How to Whitelist Devices on Fios Gateway
Want to lock down your Wi-Fi so only approved devices can connect? Whether you’re protecting against:
✔ Wi-Fi leechers (neighbors stealing bandwidth)
✔ Smart home hacking (unauthorized IoT access)
✔ Kid’s friends connecting without permission
This guide will show you exactly how to whitelist devices on Fios Gateway (CR1000A/G3100) using MAC address filtering, the most secure way to control network access.
We have two methods to Whitelist Devices on Fios Gateway.
Method 1: MAC Filtering via Admin Panel
Best for: Permanent, tamper-proof whitelisting
Step 1: Gather Device MAC Addresses
- Windows: Open Command Prompt → Type ipconfig /all → Find “Physical Address”
- Mac/Linux: Open Terminal → Type ifconfig → Find “ether”
- Phones/Tablets:
- Android: Settings → About Phone → Status → Wi-Fi MAC
- iPhone: Settings → General → About → Wi-Fi Address
Pro Tip: Label each MAC address (e.g., “John’s iPhone – 12:34:56:78:90:AB”)
Step 2: Enable MAC Filtering on Fios Gateway
Connect to your Fios network (wired recommended)
- Go to http://192.168.1.1 (or fiosgateway.org)
- Log in (default credentials on router sticker)
- Navigate to:
- Advanced > Security > Access Control
- Turn on “Allow Listed Devices Only”
- Add MAC Addresses of approved devices
- Save & Reboot
Important: Any non-whitelisted device will instantly lose internet access!
Method 2: Guest Network + Whitelisting
Best for: Homes with frequent guest devices, most useful for families.
- Create a Guest Network (My Verizon App → Internet → Guest Wi-Fi)
- Enable “Allow Listed Devices Only” (same as Method 1)
- Whitelist only family devices on the main network
- Give guests temporary access via the Guest Network
🔹Bonus: Set Guest Network to auto-disable after 24 hours
⚡Pro Tips for Maximum Security
✔ Hide your SSID (makes network invisible to scanners)
✔ Change Wi-Fi password monthly (if not using whitelist)
✔ Monitor connected devices in My Verizon App
Troubleshooting Whitelist Issues
❌ Problem: Whitelisted device can’t connect
✅ Fix: Double-check MAC address (iPhone/Android sometimes use randomized addresses)
❌ Problem: Can’t access admin panel after enabling
✅ Fix: Connect via Ethernet (whitelisting may block Wi-Fi access)
❌ Problem: Smart devices (like Roomba) won’t connect
✅ Fix: Temporarily disable whitelist during setup
💡 Final Recommendations
✔ Start with 2-3 trusted devices (avoid locking yourself out)
✔ Keep a backup admin PC wired (in case Wi-Fi access fails)
✔ Combine with WPA3 encryption for maximum protection
