Requiring Windows 2000, XP or newer, NetStumbler functions best with a
supported wireless card. Determining precisely which cards are fully
supported can take some sleuthing.
NetStumbler fully supports cards based on the Proxim 8410-WD and
8420-WD, which have most commonly been sold under the names Orinoco
Classic Gold and Orinoco Gold. Other cards based around this chipset
include the Dell TrueMobile 1150, Compaq WL110, and Avaya Wireless
802.11b PC Card. Also supported are cards based on the Intersil (now
owned by Conexant) Prism and Prism2 wireless chipsets, such as the
popular D-Link DWL-650. Unfortunately, there is no single comprehensive
source of information on wireless card chipsets and retail models.
Seattle Wireless maintains a wiki, and NetStumbler hosts user-submitted
compatibility reports, although they do not indicate which chipset a
Wireless cards which are fully supported in NetStumbler are able to
report accurate noise and signal strength levels. The latest 0.4 version
of NetStumbler partially supports most wireless cards, but those without
full support will not be reliable for noise and strength readings, and
may cause instability in NetStumbler itself.
