If you find any unfamiliar devices, remove them and consider changing your WiFi password immediately.
7. Limit DHCP Leases
Dynamic Host Configuration Protocol (DHCP) leases automatically assign IP addresses to devices on your network. To enhance security:
- Limit the number of available DHCP addresses to match the devices you own.
- This prevents unauthorized devices from easily connecting to your network.
8. Schedule Regular Reboots
Rebooting your router regularly can help maintain performance and security. You can set a schedule within your router settings for automatic reboots.
Advanced Security Measures
For those looking to implement more advanced security measures, consider the following options:
1. MAC Address Filtering
Media Access Control (MAC) address filtering allows you to specify which devices can connect to your network based on their unique hardware address. While it is not fully foolproof, it adds another layer of security:
- Log into your router settings and locate the MAC filtering section.
- Add the MAC addresses of devices you wish to allow while denying others.
2. Utilize a VPN (Virtual Private Network)
Using a VPN can help secure all data transmitted over your network, providing an additional layer of encryption. This is particularly useful if you connect to public WiFi networks frequently.
3. Disable WPS (WiFi Protected Setup)
WPS simplifies the connection process but can come with vulnerabilities. Disabling WPS in your router settings will reduce the risk of unauthorized access.
