An unresponsive WiFi connection is not a strange occurrence. It is actually quite a common sight with Android devices.
Most times, it can be solved by switching turning the WiFi connection off for a few minutes and then turning it back on.
This article is here to tell you what to do when the basic “Turn Off/On” does not work.
This can be due to a number of problems. The good news is, you do not have to rush your phone down to the nearest smartphone repairs store.
The more popular WiFi connectivity issues will be discussed here and the solutions will be provided. You do not have to pay to get your phone fixed. By following the steps in this article, you can do it yourself.
PROBLEM 1: ANDROID DEVICE IS UNABLE TO SCAN WIFI NETWORK
This is a very common problem with Android devices. A lot of factors can be responsible for this but the good news is, you can resolve most of these by yourself.
Here are possible reasons for your device being unable to scan a WiFi network:
Difference In WiFi Frequency Band
The average user of Android devices might not be privy to this information but, depending on the mobile device, there are different frequency bands for WiFi.
WiFi standards also differ and three of the most popular standards are 802.11a/b/g, 802.11ac and 802.11n.
802.11a/b/g works with the 2.4GHz frequency band although, on other devices, the frequency band could be 5GHz.
Some 802.11ac and 802.11n standards use a 5GHz frequency band.
Therefore, if your smartphone is equipped with a 2.4 GHz WiFi chip, it will be unable to detect a WiFi network that operates on the 5GHz frequency band.
So, if your device’s WiFi chip is incompatible with the frequency band, it will not be able to detect the signal.
The Network Is Hidden
Sometimes, wireless networks are set with their SSID hidden. This is usually a security measure although some devices are automatically set this way.
Therefore, if you want to connect to the network, you will have to supply the network password and SSID.
If this is the reason why your device cannot detect the WiFi signal, all you have to do is access the WiFi menu and use the “Add Network” option. You will still have to supply the SSID and network password but that is the only requirement.
However, you must ensure that the SSID you provide is the right one otherwise, the connection will still not be established.
You’re Connecting To An Ad-Hoc Network
Wireless routers are used to set up Ad Hoc WiFi networks. This is very easy to set up on PC platforms. All you have to do is use the WiFi chip.
However, Android devices do not have a default support setting for ad-hoc wireless networks.
There are two ways to solve this issue.
You can use a wireless router to create the WiFi network or you can simply enable your Android smartphone’s ad-hoc network support.
To do this, you will need to have root access on your phone and you will concurrently have to deal with the wpa_supplicant file.
The second measure here is really stressful and I will not recommend you use it. Unless, of course, you are ready to go through the stress.
PROBLEM 2: WIFI CONNECTION IS REALLY SLOW
Everybody must have encountered this problem at some point. It could be with the wireless network set up at home or it could be at public hotspots but whatever the case may be, slow wireless connections are not a strange occurrence.
Here are possible reasons why WiFi networks can keep disconnecting.
Old WiFi routers are usually range dependent. This usually means that your browsing speed will be determined by how close your router is to your Android device.
Ensure that there is no physical obstruction between your router and the device connected to the wireless network.
Also, there are some places in your house that could serve as WiFi dead spots. The name Is pretty much self-explanatory. In this location, browsing speed is usually slow.
You can find out possible dead spots in your home through the use of an app called WiFi Solver. The app analyzes the positioning of the WiFi router and other objects in your house. It uses this to detect WiFi dead spots and also to recommend a new browsing spot for you.
Check Other Devices
Sometimes, the reason you cannot connect to the WiFi network is simple. Another device is connected.
Some WiFi routers are set to allow a limited number of users at a time. If your router has such a restrictive setting activated, you will not be able to connect your device to the network if the stipulated number is already full.
Also, if there are a lot of devices connected to the network, it will lead to faster consumption of resources and this ultimately leads to a slower WiFi network.
If you discover that your WiFi router has more than the required amount of devices connected to it, turn it off and adjust the connectivity settings.
PROBLEM 3: WI-FI NETWORK FREQUENTLY DISCONNECTS
There are a lot of factors that can be responsible for this.
WiFi Sleep Policy
WiFi sleep policy dictates what happens to your WiFi router when your Android device is not in use.
If this setting is activated, you will regularly experience disconnection issues.
You can solve this by simply adjusting the system settings. All you have to do is access the Advanced Section of your Wireless Networks screen.
From there, set the tab title “Keep WiFi on during Sleep” to Always Active. This setting will ensure that your WiFi connection does not go off even when you smartphone is in sleep mode.
For users of an upgraded Android version, you can adjust the setting via the WiFi screen in the Settings app.
