Hello Android fans! Today’s troubleshooting episode addresses one common issue on many Android devices: slow wifi issue. If you have slow wifi problem on your Huawei P20 Pro, learn how to deal with it below.
How to fix Huawei P20 Pro slow wifi issue
Fixing slow wifi issue requires doing a set of troubleshooting steps to narrow down the causes. Follow the steps below to know what you can do.
Check wifi connection speed
If you are administrator of your wifi network, you should have an idea how fast your wifi internet connection should be. Most Internet Service Providers (ISP) are expected to provide about 80% of their advertised connection speed. For instance, if you are paying for an advertised 100Mbps connection speed, you can expect to get a minimum of 80Mbps at most times. Anything below that can be considered poor service and must be addressed by your ISP. So, the first troubleshooting step that you want to do in this case is to check whether or not you have an issue with your ISP. To do that, follow the steps below.
- Disconnect all devices from your wifi except one that you want to use to check your internet connection speed. This is to ensure that no other connected devices may be using your wifi to stream videos or download large files.
- If you’re using a computer, go to sites like speedtest.net or fast.com. If you are on your Huawei P20 Pro, you can either use your web browser to visit the same sites, or download any speedtest app.
- Run a speedtest for at least 3 times.
- Compute the average of the three download speed test results. If the speedtest results are way below your expected connection speed, there must be a problem on your ISP side. In this case, you should contact them so they can help you troubleshoot further.
On the other hand, if wifi internet speed is normal or falls within 80% of advertised speed, but apps on your Huawei P20 Pro appears slow, there must be other reasons for it. You should continue troubleshooting your phone.
Power cycle network devices
In any network trouble, it’s always a good idea to begin troubleshooting by refreshing all equipment involved. Make sure to restart your modem/router and all other devices. For your modem/router, you want to unplug it from the wall outlet for at least 10 seconds to refresh its system. For portable devices, a normal restart should do.
One of the first troubleshooting steps that you can try on your Huawei P20 Pro is by restarting it. Here’s how to do it:
- Press the Power key for a few seconds.
- From the menu select Power Off and tap OK.
- Wait for about 5 seconds.
- Turn on device again with the Power button.
Forget wifi network
When it comes to wifi troubleshooting, it’s also a good idea to forget the wifi network. You can go under Settings > Wireless & networks > Wi-Fi and then choose your network to do so. This will disconnect the phone from said network so it will ask you again for the password the next time you reconnect.
Try static IP [optional]
Sometimes, changing the IP type of a wifi network connection to static instead of the default dynamic option can also fix problems. This troubleshooting step requires checking the fixed or static IP segment of your router ahead of time since you’ll need to enter the correct static IP. Consult your router manual if you have no idea how to do this.
Here’s how it’s done:
- Connect to your wifi network.
- Go to Settings > Wireless & networks > Wi-Fi.
- Tap and hold on your wifi network.
- Tap Modify network option.
- Select Advanced options.
- Tap IP settings.
- Tap Static.
- Enter the following information in the page that shows up: static IP address, gateway, network prefix length, and domain name.
- Once you’ve saved all the correct information, tap on Save to confirm the changes.
Toggle automatic use of mobile data
Your Huawei P20 Pro is designed to switch to mobile data by default if wifi signal is weak or non-existent. Sometimes, this feature may become buggy or inefficient for some reason. To see if this is the one that’s causing the wifi issue at hand, you can try to turn it off. Here’s how:
- Turn on mobile data.
- Open Settings app.
- Tap Wi-Fi+
- Tap Wireless & networks.
- Tap Wi-Fi.
- Tap Wi-Fi+
- Press the indicator next to Wi-Fi+ to turn the function on or off.
Reset network settings
This is one of the important troubleshooting steps when dealing with network issues including wifi troubles. Doing this step resets all wireless network configurations back to default, including wifi, mobile data, and bluetooth.
- Open Settings app.
- Tap System.
- Tap Reset.
- Tap Network settings reset.
- Tap Network settings reset to confirm.
Disconnecting your SIM card from your device often brings benefits especially when it comes to fixing network issues. That’s because doing so forces the device to clear old or current configuration and replaces it with a new and possibly new one. Network problems may sometimes stem from network modifications on your carrier-level.
Before you remove the SIM card from your Huawei P20 Pro, be sure to turn the device off to avoid possible data corruption. Once you’ve removed the SIM card, wait for a few seconds before re-inserting it. Again, be sure that your phone is off before you insert the card.
Clear cache partition
Sometimes, a corrupted system cache can lead to problems. To make sure that Android is using a good system cache, which is located in the cache partition, follow the steps below.
- Turn your Huawei P20 Pro off by holding down the Power key and then tapping Power off.
- Once it has shut down, hold down the Power and Volume up keys together until you see the Huawei logo.
- Release the Power key, but keep holding the Volume up key until you see EMUI on screen.
- Use Volume down to highlight Wipe cache partition.
- Press Power key to select Wipe cache partition.
- When it’s done use Volume up to highlight Reboot system now and the Power key to select it.
Check for bad app
Sometimes, a third party app may interfere with Android, resulting to bugs. To see if a downloaded app is causing a problem, try to boot the device to safe mode.
- Turn off the phone.
- Turn on the phone.
- Once the Huawei logo screen is displayed, press the Volume Down button repeatedly until you see Safe Mode at the bottom of the screen. If you are unsuccessful, repeat Steps 1-3 until you get it right.
Remember, safe mode blocks third party or downloaded apps. If wifi connection speed becomes normal or improves significantly, that’s a sign that one of the downloaded apps may be hogging the bandwidth. We’ve seen this behavior on devices with bad apps or malware. In other cases, poor or inefficiently coded apps can cause problems as well. To identify which of your downloaded apps is causing the problem:
- Exit safe mode by restarting your device.
- Check for the problem.
- If the problem returns, boot to safe mode again.
- Uninstall an app. Start with the most recently downloaded one.
- After each removal, restart your device and see whether removing it solved the problem.
- Repeat steps 1-4 until you’ve identified the culprit.
- After you remove the app that’s causing the problem, you can reinstall the other apps that you removed.
Factory reset your your Huawei P20 Pro
To resolve any unknown phone bug that prevents sending of texts, you want to factory reset your device. Be sure to back all personal data ahead of time.
- Turn off the phone.
- Then turn the phone while holding down the following key combination: Power Button Volume Up Button
- Hold down the buttons until the Huawei logo disappears from the display and the screen turns black.
- You can now release the buttons.
- This will now display the boot menu after a moment.
- Go to the entry “Wipe Cache Factory Reset ” with the volume keys then select it using the power key
- Reboot the phone once the process has completed
