Steps to Hide Your SSID
- Log into your router’s configuration page (usually by entering your router’s IP address in a web browser).
- Locate the wireless settings.
- Look for the option to disable SSID broadcast.
- Save changes and restart your router.
Limit DHCP Leases
Configuring your router to limit the number of devices that can connect to your network through DHCP settings can add another layer of security. You can reserve IP addresses for your home devices and restrict new devices.
Use Strong Passwords
Always use a strong password for your WiFi network. Include a mix of letters, numbers, and special characters to create a difficult-to-guess password.
- Use at least 12 characters.
- Avoid easily guessable information, like birthdays or names.
When Should You Consider Professional Help?
If you suspect that you are a victim of unauthorized access or if securing your network is proving overly complex, it might be worth hiring a professional. IT experts can conduct a thorough assessment of your network and implement advanced security measures.
How to Detect Unauthorized Access
Most routers have a built-in interface that allows you to monitor connected devices. Here’s how to check:
