How to boost Wi-Fi signal on your smartphone

How to boost Wi-Fi signal on your smartphone

If you notice that your Wi-Fi is consuming a lot more battery than it usually does, or you always appear to be connected, but the internet isn't exactly lightning fast, then you might be suffering from a poor Wi-Fi connection. Here's our guide for how to improve the Wi-Fi signal on your Android and iOS smartphones.

Check how far you are from the router

Without even installing an app, it is always a good idea to check how close (or far) you are from your router. In case the speed issues occur only when you are some distance away from the router, it is always a good idea to sit a bit closer. If that is not possible, you may be required to physically move the router to a better location.

If the issues remain even after you are relatively close to the router, it is always advisable to restart it once. 

Learn which Wi-Fi access point is the best

Short of turning the router off and on again, which should always be your first option when suffering from a poor Wi-Fi connection, another way is using the Wi-Fi analyzer app. Firstly, it provides the best channel to use for your particular network. Without going into detail, it allows you to optimize the network and means you don't have to be a technical whizz-kid to do so. 

Secondly, it assesses which network in the area has the most stable connection, which often isn't the one to which your phone connects by default. Lastly, it offers easy access to network information such as your IP address, network gateway, DNS, etc. It's not essential, but useful for power-users.

If you are using an iPhone, an alternative app to do this called Network Analyzer.

Check if your phone case is blocking signal

Using a case with your phone? If yes, you might want to check if one of the causes for poor Wi-Fi (and cellular) connectivity is tied to the case. It is a known fact that many phone cases actually make your Wi-Fi signal worse, especially if they contain metal. 

To see if your case is affecting your Wi-Fi signal, do an Ookla speed test with the case off, then, in the same location, put the case back on and perform the test again.

If you see a difference when using your case you may want to look at alternatives. You can also perform the same test using Ookla's official speed test app. However, the app asks for a wild number of permissions, so we recommend uninstalling it as soon as you have concluded your test.

Make sure your router in the perfect spot

Another trick that can greatly improve the Wi-Fi connection at home is the optimization of the router's location. Often, it is placed right next to the phone or cable outlet, but this is rarely the best for your connection.  There are several apps that help you optimize the position of your router. However, most of the instructions are too technical to be carried out by a layman.

The best recourse, therefore, is to get in touch with your ISP, who will have all the necessary tools to position your router at the best possible location inside your home. Ideally, this should be done by the ISP on the day of installation. 

In case you have a large home spread across multiple floors, it is also recommended that you take a look at Wi-Fi Mesh routers.  

Use the 5 GHz band for Wi-Fi connections

Most Android smartphones (and routers) of today support the 5GHz frequency band. While setting up your router, chances are high your ISP technician created two separate Wi-Fi networks to choose from. Most routers name the 5 GHz networks by suffixing the term 5G at the end of the SSID. 

If you think you are on a slow 2.4Ghz network, it is always a good idea to switch to the 5 GHz band where there's much more free space on the spectrum. There are 23 channels of 20 MHz each on the 5 GHz frequency, which is much more than the 14 channels offered on 2.4 GHz. Because the channels don't overlap, you're likely to get a better signal on your Wi-Fi when connected to a 5Ghz network.

Note that a 5Ghz network has a much lower range compared to 2.4Ghz. You may see a significant drop in speeds if you are connected to a 5Ghz network, but you are physically far away from the router. In such cases, it is better to switch to the "slower" 2.4 GHz band. 

Update your radio or firmware

If you're receiving OTA updates from your carrier or manufacturer, then this probably doesn't apply to you, but if you are running custom ROMs, you may find yourself occasionally needing to manually update the radio on your Android. As an example, here's how to update the bootloader and radio on the Nexus 5. You should also make sure you're on the latest version of Android to ensure the best performance. To check this, go to Settings > About > Software updates.

Tell your phone to avoid poor connections (Android 6.0 Marshmallow or older)

Note: This step is no longer an option on modern Android smartphones.

