I use a combination of the following tools:
NetStumbler
http://www.netstumbler.com
scanning software for Hermes Chipsets. I have it running on a Windows 98 laptop with an Orinoco Gold card. Its a very full-featured war driving tool that is useful for WLAN engineers as well. It can be used to assist in the identification of wireless networks by sniffing SSIDs. It tells you which APs or Ad-Hoc peers are WEP encrypted. It can be used for signal strenth and noise measurements of a system.
APSniff
http://www.bretmounet.com/ApSniff/
simple scanning software similar to NetStumbler for Prism II Chipsets. It, however, lacks some of the more advanced features of NetStumbler. It works well for checking out a network using a consumer card (Prism II cards appear to have less sensitive receivers) It runs on Windows 2000 and XP. I have it running on a laptop with a Netgear MA401 card. It can be used to assist in the identification of wireless networks by sniffing SSIDs. It can be used to a limited extent for signal strenth and noise measurements of a system, but it does not have a graphical display yet.
Etheral
http://www.ethereal.com/
a GUI sniffer which understands 802.11b frames. I have it running on a Windows 98 laptop. It seems to miss some of the low-level control frames, but otherwise works very well.
I have heard of the following tools but have not demoed them yet due to platform (cards and operating systems) and cost issues:
WinProp
http://www.awe-communications.com/
A site planning tool that inputs floor plans of a building and positions APs according to information like signal propagation decay for various wall materials.
Mognet
http://chocobospore.org/mognet/
Mognet is a free, open source wireless ethernet sniffer/analyzer written in Java.
Prism2Dump
http://www.dachb0den.com/projects/prism2dump.html
a tcpdump-like protocol analyzer for 802.11 network traffic
WildPackets AiroPeek
http://www.wildpackets.com
a comprehensive packet analyser
WLANbit TriCycle
http://www.wlanbit.com/
A site planning tool
Berkeley Varitronics Systems - Grasshopper
http://www.bvsystems.com/
Grasshopper is a handheld device useful for testing IEEE 802.11b networks. Berkeley Varitronics Systems claims that their instrument can identify mutipath (dead spot from multiple copies of the same signal due to reflections), CW (continuous wave) sources such as microwave ovens, and FH (Frequency Hopping) sources such as Bluetooth and Cordless phone devices. However, It does not offer any storage for post processing of the data.
What other tools have you all found that are worthwhile looking at?
