If you are in the OSX/iOS ecosystem I like
Fing,
iTeleport (vnc client), &
NetAnalyzer for iOS, also this is a
cool utility if you have DD-WRT APs on your WLAN.
And built into OSX since 10.7.? is a really cool tool that is called Wi-Fi diagnostics under Lion, or
Wireless Diagnostics under Mtn Lion. You can get to it by holding down option key and clicking airport menu bar icon, then selecting wireless diagnostics. Then enter your admin user p/w, and once in the app do not click continue! Hold down Command-2 to get to the cool utilities!
I'm posting a link to a small gallery of images I just took instead of posting a bunch of pics direct to the thread.
I really wasn't sure what kind of malevolence, if any, could be turned my way by releasing full MACs or IP addresses to the world, so I just kind of cropped some of the pics, it probably doesn't make any difference. You already know my router can be easily found at 192.168.1.1.

The handiest part of that suite of utilities has been the ability to do quick, easy wi-fi site surveys from multiple places within my house/property. I've found that while a site survey from within the AP itself, at its location, might find X,Y,Z networks on whatever channels and strengths, if I'm often in location upstairs bedroom and outside patio using wifi, it behooves me to do a quick wi-fi survey at those places too. Long story short, "auto" channel selection at AP location might not be the best depending on where you do most of your wifi usage. . .just helps informed decision making & network planning (and I've greatly increased my wifi speed in the garage which I use for an hour or more a day, with no physical changes to my APs, just by doing fresh surveys and adjusting channels, tx/rx powers, etc, accordingly).
I mention this only to those who have never done multiple wifi surveys of their home or whatever,
Inssider has similar, if not better in some places features. But, OSX users you may have built in what you need already? Inssider is available at
Mac app store for OSX for $4.99 too. I downloaded
NetSpot the other day, haven't tried it yet, but it looks really interesting for doing low level survey work with nice google sketchup style layout. I have
Kismac &
iStumbler on my mac, but don't think they are fully supporting new hardware and haven't used either much as of late.
I also use
iStat Pro widget for OSX on all my Macs to so I can quickly do a four finger swipe to the dashboard and monitor my true ethernet and/or wifi speed at that moment, especially if I'm testing something.
I've installed
Wireshark on my PC but don't really use it yet (too complex for me).
PS - You may or may not notice in some of those pics that my SSIDs all have the extension "_nomap". That forces google streetview cars and android devices
not to harvest your SSID's MAC & geolocation for their location services database. Unfortunately Apple collects similar info as well from iOS devices automatically and aren't as clear how they use it or how to opt-out, but this is a start.
