CHANNEL
Channels are the spectrum range where your wireless signals
are transmitted. The default is channel 1. However, to
maximize performance for your wireless network, another
channel may give you better performance. Select the channel
you wish to use (channel 1 through 11) from the pull-down menu.
Note: For better performance, avoid using channels
occupied by other AP’s in the area.
RTS THRESHOLD
RTS (Request to Send) Threshold is the packet size by which
the router will judge whether to activate the RTS mechanism.
When RTS is activated control packets are used by the access
point to regulate the traffic giving the various connected clients
86
Clear To Send (CTS) messages before data can be transmitted
from a client. RTS is used to avoid collisions.
The default value is 2432, which is quite large so that RTS is not
activating in most cases. When RTS is activated, overall
performance decreases due to the associated overhead
incorporated into the packets. In most network environments,
RTS is not necessary.
FRAG THRESHOLD
Fragmentation Threshold is the size at which packets are divided
into smaller packets to be transmitted on an 802.11 wireless LAN.
This fragmentation is done to improve performance when
transmitting large files over the wireless network. The
fragmentation threshold is determined on a station-by-station
basis.
TRANSMIT BEACON
For security you can choose to disable the broadcasting beacon
signal identifying your access point.
WEP ENCRYPTION
To make your network more secure, you may choose to use
Wired Equivalent Privacy (WEP). WEP is an encryption
scheme used to protect your wireless data communications.
WEP uses a combination of 64-bit or 128-bit keys to provide
access control to your network and encryption security for every
data transmission. The
WNR2004 Wireless AP/Router
supports both 64-bit WEP and 128-bit WEP. To connect all
computers with a Wireless LAN using WEP, each AP and client
in the network must use an identical 64-bit or 128-bit WEP key.
In simple terms, a 128-bit key will give you a more secure
network than a 64-bit key.
