Whatsapp Pinterest

Smartphones are now well established as the main way most of us connect to the internet. It’s a trend that looks irreversible. And it means getting the fastest possible internet speeds on your mobile devices is more important than ever.

But sometimes this doesn’t happen. There might be problems with the way you’ve set up your home router, or with the quirks of public Wi-Fi, or even issues with your carrier.

Let’s take a look at the main reasons why you have slow internet on your phone, and how you can fix them.

There’s a quick way to test. The Wi-Fi icon on your phone’s status bar gives you a rough indication of the signal strength.

  • When the icon is full, you’ve got a strong signal. This suggests your slow internet has a different cause.
  • When it’s empty your signal is weak, and other Wi-Fi devices like your laptop should also be affected. Move closer to your router and your signal strength — and internet speed — should improve.

A weak signal that does improve shows that your router’s position is the problem.

There are so many public Wi-Fi hotspots, and your phone is liable to latch onto one of them at random. It’ll even stay connected after you’ve moved into range of a closer or better one.

    Also, if the WiFi protocol your phone uses is outdated, that will definitely slow your connection down considerably. (Like an older or budget phone may not use the current ac standard)

    Very helpful information, thanks for that.
    I have a Galaxy s7 phone that was running on 5ghz and a Galaxy s7 Edge running on 2.4ghz (same Wifi router and close to equal data usage and Tmobile is the carrier). Well both lines have a 2GB cap before it gets slower. Well the phone using the 5ghz was using A LOT more data and hit the data cap within only a few days, yet the phone using the 2.4ghz did not have this issue. The data usage one the 2nd phone was only around 120MB. So I changed it so that both phones were using the 2.4ghz and it solved the issue.
    I understand that there is range difference and 5ghz is faster, but it using so much more data has baffled me and I cannot seem to find anyone that has also had this issue. So now.i don't know if running my roku tv on 5ghz is a good idea. Anyone have any thoughts on this ? (Oh, internet provider is Spectrum)
