Where to change your Comcast Business WiFi password
You change your Comcast Business WiFi password through the Xfinity My Account app or website, not through your router itself. Log in with the same username and password you use to pay your Comcast Business bill. Once you're in, go to the Internet section, select your gateway or modem, and look for WiFi settings or WiFi password. The exact menu path varies slightly depending on whether you're using the app or the website, but both routes lead to the same place.
If you don't remember your Comcast Business account password, you'll need to reset it before you can change your WiFi password. Use the "Forgot username or password" link on the Xfinity login page, and Comcast will send you a reset link to the email address on file. This step takes a few minutes but is necessary — you cannot change WiFi settings without account access.
Key Takeaways
- Log into your Comcast Business account through the Xfinity My Account app or website using your billing username and password.
- Navigate to Internet settings, select your gateway or modem, and find the WiFi password option to create a new one.
- Your new password takes effect when ready on all devices, but connected devices will need to reconnect using the new password.
- If you forget your new WiFi password, you can view it again by logging back into your Xfinity account at any time.
- Changing your password does not affect your internet speed, billing, or any other service — it only changes who can connect to your network.
Step-by-step: changing your password on the Xfinity website
Go to xfinity.com and click "Sign In" at the top right. Enter your Comcast Business username and password. Once you're logged in, look for "Internet" in the main menu or under "Services." Click on it, then select "Manage Internet" or "WiFi Settings."
Find your gateway or modem in the list — it will usually show the model number and your network name (SSID). Click on it, then look for "WiFi Password" or "Change WiFi Password." Enter your new password. Comcast requires passwords to be at least 8 characters long and recommends mixing uppercase letters, lowercase letters, numbers, and symbols. Once you've entered your new password, click "Save" or "Confirm." The change takes effect when ready.
Step-by-step: changing your password on the Xfinity app
Open the Xfinity My Account app on your phone or tablet and sign in with your Comcast Business credentials. Tap the menu icon (three horizontal lines) at the bottom right, then tap "Internet." Look for "Manage WiFi" or "WiFi Settings."
Select your gateway or modem from the list. Tap "WiFi Password" or "Change WiFi Password," enter your new password, and tap "Save." The app will confirm the change. Like the website, the new password takes effect right away, and all your connected devices will need to reconnect using the new one.
What happens to your devices after you change the password
When you change your WiFi password, any device currently connected to your network will stay connected until you restart it or it loses signal. The next time that device tries to connect — or the next time you restart it — it will ask you to enter the new password. You'll need to go to each device's WiFi settings, select your network name, and type in the new password.
Devices that are not currently connected will not be able to join your network until you give them the new password. This includes phones, laptops, tablets, smart TVs, printers, and any other device that uses your WiFi. If you have many devices, changing your password during a time when fewer people are using the network can make the transition smoother.
If you forget your new WiFi password
You can view your current WiFi password at any time by logging back into your Xfinity account and going to Internet settings. The password will be displayed in plain text, so you can read it and enter it on any device that needs it. You do not need to call Comcast or wait for support — the password is always visible in your account.
If you want to change it again because you're concerned someone wrote it down or you want a stronger password, you can repeat the same steps as many times as you need. There is no limit to how often you can change your WiFi password.
Why you might want to change your password regularly
Changing your WiFi password is a straightforward way to control who has access to your business network. If a former employee, contractor, or visitor once had your password, changing it removes their access. If you suspect someone is using your WiFi without permission — for example, if your internet speed has slowed or your bill has increased — a password change will disconnect them.
For a business, a strong WiFi password (one with uppercase and lowercase letters, numbers, and symbols) is harder to guess than a straightforward one. Comcast does not require a strong password, but using one reduces the risk that someone nearby could guess it by trial and error. You can change your password to something stronger whenever you want.
Troubleshooting: password change not working
If you change your password in your Xfinity account but your devices still connect with the old password, wait a few minutes — sometimes the change takes a moment to reach your gateway. If it still doesn't work after five minutes, restart your gateway by unplugging it for 30 seconds, plugging it back in, and waiting for all the lights to return to normal. Then try connecting a device with the new password.
If you're still unable to change your password or connect with the new one, check that you're logged into the correct Xfinity account — Comcast Business accounts are separate from personal Xfinity accounts, and you must use your business login. If you're certain you're in the right account and the problem persists, contact Comcast Business support at 1-866-405-5000 or through your account dashboard.

How long does it take for the new password to work on all my devices?
