Here are some general and universal guidelines for adjusting DNS settings on a wireless router.

STEP 1

Ensure that your modem and router are both properly connected, with an Ethernet cable extending from the router to the modem. Your modem should be transmitting an Internet connection and your router should be working to wirelessly extend this connection.

STEP 2

Access your admin panel or firmware software via instructions in the manual, as each router is different. This is typically done by entering an IP address in a web browser on a connected computer.

STEP 3

Scour your router’s settings for anything about the DNS server, sometimes called “DNS Server Settings” or simply “DNS settings.” This page can sometimes be listed underneath LAN settings. If you’re having trouble finding this settings page, check your router’s instructions or perform a Google search for your router and “change DNS server”.

STEP 4

Adjust the DNS server settings to your liking, adding any third-party DNS server you have access to.

STEP 5

Restart the router by unplugging it from a power source for around a minute and then plugging it back in. Once restarted, you should be good to go.
