	~~You can~~ filter packets at the wireless card level, ~~using~~ packet ~~filtering. Specifically, create~~ filters ~~that use~~ the ~~BPF (~~Berkeley packet filter) syntax.		To filter out packets at the wireless card level to reduce the CPU load during a capture, you can use packet filters with the Berkeley packet filter (BPF) syntax.

			Hree's an example that would only look for packets to a certain host and port (port 80 is HTTP traffic):

	<pre>		<pre>

	</pre>		</pre>

	~~First, the~~ primitives and ~~the~~ operators:		The syntax consists of primitives and operators.

	~~primitive: dst host 192~~.~~168.0.10~~

	~~operator: &&~~

	~~primitive: tcp port 80~~

	~~Now qualifiers and ID portion:~~

	primitive: dst host 192.168.0.10		A primitive is something like <code>dst host 192.168.0.10</code> or <code>tcp port 80</code>.

	~~qualifier: dst~~		An operator is something like <code>&&</code>.

	~~qualifier: host~~		The primitive itself consists of qualifiers and IDs.

	~~id:~~ 192.168.0.10		The primitive <code>dst host 192.168.0.10</code> has the qualifiers <code>dst</code> and <code>host</code> and the ID <code>192.168.0.10</code>.

	I guess that SSL certificates differ in how much information gets broadcast, because my cheapie self-signed certificate made it a lot easier to see the destination of HTTPS traffic destined for my website. It was not routed through Verisign.

	It is usually better to capture everything and ~~hide packets using~~ display filters, instead of applying capture filters on the capture level.		If your wireless card and CPU can handle a large amount of traffic, It is usually better to capture everything and use display filters to show different packets, instead of applying capture filters on the capture level. Capture filters are better if you're targeting your capture at a specific range of devices, a specific channel, or particular protocols.

	Use filter expression dialogue to create packet display filters.		Use filter expression dialogue to create packet display filters.
