CTS 081: Wi-Fi Apps for Windows

We couldn’t do our work without the valuable apps used in the Windows operating system. That’s what we’ll discuss in this episode. Wi-Fi apps for Windows.

Here are the Wi-Fi apps for Windows that Rowell and I use regularly when we are working at client sites or for any other Wi-Fi project. We certainly have our favorite apps and there are some we use on special cases but take a look at the list below and let us know what you think in the comments.

Metageek Chanalyzer

  • Spectrum Analysis software (For more, listen to CTS066, CTS039, CTS073)
    • Required a piece of hardware to feed spectrum information to the software
      • Wi-Fi Spy dBx
      • Cisco CleanAir AP (much better resolution)
  • Simple and user friendly interface
    • Different views
      • Waterfall view
      • Current spectrum view
  • Ability to record spectrum analysis
  • Can scan both 2.4GHz and 5GHz bands at the same time (if proper adapter is used)
  • Built-in Wi-Fi network scanner
  • Present channel utilization
  • Link to Chanalyzer

Metageek Eye P.A.

  • A different way to analyze a Wi-Fi network
    • Very visual
  • Ability to capture packets (if proper Wi-Fi adapter is used – Airpcap Nx) and display different valuable statistics
    • How much the airtime is used? By who? You will see how much your neighbours affect you!
    • Compare size of packets with amount of data transfered. Helps to visualize that Wi-Fi generate tons of management traffic
  • Ability to import packet capture taken from other programs (Wireshark, AirTool, CommView…)
  • Ability to see the packets
    • With filter capabilities
  • Great to visualize issue and present to customers
  • Geat to gather statistics on how a Wi-Fi network is performing
  • Side note: Great tool to use to learn more about Wi-Fi
  • Link to Metageek Eye P.A.

Ekahau Site Survey

  • Swiss Army knife of Wi-Fi (for more listen to CTS069, CTS009)
    • Site Survey tool (Design, validation, troubleshooting)
    • Wi-Fi scanner
    • Spectrum Analyzer
    • Complete solution meeting the needs of Wi-Fi Engineers
    • Updated on a regular basis
    • Take advantage of the Wi-Fi community to improve the tool (#ESSRequest)
    • Reference in terms of Wi-Fi design and site survey tool today
  • Looks way way way better than AirMagnet
  • Complete set of features
    • 3D Wi-Fi design
    • Reporting and Reporting customization
    • Spectrum Analyzer
    • macOS version (beta)
  • Link to Ekahau Site Survey

Metageek InSSIDer Office

  • Wireless network scanner
  • See what channels are used by other networks
  • RSSI
  • Data rates
  • Protocol
  • Plug in WiSpy dBx for Chanalyzer lite
  • Link To Metageek InSSIDer Office

Savvius Omnipeek

  • Heavy Duty Network Analyzer
    • Use to troubleshoot Wi-Fi networks
  • Capture packets and provide insight on the quality of the network (more than just Wi-Fi)
  • Ability to drill down into the packets
  • Ability to use multiple adapters to captures on multiple channels to analyzer things like roaming behaviours
  • Can be overwhelming at first but very powerful
  • Link to website
  • Video from WLPC2016

CTS 066: Spectrum Analysis with Joel Crane

Joel Crane is our special guest on CTS and he has a lot of knowledge bombs on spectrum analysis. Be sure to listen to this episode.

Interference. The invisible killer of your spectrum. It creates a terrible user experience and your network is to blame for it. Spectrum analysis is how you’re going to identify what is kicking your Wi-Fi to the side.

I’ve used this process to find issues the users are experiencing. Often times the fault is placed on the WLAN but it is either done unintentionally or on purpose. You will usually find out that there is a misbehaving device or a consumer level hardware causing issues with the WLAN.

In this episode, Rowell and François ask Joel Crane questions about what spectrum analysis is and why is it useful.

Spectrum Analysis with Joel Crane

  • Detecting, identifying, and locating non-WiFi interference
  • Gauging co-channel/adjacent interference
  • Who uses it
  • Cool stuff to know about
  • The troubleshooting process
  • Duty cycle vs. utilization
  • Real-time FFT vs Swept-Tuned
