One Modem. Wi-Fi Built Right In.

Unlike a standalone cable modem, the CGA4234 has Wi-Fi built in. For most homes, that means you don’t need a separate Wi-Fi router to get connected.

Your CGA4234 provides both 2.4 GHz and 5 GHz Wi-Fi networks, allowing you to choose the best connection for different devices around your home.

Your default Wi-Fi network names and password are printed on the modem’s label, so keep that information handy during setup.

2.4 GHz or 5 GHz — Which Should I Use?

2.4 GHz — Better Range

2.4 GHz is designed to travel farther and generally performs better through walls and over longer distances.

It can be a great choice for:

• Security cameras
• Video doorbells
• Smart-home devices
• Devices located farther away from your CGA4234

If a camera, doorbell or smart-home device is having trouble connecting, try the 2.4 GHz network.

5 GHz — Better Performance

5 GHz generally provides higher wireless speeds but has a shorter effective range than 2.4 GHz.

It’s ideal for higher-bandwidth devices such as:

• Streaming devices
• Smart TVs
• Gaming consoles
• Computers
• Phones and tablets

Important — First-Time Setup Required

Setting up your CGA4234 for the first time? Before your Internet connection will function normally, you may need to complete the modem’s initial Wi-Fi setup.

First, connect your laptop, phone or tablet to the CGA4234 using either the default 2.4 GHz or 5 GHz Wi-Fi network printed on the modem’s label.

Look for the SSID (Wi-Fi Name) and Pre-Shared Key (Wi-Fi Password) printed on the bottom of the unit.

Once connected to the default Wi-Fi network, open a web browser and visit the following first-time setup address:

Important: For first-time setup, use the complete http://192.168.0.1/index.html#/captive_portal address. Simply entering the modem’s normal management IP may not open the setup page on all phones, tablets or computers.

The CGA4234 will walk you through its first-time setup.

After completing the setup, allow approximately 2–3 minutes for the CGA4234 to apply its configuration.

Your Internet connection may not function until this first-time setup has been completed. If you’re connected to Wi-Fi but websites aren’t loading, visit 192.168.100.1 and make sure this step has been completed.

Quick Setup — Let’s Get Online

1 — Connect the Coaxial Cable

Connect the coaxial cable from your wall outlet to the coaxial connection on the modem. Make sure the connection is snug.

2 — Connect the Power

Connect the included power adapter and allow the modem to begin starting up.

3 — Give It Some Time

Wait approximately 5–10 minutes for the modem to establish its connection. During its first startup, the CGA4234 may also download configuration or firmware updates and may restart.

4 — Connect to the Default Wi-Fi

Using your laptop, phone or tablet, connect to either the default 2.4 GHz or 5 GHz Wi-Fi network using the Wi-Fi information printed on the CGA4234’s label.

5 — Complete First-Time Setup

Once connected to the CGA4234’s Wi-Fi, open a web browser and visit:

Follow the on-screen setup. When asked whether you would like to change the default Wi-Fi settings, we recommend selecting NO.

Allow another 2–3 minutes for your settings to take effect.

Once this process is complete, your CGA4234 should be ready and your Wakey Internet connection can come fully online. For future modem management, use 192.168.100.1.

Which Address Should I Use?

Setting up the CGA4234 for the first time?

Use the complete address above to open the CGA4234’s first-time setup / captive portal.

Already completed setup?

Use 192.168.100.1 to access the CGA4234 management interface after the initial setup has been completed.

Where Do I Find My Wi-Fi Information?

Your default Wi-Fi network name (SSID) and password (Pre-Shared Key) are unique to your modem.

Look for the Wi-Fi information printed on the label attached to the bottom of your CGA4234.

Helpful Tip: Take a picture of the label with your phone. If you ever need to reconnect after a reset, you’ll have the original Wi-Fi information handy without needing to move the modem.

First — Check Your Modem Lights

Check the DS, US and Internet/Online indicator on the front of your CGA4234.

If these indicators are solid, your modem has generally established a connection with the cable network.

If the DS light continues flashing, the coaxial outlet you’re connected to may not be active.

Try another coaxial outlet in your home if one is available. Common locations include:

• Living room
• Office
• Bedroom
• Basement
• Utility room

Seeing “No Internet Connection Detected”?

If you’ve just completed the setup process, your CGA4234 may still be applying its configuration.

Wait approximately 2–3 minutes and try browsing again.

If you’re still unable to access the Internet, try a simple power cycle:

1. Unplug the CGA4234 from power.
2. Wait approximately 15–30 seconds.
3. Plug it back in.
4. Allow several minutes for the modem to reconnect.

Once the modem lights have returned to normal, reconnect your device and try browsing again.

Router Mode — Default

While connected to your modem, open a web browser and enter:

Default Username: Leave blank

Default Password: Leave blank

There’s no need to worry about the blank credentials — the local management interface is only available to devices connected to your CGA4234’s local network.

