7. Meraki WiFi Stumbler

This is a simple web-based stumbler, freely available on the Meraki website. It runs in most browsers on Macs and PCs, and even works when offline. It displays most of the basic wireless details (with signal levels in percentages) and offers a bar graph of access points per channel.

It doesn't allow any customization and doesn't offer any additional functionality beyond displaying the network basics and letting you perform searches of the data. However, this stumbler is still useful if you want to check wireless signals from a computer that doesn't already have a stumbler installed.

8. KisMAC

If you're a Mac user, you might consider using the KisMAC stumbler and security tool, similar to Kismet. It also reveals "hidden" SSIDs. Along with the other basic details, it can show the access point's clients (with MAC Addresses, IP addresses and signal strengths). Plus it reports the noise levels and gives you the signal-to-noise (SNR) values. It also supports GPS and mapping, and PC access point import and export. It even includes tools to attack Wi-Fi networks for penetration testing.
