How to setup MAC filtering in Dlink router

Media Access Control Address aka MAC Address plays a vital role to connect to the internet. To use internet, you must have network card and every network card has one unique MAC Address. If you have any MAC Address related issue, you may fail to use internet.

If you are using Wi-Fi router to use internet from all devices at your home and Wi-Fi router has a weak password, your neighbor can easily steal your data. You will certainly get very low speed if 2-3 devices use your router simultaneously. In simple words, you need to secure your Wi-Fi router using strong password. When it comes with Wi-Fi security, MAC filtering comes first.

As you cannot use one network card in more than one device, two devices cannot come with same MAC Address. Therefore, you can easily enable MAC filtering to block unauthorized devices to use your internet. If you enable MAC filtering, your router will check your device’s MAC Address and given MAC Address. If those two MAC Addresses do not match together, you cannot connect to the Wi-Fi router.

What if you forget the Wi-Fi password

If you have set up MAC Filtering and forgot the router’s control panel password, all you need to do is to reset your router. There is no other way to open the panel. Some people have claimed that they have successfully logged in by changing the MAC Address, but my personal attempt was failed.
