Security

Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.

Wireless Modes

There are basically two modes of networking:

•Infrastructure – All wireless clients will connect to an access point or wireless router.

•Ad-Hoc– Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer, such as two or more DWA-645 wireless network notebook adapters.

An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the wireless router or access point.

An Ad-Hoc network contains only clients, such as laptops with wireless notebook adapters. All the adapters must be in Ad-Hoc mode to communicate.
