The Advanced Wireless Settings screen is where basic wireless configuration is performed.

Basic Rates	The basic transfer rates should be set depending on the speed of your wireless network.  Your must select 1-2 (Mbps) if you have older 802.11 compliant equipment on your network.
Control TX Rate	Select all the supported rates at which the Router will communicate with your wireless network.
Preamble Type	The preamble defines the length of the CRC block for comunication between the Router and the roaming network adapter.  (High network traffic areas should use the shorter preamble type.)
Authentication Type	You may choose between Open System, Shared key, or Both.  The Authentication Type default is set to Open System, in which the send and the recipient do not share a secret key. Each party generates its own key-pair and asks the receiver to access the randomly generated key.  Once accepted, this key is used for a short time only.  Then a new key is generated and agreed upon.  Shared key is when both the sender and the recipient share a secret key.
Beacon Interval	This value indicates the frequency interval of the beacon.  A beacon is a packet broadcast by the Router to kepp the network synchronized.
DTIM Interval	This value indicates the interval of the Delivery Traffic Indication Message(DTIM).  A DTIM field is a countdown field informing clients of the next window for listening to broadcast and mulitcast messages.
Fragmentation Threshold	This value indicates how much of the Router's resources are devoted to recovering packet errors.
RTS Threshold	This value should resmain at its default settings of 2,346. Should you encounter inconsistent data flow, only minor modification are recommended.

For most users, the default values for the Router should be satisfactory. The Router can be used in most network environments without changing any of the values. It is recommended that these values do not change, unless you know what you are doing.
