To enable MAC address filtering, first log in to your router’s configuration interface following the steps given in your router’s manual (usually you just need to open your web browser and enter 192.168.0.1 into the address bar, then press [Enter]), then look for the MAC address filtering option on the Security or Advanced configurations page. Consult your router’s documentation if you have trouble finding this. You can set the MAC addresses of the PCs allowed to connect to the network on this page.
To check the MAC address of each of your PCs, follow these steps:
- Press [Windows Key] + [R], type CMD and click OK.
- At the command prompt type IPCONFIG /all and press [Enter].
- Look for the Physical Address line – this is the MAC address for your PC.
Make sure you add the MAC address of every PC you want to connect to your network. With this added level of security, even if a hacker manages to obtain your network key they will still not be able to connect to your network.
