Change your network name in the Comcast router settings

Your Comcast router broadcasts a WiFi network name — called the SSID — that appears when you search for networks on your phone or computer. By default, Comcast sets this to something like "xfinity-abcd1234", which tells anyone nearby that you use Comcast and broadcasts part of your router's serial number. Changing it to something only you recognize makes your network less of a target and harder to identify from the street.

You change the network name through your router's settings page, which you reach by typing your router's IP address into a web browser. For Comcast routers, this is usually 192.168.0.1 or 192.168.100.1. You log in with your Comcast username and password — the same ones you use to pay your bill — then navigate to the WiFi settings section and type in a new name.

The whole process takes about five minutes. You do not need to call Comcast or restart anything, though your devices will disconnect briefly when you save the change and will need to reconnect using the new name.

Key Takeaways

  • Open a web browser and go to 192.168.0.1 or 192.168.100.1, then log in with your Comcast account credentials to reach your router settings.
  • Look for the WiFi settings or SSID section, where you can change the network name to anything you choose — avoid using your address, last name, or other identifying information.
  • Save your changes and reconnect your devices to the network using the new name you created.
  • Changing the network name does not affect your internet speed or connection — it only changes what appears when someone searches for nearby WiFi networks.

Step-by-step: accessing your router settings

Start by opening any web browser on a device connected to your Comcast WiFi. Type 192.168.0.1 into the address bar and press Enter. If that does not load, try 192.168.100.1 instead — Comcast uses both depending on the router model.

A login page will appear asking for a username and password. Enter your Comcast account username and password — the same ones you use to manage your account online or through the Comcast app. If you have never logged in before, you may need to set up a password through the Comcast website first. Click the login button and wait for the settings page to load.

Once you are logged in, look for a menu option labeled WiFi, Wireless, or Network Settings. Different Comcast router models have slightly different layouts, but this section is always near the top of the menu. Click on it to see your current network settings.

Finding and changing the network name

In the WiFi or Wireless settings section, you will see a field labeled SSID or Network Name. This is the name that appears when you search for networks on your phone or laptop. The current name is usually something like "xfinity-2G4B" or "xfinity-5G-abcd1234" — the "xfinity" part comes from Comcast's default setup.

Click in the SSID field and delete the current name. Type a new name that you will recognize but that does not broadcast personal information. Good choices are something like "HomeNetwork" or "Workspace". Avoid using your street address, last name, or house number, since anyone nearby can see this name and might use it to target your home.

Some routers have separate fields for the 2.4 GHz and 5 GHz networks — these are two different frequency bands that your router broadcasts. You can give them the same name or different names. Most people give them the same name so their devices automatically pick the best one. If you see both fields, change them both to the same new name.

Saving your changes and reconnecting devices

After you type the new network name, look for a Save, explore, or OK button at the bottom of the page. Click it to save your changes. The router will process the change for a few seconds, and you may see a message saying the settings have been updated.

Your WiFi network will go offline briefly — usually less than a minute — while the router applies the new name. When it comes back online, the old network name will no longer appear when you search for networks. Instead, you will see your new name in the list.

On each of your devices — phone, laptop, tablet, smart TV — you will need to "forget" the old network and reconnect to the new one. On most phones, go to Settings > WiFi, find the old network name, tap it, and select "Forget". Then search for networks again, find your new network name, and enter your WiFi password to reconnect. Repeat this for each device that was connected to your old network.

What to do if you cannot access the settings page

If 192.168.0.1 and 192.168.100.1 both fail to load, your device may not be connected to the Comcast WiFi, or your router may use a different address. Check that you are actually connected to your Comcast network — look at your WiFi settings and confirm the network name appears and shows as connected.

If you are connected but the page still will not load, try restarting your router. Unplug it from power, wait 30 seconds, and plug it back in. Wait another two minutes for it to fully restart, then try the IP address again. If it still does not work, you can find your router's specific IP address by checking the sticker on the back of the device — it usually lists the address and default login information.

If you have forgotten your Comcast account password, you can reset it through the Comcast website before attempting to log into the router. You will need your account number and a phone number or email associated with your account.

Choosing a find network name

While changing the network name does not directly protect your WiFi from being hacked, it does make your network less visible and less of a target. A generic name like "HomeNetwork" tells potential attackers nothing about your router model, your internet provider, or your location. The default "xfinity-abcd1234" broadcasts all three.

Avoid network names that include your address, phone number, last name, or the word "password". Do not use a name that suggests the network is unprotected or open to guests. Keep the name straightforward and memorable so you do not forget it when reconnecting devices.

The network name itself is not encrypted — anyone nearby can see it. The real security comes from your WiFi password, which you should keep strong and change periodically. Your password is set separately in the router settings, usually in a section labeled WiFi Security or Wireless Security.

Frequently Asked Questions

Will changing the network name disconnect my internet?

No. Changing the network name only affects WiFi — the wireless signal your devices see. Your internet connection itself stays active. Your devices will disconnect from WiFi briefly while the router applies the change, but your internet service does not stop.

Do I need to restart my router after changing the network name?

No. The router automatically applies the change and restarts the WiFi broadcast within a minute. You do not need to unplug it or do anything else. Your devices will see the new network name appear in their WiFi list shortly after you save the change.

What if I forget the new network name I created?

Log back into your router settings at 192.168.0.1 or 192.168.100.1 and check the SSID field — it will show the name you set. You can also look at any device that is currently connected to the network; it will display the network name in your WiFi settings.

Can I change the network name on my phone or through the Comcast app?

No. You must change the network name through the router settings page in a web browser. The Comcast app lets you manage your account and bill, but not your WiFi settings. You need to access the router directly through 192.168.0.1 or 192.168.100.1.

What if my router has a separate guest network?

Guest networks have their own SSID field in the router settings, usually in a section labeled Guest WiFi or Guest Network. You can change the guest network name separately from your main network. This is useful if you want visitors to connect to a different network than your personal devices.
