Install your modem using QuickConnect

Please read our detailed installation instructions, which cover everything from modem placement to whether filters are required, before completing the steps below. Ensure that an Ethernet cable is being used to connect your computer to the modem and that the modem is hooked into a wall port.


After plugging it in, wait 15 minutes for the modem to install updated software. Then, open any browser on your computer and go to (not "https").

All modems welcome here!

The QuickConnect steps below will look and work the same, no matter which model of modem you have. 

1. When you go to, you will see a welcome screen like this. You can choose the English or Espanol version at the top. Then click "Next" to start the setup process. Note: Be sure to use "http" and NOT "https" when you enter the URL.

2. In most cases, your identity will be verified automatically. If the system can't do this, you will be asked for additional information.

If the automatic verification isn't successful, you will be prompted to enter the account number shown on your bill or order confirmation email from Brightspeed. Enter that number and your billing zip code, then click "Continue."

If you’d like to confirm your identify in another way, select "Rather try something else?" Choose from the list of options, then enter that information on the next screen and click "Continue."

4. Wait as the modem is configured to connect to the Brightspeed network. Do not close your browser window while this is in progress.

Quick Connect step 6

If the system is unable to configure your modem automatically, you will be guided to do this manually through the modem's online settings portal. You will see this screen, asking which modem you have. Choose the correct option and click "Next."

The next screen will give you the link and information you need to go into the modem's online settings portal and run Quick Setup:

  1. Keeping your QuickConnect window open, go ahead and open a new browser window or tab. Type "" into the address bar, then hit enter. 
  2. Log in using the Administrator Username and Password printed on the sticker label on the bottom or side of your modem. 
  3. Click on "Quick Setup" then enter the PPP username and password shown to you on the QuickConnect screen, as seen in the sample below. Click "Apply."
  4. Wait for setup to complete and for the Ethernet, DSL and Internet lights to turn green on your modem (or the single light ring to turn green, if you have a C4000 model).
  5. Go back to the QuickConnect tab in your browser and click "Next."

5. You will be given the option to turn on the modem's wireless router, so that you can connect multiple devices to your own WiFi network. Most customers will want to do this. Select "Yes, activate wireless" (or "No" if you don't want WiFi turned on; you can change this later in your modem settings if you choose.) Click "Next."

Quick Connect step 7

6. You will be shown the default wireless settings for your modem/router. They will look similar to the sample shown below. You can choose to keep the default network name (SSID) and password (security key), or to customize them. For security, we recommend changing these to something that will be easy for you to remember, but impossible for others to guess.

7. You can decide if you'd like detailed instructions on connecting your devices to your modem through WiFi. Click "Yes" or "No," then click "Next." If you chose yes, then on the next screen select which kind of device(s) you want to connect. When you are finished with this step, click "Next."

9. On this next screen, we strongly recommend you save a record of your key account information. Once you're finished, click "Next."

Quick Connect step 12

10. The basic installation is now complete, and you can get online. You can exit the installation process now, or continue on to some additional services. This will not impact your internet service. Choose "Yes" or "No," then click "Continue."


At this point, you can also check your modem's status lights to confirm that the installation is complete.

Quick Connect step 13

Check your modem's status lights to confirm installation

The front and/or back LEDs of your modem will inform you of its connection status as you complete the installation process. To get a description of the status lights on your modem, click on the appropriate area below for your model.
