    1.2 Applications Your can have the following networks using the NBG2105: • Wired. You can connect network devices via the Ethernet ports of the NBG2105 so that they can communicate with each other and access the Internet. • Wireless. Wireless clients can connect to the NBG2105 to access network resources. You can use WPS (WiFi Protected Setup) to create an instant network connection with another WPS- compatible device.

  • Page 14: Resetting The Nbg2105

    If you forget your password, you will have to reset the NBG2105 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG2105.

  • Page 15: The Clone Mac Button

    Make sure the power LED is on (not blinking). Press and hold the Clone MAC button for more than five seconds to reset the NBG2105 back to the factory default MAC address. The Clone MAC Address in the WAN screen shows 000000000000 to indicate the NBG2105 is using the factory default MAC address.
