Troubleshooting

How do I connect my wireless devices to the DIR-879 router?

1. Open your wireless network utility that displays available wireless networks.

2. Select the Wi-Fi Network name you assigned in the wizard and connect.
Note: If you did not run the setup wizard or you reset the router to its default

settings, refer to the Wi-Fi Conguration Card included for the default Wi-Fi
Network Name and Wi-Fi Password.

You can also connect wireless devices to the DIR-879 router using WPS:

1. Press the WPS button on the DIR-879 for a minimum of three seconds.

2. Within one minute press the WPS button on your wireless device.

3. Allow up to two minutes to connect.

Note: Some devices may require you to log in to a utility to start the WPS process.

Refer to the user manual of the device you want to connect to the router if you do
not know how to start the WPS process.

How do I change the wireless settings on the DIR-879 router?

1. Open a web browser (e.g., Internet Explorer, Chrome, Firefox, or Safari) and

enter http://dlinkrouter.local./. You can also enter the IP address of the
router (192.168.0.1).

2. At the login screen, enter the router password you created in the wizard (the

password is blank by default).

3. From the navigation bar at the top of the Home page, go to Settings >

Wireless to create a new Wi-Fi network name (SSID) and Wi-Fi password.

What can I do if I forget my password?

If you forget your password, you must reset your router. Unfortunately, this
process will change all your settings back to factory default.

To reset the router, locate the reset button (hole) on the bottom of the unit.
With the router powered on, use an unfolded paper clip to press and hold the
button down for about 10 seconds. Release the button and the router will go
through its reboot process. Wait about 30 seconds to access the router.
