Pretty unstable app. I would NOT buy it after 3-day usage experience. I am pretty sure there are better (and free) alternatives.

iStumbler pricing is too aggressive, leaving iStumbler naked to be copied and raped commercially by bottom feeders like Koingo Soft (AirRadar). I bought a license in solidarity (iStumbler is great software) but as most of my machines are on Snow Leopard, I'm still mainly using the free version and didn't have to. Zero to $25 is obnoxious. If being obnoxious was your goal, you've succeeded. In the long term, encouraging competition is not good business practice. My new lower review is based on the $25 price tag. The software still works fine. I hope the developer finds a better compromise between thinking about his users and thinking about himself. $20 was still okay for a simple but nifty utility which works on all your computers.

Alright folks, help me out here. If all I’m really wanting is something to help deconflict from other Wi-Fi networks in the area, wouldn’t Apple’s included Wireless Diagnostics tool work just fine? And save me 25 bucks to boot now that the iStumbler developer has decided to start charging to put a pretty wrapper on something Apple already provides for free? Before I get flamed, of course I know iStumbler does other things but I’m just interested in identifying the local Wi-Fi networks and their channels. Do a spotlight search on “Wireless Diagnostics” and open it up. Click on “Scan Now” in the lower right and voila, Apple’s cool little app finds all the 2.4 and 5GHz networks within range and the first column on the left makes suggestions on the 2.4 GHz and 5 GHz channels which are least used (Best choices if you don’t want to let Apple automatically select an appropriate channel). Plus if you pull down the Wireless Diagnostics “Window” menu, there’s other cool things in the app’s toolbox like a sniffer function.
