Advanced Security Measures
Once you’ve followed the basic steps for securing your WiFi, you may want to explore more advanced tactics.
1. Use MAC Address Filtering
Each device has a unique Media Access Control (MAC) address. By enabling MAC address filtering, you can specify which devices can join your network.
Action Steps:
- Access MAC filtering options in your router settings.
- Add the MAC addresses of your trusted devices. This can usually be found in the device settings or on the device itself.
2. Limit DHCP Leases
Dynamic Host Configuration Protocol (DHCP) assigns IP addresses to devices on your network. Limiting the number of IP addresses available helps prevent unauthorized devices from connecting.
Action Steps:
- In the router settings, locate the DHCP settings.
- Set the DHCP lease limit to the number of devices you own plus a small buffer for guests.
3. Disable Remote Management
Many routers offer remote management features that allow access to your router’s settings from outside your network. While convenient, this can be a significant security risk if left unsecured.
Action Steps:
- Disable any remote management features in your router settings.
