3. Wait for the Power, US/DS, and Online lights to stop flashing and go solid for one full minute.
   
   When you first plug in your Gateway, it can take up to twenty minutes for it to automatically sync, update, and reboot multiple times with your Comcast service.
   Do not unplug or turn off your Gateway during this time.

Devices can be connected to a network in two ways: wired or wireless. In order to continue, we need to determine the type of connection your device has.

A wired connection is provided by an Ethernet cable. Most commonly, these are used by desktop computers and other equipment you don't move around often.

If your device is not connected to the router with a cable, then you are using a wireless connection.

1. Connect one end of the Ethernet cable to your Gateway.
2. Connect the other end of the Ethernet cable to your computer.
   
3. After a few moments, your computer will recognize the connection.

1. Open your preferred web browser.
   • On your computer look for one of these icons.
     
   • On your smartphone or tablet, look for one of these icons.
     
2. In the address bar at the top, type xfinity.com/activate, then press enter or return.
   
3. Follow the instructions on screen to finish activating your Comcast account, and setting up a custom Wi-Fi network name.

• Wireless Network Key (Password)

Finding Network Credentials

Most wireless routers or gateways have a label with the default credentials. If the credentials aren't there, check the documentation that came with your device.

If your Internet Service Provider (ISP) installed the wireless router or gateway, they might have left you a setup sheet which may have the credentials.

To continue, we need to know what Operating System your computer is using.

There are 2 main Operating Systems for personal computers currently available, Microsoft Windows and Apple macOS.

Microsoft Windows	Apple macOS
Microsoft Windows runs on computers produced by multiple companies, such as Lenovo, Asus, Dell, Toshiba, Hewlett Packard, Acer, and Sony.	Apple is the only company that makes macOS computers.

2. Click the network you wish to connect to.
   
3. Choose if you wish to automatically connect to your network, and then click on Connect.

   It is recommended to allow your PC to be discovered on private home networks because that allows you to see other wireless devices on the Network. If you're at a public location it is suggested to select "No".

6. You can verify your connection by checking to see if it now says "Connected" next to the network.
   

1. Click the Wi-Fi icon in the menu bar. By default it will be in the upper right corner near the time and date.
    
2. If Wi-Fi is off, choose Turn Wi-Fi on.

4. Select the Wireless Network Name (SSID) of the network you want to connect to.
   
   
   
5. Networks that have a lock icon next to their name require a password. After you select your network, enter the network password when you're prompted. If you don't know the network password, check with the owner of the Wi-Fi network you're trying to join.
