Many users fail to change the default settings on their routers and access points. These settings often include default usernames, passwords, and WiFi network names (SSIDs) that hackers can exploit.
Common Default Credentials
| Router Brand | Default Username | Default Password |
|---|---|---|
| Netgear | admin | password |
| Linksys | admin | admin |
Changing these default settings is a fundamental step in protecting your network.
3. Weak Passwords
Using a simple, easily guessable password is one of the most significant vulnerabilities. Generic passwords such as “password123” or “admin” can be cracked within seconds.
What Makes a Strong Password?
- Length: Passwords should be at least 12 to 16 characters.
- Complexity: Use a mix of uppercase, lowercase, numbers, and symbols.
- Unpredictability: Avoid easily guessed information, like birthdays or names.
Reminder: Regularly update your password and avoid using the same password across multiple platforms.
4. Lack of Network Encryption
Encryption is the foundation of securing your WiFi network. If your network employs no encryption or uses an outdated one, it’s essentially open to anyone nearby.
WiFi Encryption Standards
