Used to work well...

It's broken. Hasn't been updated in a while.

Show me what connects me

WIFI is inherently invisible and with this hard to grasp. Minimal information provided by MacOS or professional tools that are diffciult to navigate both don’t offfer a viable solution to navigate wireless connections for amateurs with a reasonable half-knowledge.

I have used many versions of iStumbler over the years to resolve WIFI issues and this is finally an Apple-approved version. Well worth the money if you use wireless connections.

Great product!

I was a bit intimidated as to what a tool like this would require from me in terms of learning curve etc. Very easy to use, poweful. Impressed by all the information that it provides.