In the Android Settings menu, there is a nice little option that tells your phone to avoid poor Wi-Fi connections, meaning that while it is scanning for available networks, it will actually avoid trying to connect to those with poor signals. This will save you a lot in terms of power and frustration. Just go to Settings > Wi-Fi and tap the overflow menu button, and then Advanced. Here you will see the checkbox to avoid poor connections.

    Alas, there's no 'Avoid Poor Connections' option on my Samsung Galaxy S4 from AT&T.

    Android should learn to switch better between WLAN networks.
    I for example have internet over cable but our only cable connection is in the cellar and I have my room in the roof (2nd floor, with ground floor in-between) and I have another WLAN router at my room at the roof and whenever I am running somewhere in my house my phone pretty much ALWAYS has the wrong Router with 0 to 1 bars of reception.
    Android should get a WLAN priority list which includes which one can be used interchangeably along with when to switch.

    I tried some apps and did not work because those app only shows full signal of wifi connection but speed not getting higher.

    Anyone have trusted and secured tool for this?

    Umm I tried to download MCPE 1.13 beta apk (I cant wait to see foxes)
    And my internet connection is fine on my ASUS Windows 10 laptop, but on my S5 it is very struggling. he file has 90 MB and I can't download it.
    Can't find any "Wi-Fi band" or Avoid poor internet connections in my Wifi settings (Android 6.0).

    This is just an amazing technique and it really works. Thanks for sharing this blog.

    Use a broadband modem / router with an extender (especially if your dwelling is multi-level, your Wi-Fi is on 2nd Floor and your extender is on the 1st Floor). Set your smartphone and or tablet up to switch from Wi-Fi 2 extender (depending on what Floor you are on). An extender is great for boosting the Wi-Fi signal to your smart TV (or other smart device).

    My problem is that I get crappy reception no matter where I go with my Z5. Every one else's phone, laptops, tablets, etc work fine but mine is always struggling or even saying not connected to the internet when everything else works fine. Does anyone know how to address this?

  • Sorin Apr 5, 2018 Link to comment

    For advanced users, a great way is to install a new firmware, such as DD-WRT. This greatly improves the performance of the router, including signal strength.

    Just a warning about all the "speed test" apps in the Play Store: most are incredibly inconsistent. My ISP uses Ookla on its PC interface, and the Ookla Android app seems to generate the same results - other apps are measuring who knows what, but it ain't that.

    there are numerous ways to improve your WiFi signal, but the final result depends heavily on your environment.

    some tips that may work:

    1. try amplifier -- it can be expensive as specialized directional antenna, or cheap as a soda can.

    2. change channel settings -- the 2.4Ghz WiFi(802.11 b/g/n) only has 3 non-overlapping channels, set your channel to one of 1/6/11 will help reduce the chance of overlapping channels.

    3. regularly scan your environment -- in scan result, you will see how many networks are around you, and the signal strength, channels they running etc. Then you can avoid running a similar network, and find a relatively *clean* environment

    these tips sounds a bit *geeky*, but there are a lot of tools available to ease the processing. For example, WiFi Manager , an Android App, is able to do the scanning, and show result in an intuitive graphic way

      According to my research, 5 gig doesn't have as good a range as 2.8 (apparently), so this can be a factor in which you choose.

  • Preston Odenbrett Apr 16, 2017 Link to comment

    Change your Wi-Fi frequency band to 5 GHz - I do not see this option in an Android Sony z3 or z5- Or at least I can't seem to find it on the Wifi menu choices. No advanced menu? Please help as we do LIVE broadcast for our church in a week area and we need better singles from mobile. Thanks

    which app can help me to boost android hotspot wifi signals?

  • Laurie Henson Jun 17, 2016 Link to comment

    Um, I'm curious how to utilize a metal bowl or tin can. The pic doesn't look like it's set up as a receiver. Or maybe just having the bowl close works?? Is there a certain way to place the bowl and phone or do they have to touch. Because there's no mention of attachment of wires or tin foil etc. Please respond cause I'm curious if it works. This phone frustrstes me with its weak grip on the signal. I don't care if I look like I'm alien crazed. Ya baby! :0
