Helped tremendously in apartment building

I had just purchased my Airport Time Capsule and was pretty disapointed with the wifi of the unit after setting it all up. The speeds through ethernet were incredible (I was previously using an Airport express…not gigabit ethernet) but the speeds over wifi were fairly poor. I would get at least 100 mbps down via ethernet but on wifi i would maybe get 50 mbps down. After opening up Wifi Explorer I discovered that even though I had the wifi channel setup to automatic, it chose a channel that had 15 other wifi networks on it. After switching it to a channel that none of my neighbors were using, my wifi speed jumped all the way up to 100 mbps, just like the ethernet speed that I get. Seriously cannot express how happy I am I discovered this app. Well worth the price. Thank you so much for creating this app!

Great little tool, still not perfect on Yosemite

This is an incredibly useful app to see wifi networks in your area and determine what kind of traffic exists in your area. One really underrated feature of this program is how clean the interface is compared to other programs both PC and Mac. After using this one for so long, similar programs just look plain ugly in comparison.

My only complaint is that it’s still got some hiccups in Yosemite, and sometimes crashes on me. It’s definitely much improved (and the developer releases frequent updates to correct issues), so I don’t expect the issues to last too much longer.

All in all, it’s a must-have program for scanning wifi networks.

A Wonderful Utility to Have In Your Arsenal

WiFi Explorer is a great application to have available to take a look at what is going on with and around your WiFi network. It lets you clearly see which channels are being used nearby so that you can select the least used ones for your network to operate on as well as viewing all of the signal strengths of networks in range of your computer. For anybody needing more information about your WiFi network, it’s a must have tool.

It’s also just fun/cool to be able to gather so much information about what is going on with all of the WiFi networks around you and is well worth the price.
