Helped Me Optimize My Network!

Have to say, this is one of the best apps I’ve ever downloaded from the App Store. Not only is it fun to watch all the details of all the wi-fi networks your computer is detecting, but it will help you determine optimal wireless router and/or computer location in your home and wi-fi channel selection to avoid interference with other wireless networks in your area.

I first downloaded it on my iMac to see why my network wasn’t running so smoothly and saw the channel conflicts with not only my neighbor’s wi-fi networks but also with my own HP Officejet AirPrint-enabled printer and DSL modem’s wireless network (I had my primary Apple AirPort Time Capsule and the DSL modem wireless networks active). I then downloaded it again on my MacBook Air and moved throughout my house to see why both of my AppleTV’s seemed to not download as fast as they should and was able to make some changes to fix that. Finally, I downloaded it again (all for free…only have to pay once as long as you log in using the same AppleID on each computer) on my wife’s iMac to see why she was having slowdowns and made another tweak.

Very professional interface…a beautiful app that works extremely intuitively…anyone can see what’s going on with their wireless network environment. Major kudos to the developer! I assure you, you can’t go wrong paying a measly $2.99 for this great app.

You can stop

I’ve been looking for something like this to diagnose my network. Noticing that my old Wifi router signal was getting weaker over time, I bought a nice replacement (ASUS RT-AC68R). Wanting to maximize my investment, I searched for an iOS or Mac solution to watch the Wifi signals in and around my house to see where and how to set things up and get the best results. WiFi Explorer is exactly what I was looking for and it does the job elegantly and precisely. I’m a notorious spendthrift when it comes to apps, but I didn’t hesitate to pay full price for this one and I’m not disappointed. Very highly recommended.

If you’re looking for an app to see what’s up with your neighborhood area wifi, you can stop looking. You’ve found it.

FWIW: I am not in any way associated with the app or its developer. Just a very satisfied customer.

Excellent app

i work for an IT company and i use inSSIDer on windows for exploring wireless networks. I often use my personal macbook though and inSSIDer was not a good optino for OS X. This app does everything i would like it to. The only one thing i wish it did, and this is a small thing but useful, is if i could show the 2.4 and 5ghz channels at the same time side by side and to put the cherry on top would be having Signal Strength and/or Network details alongside the wireless views. inSSIDer on windows i can do Signal Strength and 2.4 and 5ghz side by side. That is very useful for me as i need to often take screenshots of these details and put them in work tickets.
