Are you experiencing unusually slow internet speeds, even when you’re the only one online? Your neighbors might be piggybacking on your Wi-Fi, using your bandwidth without your consent. This unauthorized access not only affects your connection speed but can also lead to serious security risks if your IP is used for illegal activities.
Fortunately, there are several steps you can take to block neighbors from using your Wi-Fi without them knowing, maintaining your network privacy without confrontation.
By following these practices, you can effectively protect your Wi-Fi from unwanted access without broadcasting your actions to those trying to access it.
1. Check Who’s Connected to Your Wi-Fi
Your first step toward securing your Wi-Fi network is identifying who’s currently using it. This will help you determine if any unauthorized devices are connected and taking advantage of your internet connection.
How to view connected devices via router settings
Accessing your router’s settings is a simple way to check for connected devices:
1. Log In to Your Router: Open a web browser, type your router’s IP address (commonly found on the router itself or in the manual), and press Enter.
2. Enter Credentials: Use the admin username and password. Often, the default is ‘admin’ for both fields unless you’ve personalized these credentials.
3. Locate the Device List: Navigate to a section labeled Device List, Attached Devices, or something similar. This page will display all connected devices.
4. Identify Connected Devices: Check the list. If there are more devices connected than you own, this suggests unauthorized access.
Using Network Monitoring Apps
Another effective method is using network monitoring apps:
- Download and Install: Apps like Datadog, Zabbix, and SolarWinds offer user-friendly interfaces to track connected devices.
- Monitor Connections: Once installed, these apps provide real-time alerts for new device connections, helping you spot unauthorized access immediately.
- Analyzing Activity: You can also review network activity through the apps, offering deeper insights into which devices might be misusing your network.
2. Change Your Wi-Fi Password Immediately
Changing your Wi-Fi password is crucial in preventing neighbors or unauthorized users from accessing your network. A strong password should be tough to guess, incorporating a mix of characters, numbers, and symbols.

Steps to update your password in router settings
1. Access Router Settings: Like before, enter your router’s IP address into a web browser, and log in using your admin credentials.
2. Navigate to Wireless Security Settings: Look for a section titled Wireless Settings, Wireless Security, or something equivalent.
3. Select Change Password: Find the option to update your Wi-Fi password.
4. Create a New Password: Ensure it’s strong by including uppercase letters, lowercase letters, numbers, and symbols. Avoid using easily guessed information such as birthdays or common words.
5. Apply Changes: Don’t forget to save your new password and apply the changes.
6. Reconnect Devices: With the new password set, reconnect all your devices to your Wi-Fi network.
By regularly changing and securing your Wi-Fi password, you can significantly reduce the risk of unauthorized connections by neighbors or other external parties.
3. Enable MAC Address Filtering
MAC Address Filtering is another effective way to secure your Wi-Fi network against unauthorized users. By enabling this feature, you can control which devices are allowed to connect to your network. Each device has a unique MAC (Media Access Control) address that can be used to identify it.
How to find and allow only trusted device MAC addresses
1. Access your router’s settings: Begin by typing your router’s IP address into a web browser and logging in with your credentials. If you’ve never changed your login details, the default username and password combination is often ‘admin/admin’.
2. Locate connected devices: Navigate to the section detailing connected devices. This could be labeled as “Device List” or “Attached Devices.” Here, you’ll find a list of all devices currently using your network and their MAC addresses.
3. Identify trusted devices: Go through the list and pick out known devices by their MAC addresses. Note the addresses of these devices as you’ll need to add them to your trusted list.
4. Set up MAC Address Filtering: In your router’s setting menu, find the option for MAC Address Filtering, often located under the wireless settings section. Enter the MAC addresses of your trusted devices to compile an exclusive list that can access your network.
5. Apply the changes: Ensure you save and apply these settings. Now, your network allows only those devices with matching MAC addresses; others will be blocked automatically, helping prevent unauthorized access.
4. Hide Your Wi-Fi Network (SSID)
Hiding your Wi-Fi network’s SSID (Service Set Identifier) can be an excellent layer of security. When you disable the SSID broadcast, your network essentially becomes invisible to those scanning for networks in the area.
How To Disable WIFI SSID broadcast to make your network invisible
- Access your router’s admin page: Similar to accessing for MAC Address Filtering, log into your router using your web browser.
- Navigate to wireless settings: Once logged in, locate the wireless or Wi-Fi settings section. This is where you’ll find the option to modify SSID settings.
- Disable SSID broadcast: Look for the option labeled something like “SSID Broadcast,” “Visibility Status,” or “Broadcast SSID.” Uncheck this option, or select ‘Disable’, to stop broadcasting your network’s name.
- Apply and save changes: After making these adjustments, ensure you save and apply them. By doing this, your network will no longer appear in the list of available networks on devices scanning for Wi-Fi.
Disabling SSID broadcast doesn’t make your network completely secure as savvy users might still find it, but it adds an extra layer of difficulty for casual snoopers. Pair this with a strong password and MAC Address Filtering for better defense against unauthorized access, effectively safeguarding your network without your neighbors even realizing.
5. Limit Wi-Fi Range or Use a Guest Network
To keep neighbors from using your Wi-Fi, try controlling your wireless signal’s reach. You can do this by positioning your router carefully or adjusting its signal strength, so your Wi-Fi only covers the areas you need and doesn’t extend too far.
- Router Placement: Place your router in the center of your home. This helps keep the signal from reaching outside areas unnecessarily. Avoid putting it near windows or exterior walls, as signals can leak outside.
- Signal Strength Adjustment: Many modern routers let you adjust their power settings. By lowering the output power through the router’s settings, you can reduce its range, which is useful in crowded areas where you want to keep your Wi-Fi footprint small.
You can also set up a guest network for temporary Wi-Fi sharing. This keeps guest users separate from your main network, protecting your devices and data. Guest networks can have time limits and access restrictions for extra security.
Conclusion
It’s important to keep your Wi-Fi secure to protect your privacy and internet connection. You can do this by setting strong passwords, using WPA2 or WPA3 encryption, and updating your router’s firmware regularly.
To keep neighbors from using your Wi-Fi without permission, think about hiding your network name (SSID), using a VPN like Surfshark, and keeping an eye on your network for unknown devices.
These steps will help keep your internet safe and fast. Staying alert and taking action are key to protecting your home network.
