If possible, can you give me info that which outside-wireless-adapters
are suitable for Ethereal? Thank!
If you're running Ethereal on Windows, as far as I know, *no* wireless
adapter is suitable for "monitor mode" capturing; no vendor's driver
supports monitor mode, as far as I know, and the drivers that
WildPackets and Network General have do but WildPackets and Network
General don't say how to make them do so (and probably don't support
using those drivers in other applications, and might even require that
you buy the application in order to use the driver).
I don't know whether any of them are suitable for promiscuous mode
capturing.
If you're just capturing traffic going to or from the machine running
Ethereal, and broadcast/multicast traffic that machine receives, then
most adapters *should* work - but don't run in promiscuous mode:

The WLAN capture setup page on the Ethereal Wiki:

A page that lists various wireless cards and how well they work with
WinPcap can be found at

If you're lucky enough to be running Linux, FreeBSD, NetBSD, or OpenBSD,
rather than Windows, see the section on the WLAN capture setup page for
your OS.
