Have Mac notebook, will travel. As Mac (and PC) troubleshooter, I move from office to office, network to network, and WiFi to WiFi multiple times every day of the week.
My Mac’s Airport display of networks is about a foot long. So I rely on a couple of 3rd party apps to capture network strength when I’m trying to logon to a nearby network.
Network Strength is a free Mac app that gives you valuable information about the network you’ve connected to. And it lives in the Mac’s Menubar so you can easily find what you need. It’s a click away.
One click gives you a look at the network’s WiFi strength to your Mac. Strength is measured in a percentage, as is noise.
The IP addresses are also displayed.
Wait. Don’t you get the same thing by looking at the Airport WiFi strength meter in the Mac’s Menubar. Yes. And no. The additional information can be had through opening the System Preferences, and clicking on Network, then the network settings.
Network Strength gives it to you through the Menubar with a click.
Even more useful to me when looking for networks is the venerable iStumbler, the app that helps you find local networks, Bluetooth devices, location information, even local Bonjour services.
iStumbler gives the type of network, security settings, mode, name, signal strength (with a nice bar), noise level and channel, and the MAC address.
The only negative is that iStumbler is a stand alone app and doesn’t reside in the Menubar. Still, it’s free and gives more information to WiFi hunters.
