Why Wi-Fi Security Matters

An unsecured Wi-Fi network can allow:

Neighbours using your internet (slowing it down)

Hackers intercepting your online activity

Unauthorised access to devices on your network

Legal liability if someone uses your connection for illegal activities

Step 1: Access Your Router Settings

Open a web browser

Type your router's address (usually **192.168.0.1** or **192.168.1.1**)

Enter the login credentials (check the sticker on your router for the default)

If you haven't changed the default password, **do this first**

Step 2: Change the Default Admin Password

This is different from your Wi-Fi password:

Find **Administration** or **System** settings

Change the router login password to something strong

Write it down and keep it somewhere safe

The default admin password is usually "admin" or "password" — anyone who knows this can change your settings.

Step 3: Set a Strong Wi-Fi Password

Find **Wireless** or **Wi-Fi** settings

Look for **Security** or **Encryption**

Select **WPA3** (or WPA2 if WPA3 isn't available)

Set a strong password (at least 12 characters)

Never use WEP — it can be cracked in minutes

Step 4: Change Your Network Name (SSID)

Change the default network name (like "NETGEAR-5G" or "Telstra1234")

Don't include personal information in the name

Avoid names that identify your router brand

Step 5: Enable Guest Network

If you have visitors who need Wi-Fi:

Enable the **Guest Network** feature

Set a different, simpler password

This keeps guests separate from your main network

Change the guest password periodically

Step 6: Keep Your Router Updated

Check for firmware updates in your router settings

Enable automatic updates if available

Old firmware can have security vulnerabilities

Additional Security Tips

**Disable WPS** (Wi-Fi Protected Setup) — it's a known security weakness

**Disable remote management** unless you specifically need it

**Use the 5GHz band** for devices that are close to the router (faster and less interference)

**Position your router centrally** in your home for best coverage

Optimal Router Placement

For best coverage:

Place it in a **central location**

Keep it **elevated** (on a shelf, not on the floor)

Avoid placing it near **metal objects or mirrors**

Keep it away from **microwaves and cordless phones**

Don't hide it in a **cupboard or behind furniture**
