faster internet speed later if I need it?

Yes, you can contact Comcast to upgrade to a faster plan at any time. Faster speeds may cost more per month, and you may need a technician visit to upgrade the equipment, depending on which plan you choose. Check the Xfinity website or call to see what speeds are available at your address and what the upgrade would cost.