Bridge Mode

If your modem has already been placed into Bridge Mode, its management interface is available at:

Default Username: Leave blank

Default Password: Leave blank

Internet Works, but 192.168.100.1 Won’t Open?

Sometimes the CGA4234’s local management page may temporarily become inaccessible even though your Internet connection is working normally.

First, wait approximately 5–10 minutes and try again.

If it still won’t open:

1. Make sure your device is connected directly to the CGA4234 by Wi-Fi or Ethernet.
2. Power-cycle the CGA4234.
3. Allow the modem to fully reconnect.
4. Confirm your Internet connection is working.
5. Visit 192.168.100.1 again.

The management page should normally become accessible again once the CGA4234 has fully restarted.

Customize Your Wi-Fi

1 — Open the Modem Interface

Open a web browser and visit:

Leave both the Username and Password blank.

2 — Change Your Wi-Fi Name

Select Wireless, followed by Radio.

Enter your desired Wi-Fi name under:

• 2.4 GHz Wireless Network
• 5 GHz Wireless Network

Click Save.

3 — Change Your Wi-Fi Password

Select Security.

Enter your desired Wi-Fi password for both the 2.4 GHz and 5 GHz networks.

Click Save to apply your changes.

Changed Your Wi-Fi Information?

Your devices may disconnect after you click Save. That’s normal.

Simply reconnect your phones, computers, TVs and other devices using the new Wi-Fi name and password you created.

For the Most Accurate Speed Test — Go Wired

For the best possible performance and the most accurate speed test, connect a computer directly to the CGA4234 using an Ethernet cable.

A wired Ethernet connection removes most Wi-Fi-related variables, including:

• Distance from the modem
• Walls and building materials
• Wireless interference
• 2.4 GHz vs. 5 GHz differences
• Your device’s Wi-Fi capabilities
• Other wireless devices competing for airtime

Once connected by Ethernet, we recommend testing with:

Don’t be surprised if your wired speed test is substantially faster than a test performed over Wi-Fi. Wireless speeds will always vary.

How Much Speed Do You Actually Need?

Many everyday Internet activities use surprisingly little bandwidth.

For example, an HD video stream may use around 5 Mbps, depending on the streaming provider and video quality.

That means a Wi-Fi speed test doesn’t necessarily need to show the full speed of your Internet plan for streaming, browsing, video calling and other everyday activities to work great.

Enable Bridge Mode

1 — Disconnect Ethernet Devices

Disconnect any Ethernet devices currently connected to the modem.

2 — Connect Your Router

Connect your own router to LAN Port 1 on the CGA4234.

3 — Open the Modem Interface

4 — Change the Working Mode

Navigate to:

Change Working Mode to:

Bridged Only

Click Save.

What Happens in Bridge Mode?

Once Bridge Mode is enabled, your own router will manage your home network and Wi-Fi.

The CGA4234 will primarily operate as the cable modem providing the Internet connection to your router.

Give Your CGA4234 a Fresh Start

A factory reset returns the modem to its original, out-of-the-box configuration and can often resolve unexpected behaviour.

1 — Keep the Modem Powered On

Make sure your CGA4234 is connected to power and turned on.

2 — Locate the RESET Hole

On the back of the CGA4234, locate the small recessed hole labelled RESET.

You’ll need a paper clip, pin or similar small object to press the reset button inside.

3 — Press & Hold for 15–25 Seconds

Carefully insert the paper clip or pin into the RESET hole and press and hold the button for approximately 15–25 seconds.

Release the button when the modem lights begin flashing or the unit begins restarting.

4 — Let the Modem Fully Restart

Allow approximately 10–15 minutes for the CGA4234 to reset, restart, obtain its configuration, check for firmware updates and reconnect to the network. The modem may restart more than once during this process.

After the Factory Reset

Once the reset is complete, the CGA4234’s original factory settings will be reinstated.

This includes the default:

• 2.4 GHz Wi-Fi network name (SSID)
• 5 GHz Wi-Fi network name (SSID)
• Wi-Fi password / Pre-Shared Key
• Router and network settings

Your original Wi-Fi information can be found on the label attached to the CGA4234.

If your phone, tablet or computer remembers your previous Wi-Fi settings, you may need to Forget This Network before reconnecting.

Apple / iPhone / iPad:
Settings → Wi-Fi → Select the network → Forget This Network

Other phones, tablets and computers provide a similar Forget Network option within their Wi-Fi settings.

Once forgotten, reconnect using the default Wi-Fi Name (SSID) and Pre-Shared Key printed on the CGA4234 label.

Because a factory reset returns the CGA4234 to its initial state, open your browser and visit the first-time setup page:

Complete the first-time setup again. When asked whether you would like to change the default Wi-Fi settings, we recommend selecting NO.

Remember: A Factory Reset Erases Your Changes

Any customized settings — including a Wi-Fi name or password you previously created, Bridge Mode and other network settings — will be erased.

After the reset, use the default Wi-Fi name and password printed on the modem’s label to reconnect.
