Sharing Wi-Fi is convenient, but sometimes unwanted devices sneak into your network. This can slow things down, expose personal data, or even create security risks. Knowing how to block strangers from your Wi-Fi helps keep your internet fast and safe, while ensuring only trusted users stay connected. Here are simple steps you can take to protect your network.
1. Log in to Your Router
Start by accessing your router’s settings through a web browser. Type in the router’s IP address (usually found on the device itself or in the manual, often something like 192.168.1.1). Use your login details—many routers default to “admin” for both username and password unless you’ve changed them. Once inside, you’ll find options to manage who’s connected.
2. Check Connected Devices
Look for a section called “Connected Devices” or “Device List.” This shows every phone, laptop, or smart gadget using your Wi-Fi. Match the names or MAC addresses with your own devices. Anything unfamiliar could be an intruder.
3. Block Suspicious Devices
Most routers let you remove unwanted users directly. Next to the suspicious device, look for “Block,” “Blacklist,” or “Deny Access.” Once selected, that device won’t be able to connect again—even if it knows your password. Some routers also allow MAC address filtering, giving you tighter control over which devices can join.
4. Change Your Wi-Fi Password
If you see several unknown users, the quickest fix is to reset your Wi-Fi password. In your router’s Wireless or Security settings, create a strong password with a mix of letters, numbers, and symbols. Save the changes, then reconnect your trusted devices. This automatically kicks off anyone still using the old password.
5. Use Strong Encryption
Always make sure your network is secured with WPA2 or WPA3 encryption. Avoid outdated options like WEP, which are easy to hack. Strong encryption ensures that even if someone tries to get in, they won’t succeed without the right password.
6. Hide Your Network Name
Another option is to stop broadcasting your Wi-Fi name (SSID). In your settings, switch off SSID Broadcast. This hides your network from the list of available Wi-Fi connections. Only people who already know your exact network name and password will be able to connect.
7. Set Up a Guest Network
If friends or visitors often ask for your Wi-Fi, create a separate guest network. This lets them browse the internet without accessing your personal files or main devices. You can even set speed limits or change the guest password anytime, keeping your primary network secure.
8. Keep an Eye on Your Network
Make it a habit to check your router’s connected devices regularly. Many modern routers even come with mobile apps to track this in real time. If you notice unknown users showing up repeatedly, it may be time to upgrade your router or ask your internet provider for stronger security tools.
