Recently, the Samsung Galaxy S4 mobile phone has repeatedly exposed the problem of not being able to connect to WIFI. In fact, this problem does not only occur on Samsung mobile phones, but also many mobile phones. So why can't mobile phones connect to WIFI? How to make WIFI normal? Now let's explore.
First, make sure your router is working properly. You can use other mobile phones or digital products to connect to the WIFI signal. If you can connect and surf the Internet normally, the router can generally work normally.
Then make sure that the mobile phone with WIFI problems does not have the option to turn off the network in hibernation mode:
Many children's shoes said that their mobile phones would be disconnected or unable to receive messages from the background chat software after a period of time, mostly because they inadvertently or manually turned on their mobile phones to hibernate and turn off the network.
After making sure that everything above is normal, you should find the reason from your router.
1: First, there is a common problem. Many routers sometimes fall into an endless loop of connections, that is, they constantly acquire IP addresses and connect, but they just can't connect. At this time, let's try the universal repair method - restart. After powering down the router completely, turn on the router again after about ten minutes. This restart mode can solve most router problems on one hand.
2: Check whether there are too many WIFI connection devices. If too many digital devices are connected to a router's WIFI, the router will be under great pressure. It is easy to cause IP conflicts and fail to connect. The current office environment of Xiao Bian is like this. Every colleague has several digital devices, all of which rely on the WIFI connection of a router in the company. It is easy for the device to fail to connect to WIFI. This problem can be solved by setting a static IP address for each device connected through WIFI.
3: Try to change the authentication type of the router. Don't feel numb when you hear the words "change the authentication type". The so-called authentication type here is just an option on the router settings.
If you are lazy enough, you should still be in the "Automatic" state for the above authentication type. In fact, it is better to choose the more secure "WPA2-PSK" type here. For the sake of security, the following encryption algorithm should also choose "AES".
4: If none of the above methods can make your mobile phone connect to WIFI normally, it is likely that the router's firmware is incompatible with your mobile phone. At this time, you can choose to upgrade the router's firmware. Different brands of router firmware may have different upgrade methods. However, there are upgrade methods on the upgrade page or on the Internet. Follow the instructions to upgrade.
5: If none of the above methods can realize WIFI connection, it is likely that your phone's ROM has a problem. You can also try to use a more perfect ROM to solve the problem.
After the above operations, the problem that the mobile phone cannot connect to WIFI should be solved. Enjoy the freedom brought by wireless network!
