Appendix A – Channel and Data Rate Selection
This section provides basic information for selecting fixed data rate and channel frequency in the
NDIS driver. This becomes necessary if you want to test the 802.11a Wireless LAN Network
Adapter at a specific channel with the rate adaptation controls turned off.
To select channel frequency and data rate in the Windows environment with NDIS driver installed:
1. Click Start, Run, and type "regedit” to open Registry Editor
2. For Windows 2000 and Windows XP, locate the following registry key, and select Find from
the Edit menu:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
For Windows 98SE and Windows Me, locate the following registry key, and select Find from
the Edit menu:
HKEY_LOCAL_MACHINE\System\CurrnetControlSet\
3. Type "clist" and click Find Next to find the registry key. Note that if you have multiple
instances of the 802.11a Wireless LAN Network Adapter installed, for example, the NDIS
driver is installed more than once, then you will need to click Find Next to locate the current
instance of the device that is in use.
4. Double-click on clist and enter the channel number in the "Value Data" field. Enter the IEEE
channel number from the following table. For example, enter 40 to select channel frequency
of 5.20 GHz. The channel numbers follow the IEEE format where:
Channel Frequency (in GHz)= 5 + 0.005 *(Channel Number).
