Looking for a good WiFi network tester for troubleshooting airtime and interference

  • Updated 3 years ago
Any ideas? I already have a site in place that was not properly done with a site survey so I would like to know a good tool so that I can walk around the building where the AP's are and troubleshoot interference. I've found a WiFi tester by Fluke networks but before I look further into it I wanted to know what would the professionals over at Aerohive suggest?

Hi Arison
A good spectrum analyzer will tell you more about layer1 issues. We use the solution of Metageek, wi-spy. Another application that we use for checking the health of the network is Ekahau Site Survey. All of this is quit expensive if you need it just to check your own network, looking for a company to do it for you will be less expensive.

I use Wifi Analyzer, a free app available in the Apple Store or Google Play Store.

Hi Arison,

We use the Airmagnet tool from Fluke Networks for the Site Survey and the Spectrum Analyser, also from Fluke Networks to analyse the interference.
Both are very good tools and give you an excellent picture.

Therefore you can use the built in Spectrum Analysis throug the APs.

Regards,
Maurice

Are these devices or Apps ? because we have 1 to 1 AP per room with many changes to turning off 2.4Ghz etc but I'm still having interference issues. I would like to walk around and pin point all the errors.

What we use is specialized sofware installed on a Windows notebook.
You also have a Spectrum analyser from Fluke on a hand based device like this:

The app I suggested uses your phone/tablet to pick up and analyze the relative strength of all the wireless signals around you, and graphs them for you.  Check it out!

I tried that on my previous android phone but besides the channeling on it I couldn't get much info out of it for example which is the closest AP to me etc.

You really need three unique tools:

1.  Site Survey Application
The site survey application will record 802.11 signal strength (both your access points and neighbouring ones), signal to noise ratio, areas of contention, etc and place them on floor plans.  AirMagnet Site Survey and Ekahau Site Survey are two very good examples of this type of application.

2.  Spectrum Analyzer
A spectrum analyzer detects non-802.11 interference and classifies it.   AirMagnet SpectrumXT and Metageek's Chanalyzer and Wi-Spy are two very good examples.  If you are new to wireless then AirMagnet's SpectrumXT may be a better option as it automatically identifies the interference types for you.  Ekahau's Spectrum Analyzer is an OEM'd Metageek Chanalyzer and Wi-Spy.

3.  Protocol Analyzer
A protocol analyzer will record the 802.11 frames and report any issues.  Normally you configure the protocol analyzer so it knows how you have configured the wireless network.  AirMagnet's WiFi Analyzer is an excellent example of this type of application.
