Your home Wi-Fi router is the gateway to every device in your house — phones, laptops, smart TVs, security cameras. Yet most people set it up once and never touch the security settings again. Here's what to change.
1. Change the Default Admin Password
Every router ships with a default admin username and password (often admin/admin or admin/password). These are publicly listed on the internet. Log into your router (usually at 192.168.1.1 or 192.168.0.1) and change the admin password to something strong and unique.
2. Use WPA3 or WPA2 Encryption
Check your router's wireless security settings. If it's set to WEP or WPA (not WPA2), change it immediately — both are broken and can be cracked in minutes. WPA2-AES is the minimum; WPA3 is better if your router supports it.
3. Change the Default Network Name (SSID)
A network named "Telstra Gateway 7857" or "Netgear-4F82" broadcasts your router model to anyone scanning nearby. Knowing your router model helps attackers target known vulnerabilities. Name your network something that doesn't identify the hardware.
4. Update Your Router's Firmware
Router manufacturers regularly release firmware updates patching security vulnerabilities. Log into your router admin panel and check for firmware updates. Many modern routers can do this automatically — enable it if the option exists.
5. Disable Remote Management
Remote management allows access to your router's admin panel from the internet. Unless you specifically need this, disable it. Most home users have no reason to manage their router remotely.
6. Create a Guest Network for IoT Devices
Smart home devices — TVs, doorbells, smart speakers — are notorious for poor security. Putting them on a separate guest network means that if one is compromised, the attacker can't pivot to your laptop or NAS drive on the main network.
7. Use a Strong Wi-Fi Password
Your Wi-Fi password should be at least 12 characters. Anyone who connects to your Wi-Fi can potentially intercept traffic on the network. A weak Wi-Fi password is an easy entry point, especially in apartment buildings where many people are in range.
