Phone WiFi Slow

Are you facing the phone WiFi slow issue? Sometimes, your smartphone does not receive usable WiFi signals regardless of everything you do. Not always; the issue is not limited to budget smartphones.

This problem can occur on all smartphones equally. Smartphones cram various hardware into tiny frames. Also, the WiFi antenna’s position determines the signal’s strength.

Usually, smartphones connect to the internet through one of the two methods: WiFi or cellular. If you notice your phone’s WiFi is slow, then you can try certain things to fix the problem.

Learn here different ways to resolve the phone WiFi slow issue. Before that, learn what actually affects your internet speed below:

What Actually Affects Your Internet Speed?

Many variables determine whether you are struggling with slow internet speed or not. These variables include:

  • Connection strength
  • Kind of activity
  • Do you have firewalls, VPNs, or proxies enabled?
  • Connection kind: Bluetooth, WiFi, 3G, 4G, or LTE
  • What platform or browser do you use?
  • iOS version
  • iPhone model
  • Are all things slow? Or even one app?

So, there are lots of factors that contribute to reliable WiFi signals on your smartphone. If you are struggling with the issue while staying connected to WiFi, there are some things that you can try.

PS: let’s figure out why my internet is so slow all of a sudden and how to fix the iPhone WiFi not working.

Part 1: How to Resolve the Phone WiFi Slow Issue on Android

Try the solutions listed below if you face the phone WiFi slow issue on your Android smartphone.

1. Resolve Phone WiFi Slow Issue Using a Network Analyzer

Measuring your WiFi network’s strength when your smartphone is getting an unstable WiFi signal. For this, you can try applications, such as NetX Network Tools. This is a reliable utility that can be used for the signal strength of your WiFi.

This lets you check if any other WiFi signal interferes with your WiFi. Plus, the best thing is that this program is available absolutely for free.

Usually, WiFi signals are broadcasted within a narrow band set. Various devices, including microwaves and Bluetooth speakers, emit radio waves at similar frequencies. So, utilities such as NetX work amazingly when you try to gauge the WiFi signal quality.

Modern routers feature dual-band connectivity, such as 2.4GHz and 5GHz bands. Usually, the 2.4GHz frequency is the common one. This band delivers signals over wider regions.

However, you would not get much bandwidth. For example, if you have a Gigabit line in your home, but you would never get more than 150Mbps on 2.4GHz bands.

Also, 5GHz channels deliver more than 500Mbps of bandwidth consistently, but the drawback is that this range is not good. This is because the signal does not go across walls effectively.

Ideally, users should have both of these bands broadcasting having different names. So, they can easily distinguish between the 5GHz and 2.4GHz bands.

Employ NetX to examine if there is another WiFi interference. Also, it can be used for changing the channels as required for every band on the router. Visit to log in to the administration interface of your router.

After that, modify the Control Channel to the one not employed by another WiFi network.

2. Forget the WiFi Network and Log Back In

If resolving the interference has not resolved the problem, forget the WiFi network and begin over.

Visit the settings of your phone and choose the ‘Connections’ tab. After that, click on ‘WiFi’ and long-press on the WiFi network that you are using.

Then, click on ‘Forget network.’ This is going to clear all the saved login credentials. Now, log back in again to your WiFi. Now, check if the phone WiFi slow issue has been fixed.

3. Restart the Router to Fix the Phone WiFi Slow

So, you may have listened to this solution many times before. However, it is a solution that typically works. Sometimes, your router runs out of memory or uses up several CPU cycles.

So, to bring it back to usual, a restart helps a lot. Ideally, users need to turn off their routers and wait for some seconds. Then, they can turn it on.

Depending on the router, it will take some minutes for the network to show back again on the smartphone. Check if the phone WiFi slow issue still persists!

4. Reset Your Network Settings to Fix Phone WiFi Slow Issue

When the above solution does not work for you, resetting your device’s network settings is a good option. This will flush all your saved WiFi networks, paired Bluetooth devices, and mobile data settings.

Basically, you are starting over with the network connectivity. However, users do not need to get rid of the data present on their smartphones to do so.

To do this, visit your device’s settings and go to the menu ‘Reset.’ From there, choose the ‘Reset Network Settings’ option. Press Enter, and then all your network settings will reset.

Now, log back into your WiFi network and check if the phone WiFi slow problem has been successfully resolved.
