Key Takeaways

  • Change Defaults: "admin/admin" is the first thing hackers try.
  • Encryption: Use WPA3 or WPA2 (AES). Avoid WEP/WPA (TKIP).
  • Disable WPS: It is a major security vulnerability. turn it off.
  • Guest Network: Isolate smart devices (IoT) from your PCs.

A weak Wi-Fi password is an open door to your digital life. Here are 5 steps to lock down your home network.

1. Change Default Login Credentials

Routers come with default logins like "admin/admin". Hackers have lists of these. Log into your router (usually at 192.168.1.1 or 192.168.0.1) and change the admin password immediately.

2. Use WPA3 or WPA2 (AES)

Go to Wireless Settings. Ensure your encryption mode is set to WPA3-Personal. If your devices are older, WPA2-Personal (AES) is the second best choice. Never use WEP—it can be cracked in minutes by a teenager.

3. Disable WPS (Wi-Fi Protected Setup)

WPS is that convenient button to connect without a password. It is also massively insecure and easily brute-forced. Turn it off in your router settings to prevent unauthorized access.

4. Rename your SSID

Don't use "Linksys" or "Netgear". Default names tell hackers exactly what router model you have and what vulnerabilities to try. Use a generic name like "SkyNet" or "FBI Surveillance Van #4".

Pro Tip: Guest Network

Enable a Guest Network for your friends and your IoT devices (TVs, Fridges). This keeps them isolated from your main computers where your banking data lives. If the fridge gets hacked, your PC is safe.

Frequently Asked Questions (FAQ)

Should I hide my Wi-Fi name (SSID)?
It doesn't really help. Hackers can still see "Hidden Networks" with scanner tools. It causes more connection problems for you than security benefits. Better to just use WPA3.
How often should I change my password?
Every 6-12 months, or immediately if you suspect unauthorized access (e.g., internet is slow).
