NOTE: The Tools > Wireless options are only available if a
wireless LAN adapter is the currently selected adapter, the correct
driver is installed, and you are not operating in Local Mode. You
can change the currently selected adapter and the Local Mode
setting using the File > Adapter Settings command. See Installing
Sniffer Portable Professional for information on installing the correct
driver for wireless adapters in both Windows XP and Windows Vista.
Configuring Surf Settings
Use the Tools > Wireless > Surf Settings > Topology Surfing dialog
box (Figure 4-3) to select the wireless LAN channels you would like
Sniffer Portable Professional to monitor. For each wireless topology
supported by your wireless adapter, you can select individual channels
for monitoring, as well as the amount of time to monitor them.
The Topology Surfing dialog box consists of two main panels:
The left panel lists the channels available for selection. Channels
are listed independently by topology (for example, 802.11A,
802.11B, and 802.11G) – use the 802.11 drop-down to change the
selected topology. You can select channels in the left pane and click
the Add button to move them to the Selected panel.
The Selected panel lists the channels currently selected for
monitoring. Sniffer Portable Professional monitors each of the
channels in the Selected panel in a cycle for the time specified by
its Surf Time field before moving on to the next selected channel.
