Why this matters
Your Wi-Fi network connects every device in your office or home. An unsecured router can let strangers use your connection, watch traffic or reach shared files and printers. A few router settings make it much harder for anyone to get in.
What you'll need
- Access to your router (usually a label on the device)
- A computer connected to the network
Step-by-step instructions
Step 1
Log in to your router's admin page
Open a browser and enter the router address printed on its label, often 192.168.0.1 or 192.168.1.1. Some providers use an app instead.
Step 2
Change the default admin password
Replace the factory admin password with a long, unique passphrase. This is different from your Wi-Fi password.
Step 3
Use WPA3 or WPA2 (AES) encryption
In the wireless security settings, choose WPA3 if all your devices support it, otherwise WPA2/WPA3 mixed or WPA2-AES. Never use WEP or an open network.
Step 4
Set a strong Wi-Fi password
Use a passphrase of at least 14 characters. Change it if it has been shared widely or with former staff.
Step 5
Create a guest network
Put visitors and smart devices such as TVs and cameras on a separate guest network so they cannot reach business computers.
Step 6
Turn off WPS and remote management
Disable Wi-Fi Protected Setup (WPS) and remote administration unless your IT provider needs it.
Step 7
Update the router firmware
Look for "Firmware update" or "Software update" in the router settings and turn on automatic updates if available. Replace routers that no longer receive updates.
Summary
Strong encryption, a unique admin password, a guest network and current firmware keep your Wi-Fi safe from casual and targeted attacks.
