Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access point. This
would significantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
Don't let your next-door neighbors or intruders connect to your wireless network. Encrypt your wireless network by turning on the WPA or
WEP security feature on the router. Refer to the product manual for detail information on how to set it up.
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 DWR-956M wireless network USB 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 USB adapters.
All the adapters must be in Ad-hoc mode to communicate.
