Wondering how to setup Xfinity WiFi router? Well, stay with us until the end of this guide to learn all about your Xfinity equipment, how to set up your devices, and manage the network!
To begin with, connect the router to the power If it’s a router/modem combo, plug the router with the modem using Ethernet and connect it directly to the service outlet.
When the setup is ready, visit “xfinity.com/activate” to set up your internet.
Let’s first determine what type of Xfinity setup we’re dealing with!
How to Identify Your Equipment?
It’s first necessary to identify what equipment you’ve got from Xfinity.
Though the software setup is identical to the gateway/modem & router combo, you must lead the wiring alternatively!
How to Tell If I Have a WiFi Router & Modem Combo?
- Look at the back of the router and check if the Ethernet cable connects to a primary network device (modem).
- If the network device does not go straight into the service (coaxial) outlet, then you’re using a WiFi router and a modem!
Note: Routers typically have WiFi antennas coming out of the back panel!
How to Tell if I Have a Network Gateway?
- Check if your Xfinity network devices plug in straight with the service outlet. If your network device is standalone and there are no additional devices such as a modem, then you’re using a WiFi/Network gateway!
Note: Xfinity-manufactured gateways usually have a cubic form with no antennas coming out!
How to Connect Xfinity WiFi with Router & Modem Combo?
Notice: Renting equipment from Xfinity is optional.
You could use any gateway or router and modem combo with the Xfinity service, as long as it is applicable to WiFi functions.
Over the long run, some users prefer to save extra money by using equipment of their own!
1. Connect the Router to the Power
The first and most important task is to connect your modem and router to power.
Take out all of the equipment supplied by Xfinity from the delivery package and sort out all components you will need.
Required Xfinity Internet Components:
- A router and a modem (the modem may be optional)
- 1 or 2 power adapter cables
- 1 coaxial cable
- 1 Ethernet cable
Note: If you have both a router and a modem, then we will need two power adapters to work with the devices!
How to Connect Xfinity Router to Power?
- Place the router in an appropriate position.
- Install the power adapter’s A/C end into the power.
- Plug the other end of the cable into your router.
- Wait for the router’s LEDs to come on.
Notice: If the router/modem’s LEDs aren’t coming on, verify that there’s power!
2. Install the Necessary Wiring!
With a separate Xfinity router and modem, there must be one Ethernet cable connection in addition, to wiring up the devices.
The modem must be capable of transferring information to the router at all times, so the router could host the WiFi network and deliver internet!
- The modem must be connected to a service outlet in your house!
How to Connect Modem to Service Outlet:
- Connect the first end of the coax cable to the Xfinity modem.
- Place the modem near a service outlet in your house.
- Plug the other end of the coax into the coaxial outlet.
How to Connect Xfinity Router to Modem:
- Take out the Ethernet cable from your Xfinity package.
- Position the router near our Xfinity modem device.
- Connect the first end of the cable to your router’s blue port.
- Plug the other end of the cable into your Xfinity modem.
Note: If there’s active service in the coaxial outlet of your household, all LEDs of the Xfinity modem and/or router should come on and flash in green light!
3. Connect with your Xfinity Device
Activating your Xfinity internet must be done through a PC or laptop, connected to the Xfinity-serviced router or modem.
Fortunately, Xfinity has made it possible to connect with your Xfinity device in two ways during the early stages of the setup!
How to Connect via Wi-Fi?
Alert: To connect via WiFi, you’ll need the Xfinity router password.
If the network device is supplied from Xfinity, look for a line that starts with “PW” on a sticker at the bottom panel and copy the code.
The “PW” field is usually situated next to the “SSID” – service set identifier.
- Launch the WiFi settings on your PC/laptop device.
- Look for a network that starts with “Xfinity”.
- Select the Xfinity network and type the password.
- Press “Connect” and wait for your device to connect.
How to Connect via Ethernet?
- Acquire one extra Ethernet cable.
- Connect the cable to your PC/laptop.
- Plug the other end of the cable into your network device.
- Wait for the Ethernet cable to start blinking.
Notice: Once connected, the Ethernet cable’s ports should start flickering to indicate that the connection is successful.
This means that your PC/laptop is now connected to the Xfinity router!
4. Activate your Xfinity Internet!
This is how to setup the Xfinity WiFi router. Next, we must activate the Xfinity internet by visiting the online activation page.
From there, you’ll be able to follow easy instructions to set up your Xfinity network device and benefit from all networking and WiFi features!
- Navigate to xfinity.com/activate and sign in with your user ID and password
Note: The Xfinity system should automatically detect that you have a verified network router/modem connected to your device and move you on to the software setup!
How to Setup Xfinity WiFi Router Setup On Gateway?
The gateway device includes the attributes of both a regular WiFi router and an ISP’s modem.
Thus, the gateway will connect both into the service port and then act as a router by spreading WiFi within your household.
Let’s learn how to set up one of Xfinity’s gateways!
1. Connect the Gateway to Power & Service!
The first and most important step to installing an Xfinity gateway is managing all of the important cables.
Since the cable is a standalone router and modem in one, the device will directly connect to the service outlet.
How to Install the Gateway’s Power Cord:
- Connect the A/C end of the cord to the outlet.
- Plug the other end of the adapter into your gateway.
- Turn on the modem and check if the device will work.
How to Install the Gateway’s Coaxial Cable:
- Plug the coaxial cable into the service outlet.
- Install the other end of the coax into the “Coax In” port on the gateway.
- Wait for 20-30 seconds until the gateway recognizes the connection.
Let’s move on to activating your Xfinity gateway!
2. Activate the Xfinity Gateway
Fortunately, activating an Xfinity gateway is the same as activating your Xfinity modem or router.
You must simply connect an external device to the gateway (learn how in guide #1, step #3) and then access the activation page of Xfinity.
- Once your third-party device is activated, go to xfinity.com/activate
Note: Once at the activation page, follow the instructions to set up the software of your gateway!
3. Test the Gateway’s Attributes
With Xfinity gateway devices, you must be specifically aware of the internet speeds and network attributes.
Xfinity has designed a speed test that will allow the users to verify if their gateway reaches the necessary connection speeds and work alright.
Gateway Network Attributes:
- Upload speed – how fast your gateway uploads data to the internet
- Latency – The amount of time it takes for data from your PC to travel
- Protocol – A digital mechanism, necessary for routing your data.
- Host – The server that’s handling your internet connection
How to Test Xfinity Internet Connection:
- Connect your PC/laptop to the Xfinity gateway.
- Visit speedtest.xfinity.com through your browser.
- Click on “Start Your Test” at the center of the page.
- Wait for your test results to be verified
Note: Compare the results of the test and the promised data speed by Xfinity.
If your gateway reaches the appropriate connection speeds, then your network is ready to go!
Quick Recap:
Now that we’ve learned how to setup Xfinity WiFi router, we know that this is possible by installing the network device’s power and service cable first.
The next step is to visit “xfinity.com/activate” from a connected device to complete the Xfinity activation setup.
