The Wireless toolbar has the following controls:

 

•

802.11 Channel: allows the user to change the channel on which

 

 

the current AirPcap adapter captures. The channel can be changed

 

 

at any time, even while Wireshark is capturing.

 

•

Offset: for AirPcap N, allows the user to set an extension, or

 

 

“wide” channel.

 

 

 

Tip:

When real-time packet updates are enabled

 

(Edit→Preferences→Capture→Update list of packets in real time),

 

switching from channel to channel allows you to see which

 

channels have traffic and which ones are unused.

 

 

 

 

 

•

FCS Filter: allows the user to select which packets the current

 

 

AirPcap adapter should capture: all the packets, only packets with

 

 

a valid FCS, or only packets with an invalid FCS. This feature can

 

 

be used to get a quick check on the quality of the transmission on

 

 

the channel and/or the quality of the adapter’s reception.
