Neighbour Router Access: Is Your Network Safe?

TL;DR

Yes, a neighbour could access your router if it’s not properly secured. This guide shows you how to check and fix common vulnerabilities like weak passwords and open ports.

Checking Your Router Security

1. Find Your Router’s IP Address: This is usually the gateway address. On Windows, open Command Prompt and type

   ipconfig

   . Look for ‘Default Gateway’. On macOS, open Terminal and use

   netstat -rn | grep default

   .

2. Access Your Router’s Settings: Open a web browser and enter your router’s IP address in the address bar. You’ll be prompted for a username and password. If you haven’t changed these, they are often printed on a sticker on the router itself (e.g., admin/password, admin/admin).
3. Change the Default Username and Password: This is the most important step! Choose a strong, unique password.

Securing Your Wireless Network

1. Check Your Encryption Type: Look for settings like WPA2 or WPA3. Avoid using older standards like WEP as they are easily cracked.
2. Use a Strong Wi-Fi Password (WPA2/WPA3): Make it long and complex, with a mix of letters, numbers, and symbols.
3. Hide Your SSID: This makes your network less visible to casual scanners. Note: this isn’t foolproof security but adds another layer.

Advanced Security Checks

1. Check Connected Devices: Most routers show a list of devices connected to your network. Look for any you don’t recognise.
2. Enable Firewall: Ensure the router’s built-in firewall is enabled. This blocks unwanted incoming connections.
3. Disable Remote Management (if not needed): If you don’t need to access your router settings remotely, disable this feature. It’s a potential security risk.
4. Check Port Forwarding: Only forward ports if absolutely necessary for specific applications. Unnecessary port forwarding can create vulnerabilities.

Updating Your Router

Router manufacturers regularly release firmware updates to fix security bugs. Check your router’s settings page for an update option and install them promptly.

If You Suspect a Breach

• Change all passwords: Wi-Fi password, router admin password, and any accounts accessible through the network.
• Contact your Internet Service Provider (ISP): They may be able to offer assistance or investigate further.
• Consider a factory reset: This will restore your router to its default settings. Be sure to back up any custom configurations first, if possible.
