• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the device becomes unstable or even crashes. If you
forget your password, you will have to reset the Device to its factory default settings. If you
backed up an earlier configuration file, you would not have to totally re-configure the Device. You
could simply restore your last configuration.
1.4 Applications for the Device

Device’s Router Features
Configure firewall and filtering features on the Device for secure Internet access. Set the firewall to
allow responses from the Internet for traffic initiated from your network and block traffic initiated
from the Internet. This blocks probes from the outside to your network, but lets you safely browse
the Internet and download files.
Use the filtering feature to block access to specific web sites or Internet applications such as MSN or
Yahoo Messenger. You can also configure IP/MAC filtering rules for incoming or outgoing traffic.
Use QoS to efficiently manage traffic on your network by giving priority to certain types of traffic
and/or to particular computers. For example, you could make sure that the Device gives voice over
Internet calls high priority, and/or limit bandwidth devoted to the boss’s excessive file downloading.
1.5 Wireless Access
The Device serves as a wireless Access Point (AP) to let wireless clients such as notebook
computers, smart phones, and tablets connect to the Internet without Ethernet cables.
