Security Mode. Select the security method you want to use, WPA-Personal, WPA2-Personal, WPA2-Mixed, 
WPA-Enterprise, RADIUS, or WEP. (WPA stands for Wi-Fi Protected Access, which is a security standard stronger 
than WEP encryption. WPA2 is a stronger version of WPA. WEP stands for Wired Equivalent Privacy, while RADIUS 
stands for Remote Authentication Dial-In User Service.) Refer to the appropriate instructions below. For detailed 
instructions on configuring wireless security for the Access Point, turn to “Appendix B: Wireless Security.” To 
disable such security, select Disabled.

The Wireless - Advanced Wireless Settings Tab
This screen allows you to configure the advanced settings for the Access Point. In most cases, these settings do 
not need to be changed.
Advanced Wireless
You can change the data transmission and output power settings for the Access Point.
Authentication Type. Select the authentication method you want the Access Point to use, Shared Key or Open 
System (Default). Shared Key is when both the sender and the recipient share a WEP key for authentication. 
Open System is when the sender and the recipient do not share a WEP key for authentication. All devices on your 
network must use the same authentication type. In most cases, keep the default, Open System (Default).
Basic Rates. This setting is not actually one rate of transmission but a series of rates that are advertised to the 
other wireless devices in your network, so they know at which rates the Access Point can transmit. At the Default 
setting, the Access Point will advertise that it will automatically select the best rate for transmission. Other 
options are 1-2Mbps, for use with older wireless technology, and All, when you wish to have all rates advertised. 
The Basic Data Rates are not the rates transmitted; the rates transmitted can be configured through the 
Transmission Rates setting on this screen.
Transmission Rates. The range is from 1 to 54Mbps. The rate of data transmission should be set depending on 
the speed of your wireless network. You can select from a range of transmission speeds, or you can keep the 
default setting, Auto (Default), to have the Access Point automatically use the fastest possible data rate and 
enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the 
Access Point and a wireless client.
Transmission Power. You can adjust the output power of the Access Point to get the appropriate coverage for 
your wireless network. Select the level you need for your environment. If you are not sure which setting to 
choose, then keep the default setting, Full (Default).
CTS Protection Mode. The CTS (Clear-To-Send) Protection Mode function boosts the Access Point’s ability to 
catch all Wireless-G transmissions but will severely decrease performance. Select Enable if you want to 
permanently enable this feature, or keep the default, Disable, if you want to permanently disable this feature. In 
most cases, CTS Protection Mode should remain disabled, unless the Wireless-G products are experiencing 
severe problems trying to transmit to the Access Point in an environment with heavy 802.11b traffic.
Frame Burst Mode. Enabling this option should reduce overhead and enhance your network performance, 
depending on the manufacturer of your wireless products. If you are not sure how to use this option, keep the 
default, Disabled.Figure 7-20: Wireless - Advanced Wireless

Antenna Selection. This selection is for choosing which antenna transmits data, left or right. If you are not sure 
which antenna to use, keep the default, Diversity, to increase reception.
Beacon Interval.  This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by 
the Access Point to keep the network synchronized. A beacon includes the wireless networks service area, the 
Access Point address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and 
the Traffic Indicator Message (TIM).
DTIM Interval. This value indicates how often the Access Point sends out a Delivery Traffic Indication Message 
(DTIM). Lower settings result in more efficient networking, while preventing your PC from dropping into power-
saving sleep mode. Higher settings allow your PC to enter sleep mode, thus saving power, but interferes with 
wireless transmissions.
Fragmentation Threshold.  This specifies the maximum size a data packet can be before splitting and creating 
a new packet. It should remain at its default setting of 2346. A smaller setting means smaller packets, which will 
create more packets for each transmission. If you have decreased this value and experience high packet error 
rates, you can increase it again, but it will likely decrease overall network performance. Only minor modifications 
of this value are recommended.
RTS Threshold.  This setting determines how large a packet can be before the Access Point coordinates 
transmission and reception to ensure efficient communication. This value should remain at its default setting of 
2347. Should you encounter inconsistent data flow, only minor modifications are recommended.
