The Basic Configuration box contains the following settings:

•Channel: The channels available in the Channel list box depend upon the selected adapter. Since channel numbers 1, …, 14 in the 2.4GHz and 5GHz bands overlap and there are center frequncies (channels) that do not have channels numbers, each available channel is given by its center frequency. Where applicable, the BG or A channel numbers are also given. All of the channel center-frequencies supported by the selected adapter will be made available in the Channel list. The bandwidth of each channel is 20MHz.

•Extension Channel: For 802.11n adapters, one can use the Extension Channel list create a “wide” channel. The choices are -1 (the preceding 20MHz frequency band), 0 (no extension channel), or +1 (the succeeding 20MHz frequency band). The channel of the additional frequency band is called the extension channel. The Extension Channel list box lets you choose a valid extension channel (above or below) for a given channel (See Figure 2). Not all channels have above and below extension channels. For example, BG channels 1, 2, 3, and 4 do not have a -1 (below) extension channel. The reason is that the center frequencies of the primay and extension channels need to be separated by 20MHz. So if 4 were the primary channel, channel 1 (which is the lowest BG center frequency) is only 15 MHz below channel 4.

•Capture Type: 802.11 frames only, 802.11 frames plus radio information (See Radiotap), or 802.11 frames plus the Per-Packet Information (PPI) header (See Downloads for the current PPI
