How to configure a TP-Link Archer C9

  • Updated


Here’s how to set up your TP-Link Archer C9 on the Pentanet network, let's go!


Before you begin

You'll need to know what technology type your Pentanet service uses as the steps vary between technology types. You'll also need to know your Pentanet PPPoE authentication username and password. 

You can find this information in the welcome email we sent you, your Customer Portal under the Services > Settings section, or just reach out to our friendly team who can assist if you're unsure.


Configuring your TP-Link Archer C9

  1. Connect a laptop or Desktop computer directly into any of the yellow LAN ports using an ethernet cable. (You can also use wi-fi to set up your device, but we recommend ethernet.)
  2. Make sure that you’ve connected your Pentanet NBN or Fixed Wireless service to the blue WAN port of the device.
  3. Using a web browser navigate to When prompted to login, use admin for both the username and password. If the default login doesn’t work you may need to factory reset your device.
  4. Choose Basic from the top menu, then, choose Internet from the left hand side menu.
  5. On the Internet page, change the Internet Connection Type to PPPoE
  6. Enter your Pentanet PPPoE username and password. Note: Your username should be in all lowercase and your password will be case sensitive.
  7. Choose Save to apply the settings and you should now be online.

Once complete, your settings page should look similar to this:


Your TP-Link router has two Wi-Fi networks which broadcast on different frequencies - 2.4GHz and 5GHz. 5GHz can reach faster speeds but doesn’t penetrate walls well. 2.4GHz travels farther, but often won’t be as fast. We recommend using the 5GHz network when you’re nearby the unit, or the 2.4GHz if you’re in a different room or further away.
