It’s easy with Safe Surfer to install an effective porn blocker on a Spark HG531s V1 modem. Along with protecting your privacy, we also use our own behind-the-scenes technology to block porn and other harmful online content. This guide will efficiently walk you through how to install protection.

Step 1: Install DNS

Enter the address 192.168.1.254 into the top search bar of a web browser (such as Google Chrome or Firefox)

 

 

Type admin into the username box, and admin into the password box. Click the Login button.

 

 

Click the Basic menu found on the left-hand sidebar, then click the LAN submenu. The following settings are changed under the DHCP Server section.

  1. For “Primary DNS server address”, type 104.197.28.121 into the text box.
  2. For “Secondary DNS server address”, type 104.155.237.225 into the text box.

Click the Submit button.

 

 

Once the changes have been saved, click the DHCPv6 Server tab. Untick the checkbox found next to “DHCPv6 server switch”, then click the Submit button.

 

 

Once the changes have been saved, click the SLAAC tab. Untick the checkbox found next to “SLAAC switch”, then click the Submit button. Once the changes have been made, click the Logout button found at the upper-right corner.

 

 

Restart the devices connected to the modem.

Verify the protection installation by visiting ExampleAdultSite.com inside a web browser. This is a safe website designated for testing if pornographic websites are being blocked. This site should be blocked.

 

 

Step 2: Sync IP (optional)

The Safe Surfer dashboard has a feature where you can create custom block rules for your Spark modem.

Pro tip: this feature requires a Pro Surfer subscription and works best when you have a “static IP” (that is, a non-changing public IP address) with your Internet service provider. If you would like to use the sync IP feature rather than getting a Wi-Fi Lifeguard router, contact your ISP regarding how to get a static IP.

Open the Devices menu (found on the left-hand sidebar) on the Safe Surfer dashboard. Click the “+ New Device” button.

 

 

Click Wi-Fi & network > Use my existing router. Enter a name, then click the Accept button.

 

 

Go back to the Devices menu and click the Connect button found under the device listing just made.

 

 

Click the “Plain DNS” field, then click the “Link IP” button. This will sync any custom block settings.

 

 

You can now open the Blocking menu, select the router device from the blue bubble, and block categories. Click the Save button once you’re done. These changes might take a minute to sync over.

 

 

Protection complete

Great work! The devices connected to this home router should now be protected. Visit our easy-to-use online dashboard to start monitoring traffic and blocking content from our premium categories with an affordable Pro Surfer subscription.
