Wifi Analyzer Android app helps you identify optimal channels for your wireless router to improve speed


I recently switched to T-mobile and upgraded our router to the T-mobile CellSpot (an ASUS dual-band TM-AC1900 router). When setting up this router, I didn’t want to use the default channels. I wanted to select the optimal channels that my wireless router would use on the 2.4Ghz and 5Ghz bands (not all of our devices support the less congested 5Ghz band). Using the Android app called Wifi Analyzer by farproc, I was able to easily see which channels were the most congested. The analyzer provides a graph of the available channels and displays the detectable wireless networks within your vicinity that are using those channels. It also provides graphs of the signal strength of those networks over time, suggests channel ratings (the more stars a channel has the better the channel, although this is affected by the channel you are currently using), provides a list view of all the detectable wireless networks with their signal strengths, provides a WiFi signal meter of individual networks, and gives you a list view of all devices connected to your wireless network under “LAN neighbors”. After using the app to determine your optimal channel(s), you’ll need to log into your router’s web interface, click on the Wireless or WiFi settings, then select the appropriate channel(s). Wifi Analyzer is a free app for all Android devices running Android 2.3 or later and is available through Google Play.

    Wi-fi environments that look like that are one reason I’m glad I live out in the boonies 🙂

      Me too!

        *Sigh* Yes, that is indeed my 2.4Ghz WiFi environment. What’s a Gadgeteer to do? Well, I’ve been slowly upgrading my devices and moving them to the 5Ghz band (my house is a moderate size, so this works) where I am the sole occupant of channel 36 – so, I’ve made lemonade from lemons! 🙂

          I’m stuck in the city too, but yours looks congestion free compared to mine, I have about 25, and that’s on a corner lot! 😉 Chicago sucks!!!!! I’m moving everything I can to 5G. I will say Bluetooth works fine in the 2.4GHz band.

            @David – I don’t envy you. Yep, 5GHz is the place to be! 🙂

    Has anyone found a similar iOS app?

    • Kathleen Chapman July 23, 2015, 8:22 am

      @Mark – I’ve looked around the Apple App Store and found one called WiPry that required an accessory to work like Wifi Analyzer. Otherwise, I couldn’t find one the doesn’t require an accessory, but I may have missed something…

      Well, WiFi Analyzer used to be an iOS App, back in iOS 4 days… but they got banned from the Apple App Store for accessing the wifi stack directly. It then lived on for a while as a jailbreak App, until iOS 5/6 killed any access to wifi data with any real value.

    Been using this for years, has been a staple in my toolbox for tradeshows to deconflict WAPs on the floor, but comes in handy on a regular basis.

    Love being able to snapshot before and after for clients.

    My only gripe is the lack of a pro version.

    Rob Tillotson…multiply the above by a factor of ten on a trade show floor. No lie. Almost all on default channels, screaming at each other. The WAPS get overloaded just processing all the handshakes.
