| The 5 Best Apps to Check WiFi Security and Detect Hackers |
Common WiFi Security Problems and Solutions
WiFi networks have inherent vulnerabilities that can be exploited by attackers if left unprotected:
- Weak default passwords – Many routers use easy-to-guess admin passwords that hackers can look up online. Always change the default password to one that is long and complex.
- Outdated firmware – Old router firmware versions often have security flaws. Regularly check and install the latest firmware updates.
- Unencrypted networks – Data sent over open, unencrypted networks can be easily intercepted. Use WPA3 or WPA2 encryption on your wireless network.
- Too many connected devices – The more devices on your network, the more potential entry points for hackers. Limit connections and beware of unauthorized devices.
