Dealing with neighbors who use your WiFi without permission can be a sensitive situation. You can address the issue without being rude by taking these steps:
Secure your WiFi network: Make sure your WiFi network is password-protected with a strong and unique password. Use WPA2 or WPA3 encryption, which provides better security than older encryption methods.
Change your WiFi password: If your neighbor is already using your WiFi, change the password immediately. This will prevent further unauthorized access.
Enable MAC address filtering: Most routers have a feature called MAC address filtering. You can use this to specify which devices are allowed to connect to your WiFi network based on their unique MAC addresses. Add the MAC addresses of your devices to the allowed list and block all other unknown devices.
Rename your WiFi network: Give your WiFi network a unique name that doesn't include your address or personal information. A generic name might discourage your neighbor from trying to connect.
Talk to your neighbor politely: If you have a friendly relationship with your neighbor, consider discussing the issue calmly and politely. Let them know that you've noticed someone else using your WiFi and that you've taken steps to secure it. It's possible that they might not even be aware that they were connecting to your network.
Share guest WiFi access (if applicable): If your router allows for guest network creation, consider setting up a separate guest network with limited bandwidth for visitors. This way, you can provide access to guests without giving them access to your primary network.
Monitor your network: Keep an eye on your router's connected devices list to check for any unauthorized devices. If you notice any unfamiliar devices, take appropriate actions like changing your password or enabling MAC address filtering.
Seek technical support: If you're not sure how to secure your WiFi network properly, contact your Internet Service Provider (ISP) or the manufacturer of your router for assistance.
Remember, it's essential to approach the situation with a friendly demeanor, as being rude or confrontational may lead to strained relations with your neighbor. Taking proactive steps to secure your WiFi network should prevent any further unauthorized access and help maintain a good relationship with your neighbor.
