Your Wi-Fi network is the gateway to everything you do online. If it’s not secure, attackers can spy on your traffic, steal personal data, install malware, or even control your smart devices.
Step 1: Change Default Router Settings
Most routers come with:
- Default admin username and password
- A generic Wi-Fi name (SSID)
- Weak encryption or outdated protocols
🔧 To change these:
Wi-Fi password
Connect to your Wi-Fi
Open a browser and enter the IP (usually 192.168.0.1 or 192.168.1.1)
Log in with default credentials (printed on router)
Update:
Router admin password
Wi-Fi name (SSID)
Step 2: Use Strong Wi-Fi Encryption
Under Wireless Settings, choose:
- ✅ WPA2 or WPA3 (if available)
- ❌ Avoid WEP or WPA1 – they are easily hacked
Set a long, random password with symbols, numbers, and uppercase letters.
📌 Example: w!Fi_4Home-8826
Step 3: Disable WPS and Remote Access
WPS (Wi-Fi Protected Setup) makes connecting easier — but also easier to hack.
🛑 Disable:
- WPS (Push-button pairing)
- Remote Administration / Web Access from WAN (unless absolutely needed)
This blocks attackers from accessing your router from outside your network.
Step 4: Enable Router Firewall & Disable Unused Features
Go to Security / Advanced Settings and:
- ✅ Enable the router’s built-in firewall
- ✅ Disable UPnP (Universal Plug and Play) — often abused by malware
- ✅ Turn off Telnet / SSH / FTP access unless you use them
🧱 This helps contain intrusions and stops devices from auto-opening ports.
Step 5: Update Your Router Firmware
Router makers release firmware updates to patch vulnerabilities.
- Check for updates in the Settings → Administration panel
- Enable automatic updates, if available
- If manual, download from the manufacturer’s website (e.g., Netgear, TP-Link)
🚨 Outdated firmware = exposed security holes.
Step 6: Use a Guest Network for Smart Devices and Visitors
Create a separate network for:
- IoT devices (smart TVs, thermostats, cameras)
- Visitors or family members
Benefits:
- Segregates traffic
- Prevents malware on one device from affecting others
- Keeps your main network clean and fast
✅ Name it something generic, like Guest-Home-WiFi
Step 7: Monitor Devices on Your Network
Use your router dashboard or tools like:
- Fing (mobile app)
- GlassWire (Windows)
- OpenWrt / DD-WRT (custom router firmware)
🔍 Look for unfamiliar devices and block or disconnect them.
Advanced Option: Use a Privacy-Friendly DNS
Instead of your ISP’s default:
- Use Cloudflare (1.1.1.1), NextDNS, or Quad9
- Change this in your router’s DNS settings
Benefits:
- Faster, encrypted DNS resolution
- No logging or resale of your browsing data
🌐 1.1.1.1 – Privacy-first DNS by Cloudflare
