Works just fine. Or, back up the app into some other folder, such as a backup folder, before running the Mountain Lion install. But not after the first time. Why did this change after the first time running it? How did that happen, and can I somehow change this to the UK? Presumably France.

New Features!

He must be on vacation. Had the same problem as Perry, solved by Naru, got what seemed like odd result, virtually straight line yellow at 50, virtually straight line green at bottom. Any help would be appreciated because my wifi needs tweaking. This article motivated me to optimize the location of my network devices and I could improve the signal strength — so thanks! Now I would like to know if you have any suggestions on how to optimize browser and web page loading.

Very annoying. Also be sure to check out NetSpot App — its the same idea but has a bit more features.

Have latest lion os, cant find the utility, how do i get to it? Info from article didnt find it, thanks Jas. That said, higher is always better and you can always reduce noise.

Netspot offers a detailed heat map that allows the user to identify signal strength in their surrounding location.

What really sets this app apart from the crowd is the depth of its reports, ease of use and network information. The program color codes areas of signal strength, with weak signals being highlighted by purple or blue. The scalability of the heat map renders NetSpot ideal for both home and office users.

As one of the best mid-level tools on this list, WiFi Explorer is a solid alternative for beginners and experienced users alike.

When a user launches WiFi Explorer they can start to locate local wireless networks immediately. Once this occurs, the user can flick through the networks identified via the use of the on-screen tabs. Users can look through everything: network details , signal strength , 2. You can simply set the app to measure signal strength and it will produce a graph as you walk around your building.

Unlike many other tools on this list, WiFi Scanner also enables the user to detect unauthorized devices on the network through the use of an IP scanner. This makes it a great tool for overall network transparency. Rather than opting for a visual display, iStumbler scans for wifi networks and puts them into a list.

This list is updated in real time so you can click on any networks you see and view more detailed information like dBm values. Unfortunately, the free version bombards the user with endless popups encouraging them to upgrade. The depth of the signal data and the ease of use of the platform makes this a good choice for users who are new to the world of wifi analyzers.
