Guide to Fixing Android Wifi Connectivity Issues
* Precautions before troubleshooting Android's Wifi connectivity issues
- Make sure you've activated the Wifi feature on your Android phone.
- Ensure that the Wifi network you want to access is both available and set up on your device.
- Try accessing a different Wifi network to verify.
- Double-check the Wifi password for accuracy.
- If you're still unable to connect to a previously accessed Wifi network, go to Wifi settings. Hold down on the desired Wifi network, select Forget Network, then proceed to reconnect as you would with a new Wifi network. Remember to enter the correct password.
- If you're the network administrator, try restarting the Wifi Modem device and checking network connection ports for any loose cable issues.
1. Connected to Wifi but still no internet access.
- Possible cause: Incorrect static IP address or gateway configuration.
* Troubleshooting steps:
+ Firstly, test with another device, check the network being used to see if there's a loss of connection (e.g., laptop, other wireless devices) to determine if there's a network issue.
+ If the Wifi network is stable, then verify DNS, IP, and Gateway settings on your device by navigating to Settings > Wifi > the connected network.
Step 1: Access the Settings app > Wi-Fi then hold and select the Wifi network you're currently or wish to connect to as shown below.
Step 2: A form will appear for user selection, to troubleshoot Wifi issues on the device, we select the Modify network option.
Then proceed to select Advanced options as shown in the image above. Here we scroll down the options panel and select IP settings to Static.
Step 3: After selecting Static IP, the device screen will display all options to change this Wifi network. We set the IP parameters, Gateway, Netmask, DNS as shown below:
Note: IP Address: Typically 192.169.1.x (you can choose x from 2-254, just avoid IP conflicts with other devices, if this IP is conflicted we won't be able to connect to the Internet despite successfully connecting to Wifi).
· Gateway: 192.168.1.1 (192.168.0.1, 192.168.100.1...)
In this example, Mytour.vn chooses to fill in the reserved IP as 192.168.1.128 to avoid conflicts with IPs that have accessed Wifi networks before.
·
Subnet Mask: 255.255.255.0
·
Primary DNS: 8.8.8.8
·
Secondary DNS: 8.8.4.4 (DNS for accessing facebook)
In some cases, we may skip entering this DNS and still troubleshoot Android Wifi connection issues without internet access.
Then save it and check whether the Android Wifi connection issue has been resolved.
2. Wifi access error due to IP conflict on the phone
- Unlike the issue of being connected to Wifi but still unable to access the internet mentioned above, when encountering an IP conflict on your Android phone while trying to connect to a Wifi network, we won't be able to proceed with Wifi connection anymore. What you need to do at this point is to change the IP address we've set on the Wifi network we're connecting to in order to fix this Android Wifi connectivity issue.
- The solution to resetting the Wifi network's static IP settings is completely similar to method 1 above, you can refer to and follow these steps.
3. Android unable to find wifi network
In most cases, the issue in this scenario is caused by the Wifi network being broadcasted from another mobile device such as a laptop, phone, etc.
* Troubleshooting:
Step 1: First, you need to download the wpa_supplicant file, then extract the zip file and save it to an external memory card with the following address: sdcard/wpa_supplicant.
Note: If you're unable to extract this file on your device, you'll need to download the Rar app for Android here: Download Rar for Android.
Step 2: Next, you need to install the file manager app ES File Explorer for Android (Requires ROOT) to copy the extracted file to the Android device system.
Step 3: When copying the file, turn off wifi on the device, then open the installed ES File Explorer app for Android and copy the wpa_supplicant file saved on the sdcard to the System/bin directory (overwrite - paste and replace) as shown below.
- Then we restart the device and check if the Android wifi network not found issue has been resolved.
4. Intermittent wifi connection, slow internet access
The cause is often due to features, battery-saving apps on your Android device. When running these apps, in standby mode, or locked, they'll automatically manage the Wifi connection process on the device to help save power on the phone.
* Troubleshooting:
Step 1: To troubleshoot, we continue accessing the Settings app > Wi-Fi
Then we tap on the 3-dot icon at the top right corner of the screen as shown above to set up this intermittent Wifi connection issue. Then we continue to select Advanced (Advanced settings).
Step 2: Here we search for the Keep Wi-Fi on during sleep feature as shown below.
And set this feature to Always to ensure stable Wifi network connection even when the device is in sleep mode, locked.
5. Repetitive wifi connection process, Infinite Loop
For example, catching wifi but unable to access the internet, the device repeats the wifi connection process continuously, the device connects to wifi sometimes and sometimes not.
The cause may be due to the Android operating system generating this error: The device receives an IP address, then connects successfully, disconnects, then searches for a new IP address…. This creates a repetitive loop.
* Troubleshooting:
If encountering wifi connection loop errors, users need to reinstall the wifi driver on android using the Wifi Fixer app for Android. Download the app here Wifi Fixer for Android.
- After installation, users need to restart the Wi-Fi router. Then enable the Wifi fixer app for Android. The app will reset Wi-Fi system files and services, helping users connect to the network and obtain an IP address.
- Then swipe down the screen from top to bottom to view the status bar of this app. When the device encounters Wifi network connection issues, we just need to select Reassociate as shown above.
6. Other wifi connection errors
If poor wifi reception is due to external factors, Mytour.vn advises you to add more wifi models or wifi repeaters to increase wifi coverage area quality. Especially with Wifi Modem devices placed too far from device usage locations or obstructed by various walls, affecting signal transmission and Wifi reception on each Android device.
