Depressing! 😔

Depressing… not the software… but the report it generates. There’s no need to shoot the messenger. Most routers, in my very crowded neighborhood, broadcasting in the 2.4 GHz range. It’s not the fault of WiFi Explorer that my neighborhood is crowded. It’s not the software’s fault that my router doesn’t broadcast in the 5 GHz range.

What WiFi Explorer does is make it plainly obvious why the WiFi signal is fairly inconsistent. The software makes it obvious that I should upgrade, move or continue to tolerate weak WiFi signal.

This software works well. It’s a great way to visualize what’s going on. It’s updated constantly. The updates are so frequent, it’s borderline annoying. So if you like apps that are supported, this app has a strong history of updates.

It’s almost like a super power. WiFi Explorer lets you see what your eyes cannot.

It’s really worth it.

You spent a lot on your mac, you spent a lot on your wifi router. Your wifi router is probably auto-assigning a very congested wifi channel. This is a great tool to find the channels that have a little more breathing room.
Also a great tool to monitor your wifi signal as you walk around the house.
This tool and the authors other tool wifi signal are the best i’ve found.

Best wifi troubleshooting app for OS X

This app is fantastic! Adrian is a pillar of the community and his ‘side projects’ are more polished and updated more frequently than most commercial applications I’ve used. If you like this, check out AirTool. Thanks!!
