- Limit Network Visibility: Turn off SSID broadcast if you want extra privacy—just remember to manually enter the SSID on devices when connecting.
Additional Security Features
- Port Filtering and Blocking: Some devices let you disable or restrict certain ports (e.g., FTP or HTTP) to reduce the attack surface. If you don’t need a particular port, keep it blocked.
- Firmware Updates: Check for device firmware updates periodically to patch security flaws.
- MAC Address Filtering: On select models, you can whitelist your device’s MAC addresses, preventing unknown devices from joining.
3. How to Keep Your Wi-Fi Private and Protect Sensitive Data
Many people overlook the importance of consistently monitoring and maintaining Wi-Fi privacy settings, which can lead to data leakage or unauthorized access.
To keep your Wi-Fi private, use strong passwords, enable encryption, and regularly check for suspicious connected devices or unknown software updates.
Frequently Overlooked Measures
- Change Password Periodically: Regularly update your hotspot password to lock out anyone who may have obtained old credentials.
- Disable Automatic Connections: On laptops or smartphones, turn off auto-connect for new networks and forget the network when not in use.
- Use a VPN: Routing data through a Virtual Private Network can add an extra layer of encryption, especially on public Wi-Fi or if your portable WiFi device is shared with others.
4. Addressing Common Questions About Portable WiFi Security
