Measure your WiFi Throughput with Fritz!App WLAN

Depending on where you live, setting up a wireless network may be as easy as plugging in the router and connecting your devices to the network. If you are unlucky, however, you may run into performance issues right away with the default settings.

Maybe reception works fine in one room but not another, or it is not fine at all once you move a couple of steps away from the router.

You find lots of advice online on how to optimize a wireless network. Check used channels and switch to one that is used by the least number of access points in the vicinity. You may also get advice to buy a wireless repeater, or a stronger antenna for the router if that is supported.

Fritz!App WLAN

Fritz!App WLAN is a free application for Android devices that you may use to measure the throughput if WiFi networks.

The application works with all kinds of wireless networks and does not require a Fritz router. It displays information about the wireless network that the Android device is connected to on start. You get a reading of the signal strength right on the start page.

A click on "measure WiFi Throughput" starts a speed test. The app runs the speed test continuously until you hit the stop button. The test highlights the signal strength and the bandwidth utilization.

You can run a baseline test near the wireless router or access point, and then additional tests in other rooms or even outside to test the output and signal strength.

After you ran the first series of tests, you may modify router settings, e.g. the channel or orientation of the antenna to see if it improves the reception. This requires some measuring on your part but helps you determine the best settings for WiFi throughput.

The connect tab assists you in finding the best channel for the signal. It highlights all wireless signals that the device picks up, and displays them on a graph.

You may want to check the channels in all places you require wireless network access as new signals may be picked up in different places.

The app displays the strength of 2.4 GHz and 5 GHz signals; just scroll down on the page to display the chart for 5 GHz networks.

Fritz!App WLAN's connect page lists all wireless networks that the device picked up when you open it. It supports filtering options to display only known/2.4 GHz/5GHz networks and to sort the listing by the reception, name, or average dBm.

The listing may be useful, especially if you have access to multiple networks and need to pick one from the listing. You can connect to any of the listed networks directly from within the application.

The app comes with extra features besides the ones mentioned above. It supports WPS, the scanning of wireless information using QR codes, NFC, and the scanning for home network devices.

Closing Words

Fritz!App WLAN is a handy application for Android devices to test the WiFi throughput and assist users in finding the best access point and settings.

You may find apps like Network Tester for Android, WiFi Analyzer, or TekWiFi for Windows useful as well in that regard.

    Thanks for the tip Martin.

    It is for these kinds of posts that I follow GHacks.

      What’s up with the generic comment, are you a bot?

    Where on the planet is that still in use? I was forced to give up using my RAZRV3 years ago because 2G was phased out by AT&T.

    1. arbuz said on August 20, 2023 at 5:02 pm

      Everywhere 3G has been turned off and you don’t have LTE coverage, and believe me there are many developed countries where this is the case and if it weren’t for 2G you wouldn’t even be able to make a phone call.

      Maybe I missed it, but I don’t believe tha term “2G” is in the article. Perhaps you are referring to “AGM G2”??

    Your website has gone insane.

    When I the post button I then saw my comment posted on a different article page. When I opened this article again, it is here.

      ” Your website has gone insane. ”

      Same here. Has happened several times.

        @Martin P.,

        For over two weeks now,
        I’ve been seeing “Comments” posted by subscribers appearing in different, unrelated articles.
        For the time being,
        it would be better to specify the “article name and URL” at the beginning of the post.

    @tachy a lot of non-phone devices with a sim in them rely on 2G, at least here in europe.
    Usually things reporting usage or errors/alarms on something remote that does not get day to day inspection in person. They are out there in vast numbers doing important work. Reliable, good range. The low datarate is no problem at all in those cases.
    3G is gone or on its last legs everywhere, but this stuff still has too much use to cancel.

    Anyhow, interesting that they would put that in. I can see the point if you suspect a hostile 2G environment (amateur eavesdroppers with laptop, ranging up to professional grade MITM fake towers while “strangely” not getting the stronger crypto voip 4G because it is being jammed, and back down to something as old ‘stingray’ devices fallen into the wrong hands).

    But does this also mean that they have handled and rolled out a fix for that nasty 4G ‘pwn by broadcast’ problem you reported earlier this year? I had 4G disabled due to that, on the off chance that some of the local criminals would buy some cheap chinese gear, download a working exploit and probe every phone in range all over town in the hope of getting into phones of the police.

    >”While most may never be attacked in stingrays, it is still recommended to disable 2G cellular connections, especially since it does not have any downsides.”

    The downside would be losing connectivity. I spend a lot of time way out in the countryside where there’s often no service or almost none. My network allows 2G, and I need it sometimes. I have an option on the phone to disable 2G, I may do that when I’m in the city and I have good 5G connectivity, but not out in the country.

    I would imagine that the stingray exploits, like most of the bad things in this world, are probably things you will run into in the crowded big cities.

    I stopped using it in a mobile (Wi-Fi line) environment, so I’m almost ignorant of the actual situation,
    But the recent reality in Japan makes me realize that “the infrastructure of the web is nothing more than a papier-mâché fiction”.

    It is already beyond the scope of what an individual can do.
    What we should be aware of is the reality that “governments and those in power want to control the world through the Web”, and efforts to counter (resist and prevent) such ambitions are necessary.

    Why do you want people to disable the privacy features? Hmmmmm?

  8. Anonymous said on August 27, 2023 at 2:30 am

    Now You: do you plan to keep the Ads privacy features enabled?

    I’d like to tell you, but apparently if you make a post critical of Google, you get censored. * [Editor: removed, just try to bring your opinion across without attacking anyone]

    You website is still psychotic. Comments attach to random stories.

    @Martin please do fix the comments, it’s completely insane commenting here! :[

  11. ECJ said on August 28, 2023 at 5:37 pm


    The comments are seriously messed up on gHacks now. These comments are mixed with the article at the below URL.

    And comments on other articles are from as far back as 2010.

  12. Naimless said on August 29, 2023 at 12:57 am

    What does this article has anything to do with all the comments on this article? LOL I think this Websuite is ran by ChatGPT. every article is messed up. Some older comments from 2015 shown up in recant articles, LOL

    The picture captioned “Clearing the Android Auto’s cache might resolve the issue” is from Apple Carplay ;)

    How about other things that matter:
    Drop survival?
    Screen toughness?
    Degree of water and dust protection?
