• Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many
broadband ISPs restrict access by allowing traffic only from the MAC address of your

Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the

Erasing Your Settings” on page 4-4).
• Press the Wireless On/Off and WPS buttons on the side panel of the router simultaneously for
6 seconds to reset the router to its factory default settings. Use this method for cases when the
administration password or IP address is not known.

the router:
1. Press and hold the Wireless On/Off and WPS buttons simultaneously until the Power LED
turns red (about 6 seconds).
2. Release the Wireless On/Off and WPS buttons. The LED blinks red three times and then turn
green when the router has reset to the factory default state. Wait for the router to reboot.
