MacStumbler Crashes, get iStumbler instead
I had been using MacStumbler for the longest time to seek out Wireless Networks on my Macbook Pro. After moving into a new place and not yet having my wireless router set up I decided to launch the latest version and see if I could see any local wireless hubs to connect to; except it crashed every time I tried to open it, regardless of what I did it just crashed.
iStumbler to the rescue!
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.
