Change Your WiFi Name and Password Through the Xfinity App or Website

You can change both your WiFi network name (called the SSID) and password through the Xfinity My Account app or the Xfinity website. The process takes about five minutes and requires you to log in with the same username and password you use to pay your Xfinity bill. After you make the change, all your devices will disconnect from the old network and you'll need to reconnect them using the new name and password.

The easiest route for most people is the mobile app, since you can do it from anywhere. If you prefer a computer, the website works the same way — the steps are nearly identical.

Key Takeaways

  • You change your WiFi name and password through the Xfinity My Account app or website, not through your router itself.
  • You need your Xfinity account username and password to log in, which is different from your WiFi password.
  • After you save a new WiFi password, every device connected to your network will disconnect and need to reconnect with the new password.
  • Changes take effect when ready, but it can take a few minutes for all devices to recognize the new network name.

Change Your WiFi Name and Password on the Xfinity App

Open the Xfinity My Account app on your phone or tablet. If you don't have it, read it from the Apple App Store or Google Play Store — it's free. Log in with your Xfinity account username and password (the one you use to pay your bill, not your WiFi password).

Once you're logged in, tap the menu icon (three horizontal lines) at the bottom right of the screen. Select Internet, then look for WiFi Settings or Manage WiFi. Tap the option that says WiFi Name (SSID) or Network Name. Type in the new name you want — it can be up to 32 characters and can include letters, numbers, and spaces. Tap Save or Confirm.

Next, go back to WiFi Settings and find the option for WiFi Password or Network Password. Tap it and enter your new password. Passwords must be at least 8 characters long and can include uppercase letters, lowercase letters, numbers, and symbols. Tap Save or Confirm. The app will show a confirmation message — your changes are now active.

Change Your WiFi Name and Password on the Xfinity Website

Go to xfinity.comcast.net in any web browser and log in with your Xfinity account username and password. Once you're logged in, look for the Internet section in the main menu or dashboard. Click WiFi Settings or Manage WiFi.

Find the field labeled WiFi Name (SSID) or Network Name and click in it. Clear the current name and type your new one — up to 32 characters, letters, numbers, and spaces allowed. Below that, find the WiFi Password or Network Password field. Clear it and enter your new password (at least 8 characters, can include uppercase, lowercase, numbers, and symbols). Click Save or explore Changes. The website will confirm the update — your new name and password are now live.

What Happens to Your Devices After You Change the Password

Every device currently connected to your WiFi will disconnect within a few seconds of the change. This includes phones, tablets, laptops, smart TVs, printers, and any other connected devices. You'll see them drop off your network one by one.

To reconnect each device, open its WiFi settings and look for your network by its new name. Select it, enter the new password you just created, and wait for it to connect. Devices usually reconnect within 30 seconds, though some smart home devices may take a minute or two. If a device won't reconnect, restart it and try again — this fixes the problem in most cases.

Choose a WiFi Name and Password That Work for You

Your WiFi name (SSID) is what other people see when they look for networks to join, so pick something you'll recognize. Avoid using personal information like your address or phone number. Many people use their last name, a street name, or something straightforward like "Home WiFi" or "Guest Network" if they set up a separate one.

Your WiFi password is what people need to type to connect, so make it something you can remember or write down in a safe place. Avoid passwords that are too straightforward (like "password123" or "12345678") because anyone nearby with basic tools can crack them. A mix of uppercase and lowercase letters, numbers, and a symbol or two is strong enough for home use — for example, "BlueSky#2024Home" or "Maple47Oak$Tree".

Troubleshoot If Your Changes Don't Appear

If you've saved a new WiFi name or password but your devices still see the old network name, wait five minutes and check again. Sometimes the change takes a few minutes to reach your router. If the old name is still showing after five minutes, log back into the Xfinity app or website and verify that your changes were actually saved — sometimes a connection glitch prevents the save from going through.

If you see the new network name but devices can't connect with the new password, double-check that you typed the password correctly when you saved it. Passwords are case-sensitive, so "BlueSky#2024" is different from "bluesky#2024". If you're not sure what you entered, go back into WiFi Settings, clear the password field, and type a new one. Make sure there are no extra spaces at the beginning or end.

If your router isn't responding at all, restart it by unplugging the power cable for 30 seconds, then plugging it back in. Wait two to three minutes for it to fully restart. Once the lights stop blinking, try changing your WiFi settings again.

Frequently Asked Questions

Is my WiFi password the same as my Xfinity account password?

No — they are completely separate. Your Xfinity account password is what you use to log into the Xfinity app or website to manage your bill and services. Your WiFi password is what guests and devices need to type to connect to your internet. You can change one without affecting the other.

Can I change my WiFi name and password from my router instead of the app?

You can access your router's settings directly by typing its IP address into a web browser (usually 192.168.0.1 or 192.168.100.1), but the Xfinity app and website are simpler and less likely to cause problems. If you do use the router settings, make sure you know what you're doing — incorrect changes can disconnect your internet entirely.

How often should I change my WiFi password?

There's no set rule, but changing it once or twice a year is reasonable for home use. Change it sooner if you suspect someone has your password, if you've given it to a guest who no longer visits, or if your network feels slow (sometimes an unauthorized user is consuming bandwidth).

What if I forget my new WiFi password?

Log back into the Xfinity app or website, go to WiFi Settings, and look at the password field — it will show your current password (usually with dots or asterisks for security). You can also reset it to a new one right there. Write it down or save it in a password manager so you don't lose it again.

Do I need to restart my router after changing the WiFi name or password?

No — the changes take effect when ready without a restart. However, if devices are having trouble reconnecting, restarting the router (unplug for 30 seconds, plug back in) often solves the problem.
