Step 3: Understand exactly what 802.11 Channel and Band your client device is using before setting up your capture. Step 2: Use a separate device to act as your wireless sniffer - you cannot take a good wireless sniffer trace if it is running on the device under test (the client machine you are trying to get a wireless trace of).

This will allow your sniffing device to capture a good approximation of what your client device is hearing over the air. Step 1: Since the sniffing device, client device and AP are all using RF generating radios for transmission or reception, it helps to have your wireless sniffer close to your target device (the client machine). With Wireless sniffing it helps to have an idea of what you are really trying to do - you are trying to capture the raw wireless frames from over the air, as seen by the wireless sniffing device itself. But there are a few things to bear in mind that will help simplify and speed up this process.

The process of collecting a good wireless sniffer trace, in order to analyze and troubleshoot 802.11 behavior, can be a difficult and time consuming operation.
