My friends who use Android often come to me with problems related to
device’s Wi-Fi connection
. Moreover, it is not an isolated problem. There are all sorts of things they bring up.
I usually fix their problems after a few tries, but today while troubleshooting on my device, I realized that it can happen to anyone — even a single person. my fake on Guiding Tech. Therefore, we will discuss the four most common Wi-Fi problems on Android and see the possible causes and solutions for them.
Android cannot scan for Wi-Fi networks
Reason
There can be two reasons why your Android cannot automatically scan for networks. The first reason could be that the network you are trying to connect to may be Ad-Hoc in nature. Since most Android phones are not configured to work on Ad-Hoc networks but on access points, they do not scan them.
The second reason could be that the Wi-Fi network you are trying to connect to may be hidden for security reasons.
Solution
By default, Android does not support Ad-Hoc Wi-Fi networks, but many developers have patched the wpa_supplicant file on Android to make them work. If you do a quick Google search you should be able to find if a fix is available for your device but the fix can only be done on rooted phones. Also, don’t forget to backup your original wpa_supplicant file if your phone goes into confiscation or boot loop.
If the problem is with the hidden network, you can try adding it manually. In Android’s Wi-Fi settings, open the menu and tap to add a network manually. You must enter the correct SSID, authentication type, and password to connect to the network. If both logins are correct, the Android phone should be able to connect to the network.
Wi-Fi keeps disconnecting
Reason
The most obvious reason for the problem could be the Wi-Fi Sleep Policy which will disconnect your Wi-Fi every time your Android goes to sleep to save battery.
Solution
To manage Wi-Fi Sleep Policy, open Advanced Wi-Fi Settings on Android and tap the option Turn on Wi-Fi while sleeping. This, check the option Always to enjoy an uninterrupted connection, but you’ll have to make up for it with battery life.
If you’re using any third-party app to save battery, check if it’s controlling your Wi-Fi and other radio services and configure it accordingly.
Get IP Address Infinite Loop
Reason
I don’t know the exact reason behind this, but it could be a bug in Android. I have seen many people have this problem and it is annoying that the problem is not fixed even after restarting the device.
Solution
First of all, you have to restart your Wi-Fi router and see if that helps. Many people say that resetting the phone to its factory state but that is not a proper solution. Wi-Fi Fixer is a great Android app that can help you here. The app resets your Wi-Fi system files (just like when you reinstall your Wi-Fi drivers in Windows or you turn off and on your Wi-Fi adapter) and services, and helps you connect to the network and get the IP address.
If you know the range of IP addresses your router is broadcasting from, you can configure your Android to use a static IP address while connecting to the network.
Unable to connect to the Internet using Wi-Fi
reason
There could be several reasons as to why you cannot connect to the internet even when you are connected to Wi-Fi. The reasons could be:
- The router does not broadcast internet services.
- The IP address or port is incorrect.
- Problem with DNS settings.
Solutions
You can use another device to check if the router is really broadcasting the internet. Alternatively, you can manually configure the IP address, gateway, and DNS to connect as they may have issues with DHCP.
Conclusion
These are most of the Android problems that users may face on their devices and possible solutions that users can try to fix the problem. I don’t guarantee that you will fix the problem but it’s a good start anyway. And most solutions should actually work.
