All of the internal AirPort hardware is supported as well.An awesome table comparing many of the tools mentioned in this post is available here Kismet Kismet is an 802.11 layer2 wireless network detector, sniffer, and intrusion detection system. USB Prism2 is supported as well, and USB Ralink support is in development. KisMAC supports several third party PCMCIA cards – Orinoco, PrismII, Cisco Aironet, Atheros and PrismGT. It has an advantage over MacStumbler/iStumbler/NetStumbler in that it uses monitor mode and passive scanning.
KisMAC KisMAC is an opensource and free stumbler/scanner application for Mac OS X.
iStumbler iStumbler is the leading wireless discovery tool for Mac OS X, providing plugins for finding AirPort networks, Bluetooth devices, and Bonjour services with your Mac.
This implementation also prevents MacStumbler from detecting wireless stations or hidden networks because they don’t respond to probe requests. MacStumbler doesn’t currently support any kind of PCMCIA or USB wireless device.MacStumbler works like NetStumbler and relies on responses to probe requests to discover access points. MacStumbler requires an Apple Airport Card and MacOS 10.1 or greater. Additionally, MacStumbler can be used for “wardriving”, which involves co-ordinating with a GPS unit while traveling around to help produce a map of all access points in a given area. It is mainly designed to be a tool to help find access points while traveling, or to diagnose wireless network problems. MacStumbler MacStumbler is a utility to display information about nearby 802.11b and 802.11g wireless access points. Istumbler Alternatives For Mac Air Alternatives to NetStumbler Istumbler Alternatives For Mac Free Access points are detected by recording which ones respond to probe requests, which also means it can not detect wireless stations since they don’t respond to probe requests. NetStumbler does not detect wireless stations.Normally, this isn’t a big deal but this means in a 100% no wireless zone NetStumbler can be detected. It uses Active Scanning and sends out a probe request about once a second, and reports the responses.
NetStumbler NetStumbler (also known as Network Stumbler) is a free/”beggarware” tool for Windows that can detect WiFi/Wireless LANs using the 802.11b, 802.11a and 802.11g WLAN standards.
