Why does the mobile phone WiFi show that it is connected and drops as soon as it goes online?

After receiving the wireless router, of course, you need to set up the wireless router.

Connect the ** line (relatively thin) to the cat's line port (** interface is small), the cat separates a network cable to connect the router's WAN (blue) port, and then find a short network cable, one end is connected to the computer, one end is connected to the router 1234 any interface, if you don't have a cat at home before buying a router, you can also access the Internet, then pull out the previous network cable plugged into the computer at the WAN (blue) port of the router, and then find a short network cable (if you buy a router online, the merchant will generally send a network cable.) It doesn't take long, only use it when setting up the router), and then connect one end to the computer and one end to the router 1234 any interface.

Then configure your computer.

Set the local connection IP address on the computer to "Automatically obtain IP address" as shown below.

Then set up the router to surf the Internet.

In the following page, select the correct way to access the Internet (using ADSL dial-up as an example).

Select "ADSL Dialing" as the Internet access method, enter the account name and password in the broadband connection, and click "OK". The broadband connection account number at home is: Password:

AABCCDD sets the wireless password as: 87654321 Then the correct setting should be as shown in Figure 3 below

Try to see if your phone can access the Internet.

After the settings are complete, the router will automatically jump to the system status page, where you can view the status of the router's WAN port.

If the connection status is "connected" and the IP address has been obtained, then turn on the Wi-Fi of the mobile phone, find the router signal, then enter the password, and click to connect to surf the Internet.

This should be an unstable wifi network.

If the password is correct, then there are only two possibilities if the mobile phone is disconnected from the wifi:

One is that there are too many devices connected to this wifi, resulting in limited wifi connection, in this case, you can only wait to try to connect;

The second is that there is a problem with the wifi network itself, you can choose to ignore this wifi first, then restart the phone, re-search the wifi account and enter the password to connect, if it still doesn't work, restore the factory settings of the wireless router, reconfigure the wireless router, and then connect the wifi to try.

The network quality is not good, just like the mobile phone is sometimes easy to disconnect, but the signal is full, the router also has this problem, now there are many small portable routers, those all use the built-in simple antenna, the signal is not guaranteed, you must use the router with an external 8 decibel antenna.

Because the network connection is unstable, you can reconnect, or turn off the wifi and turn it on again, and sometimes my phone is the same.

It may be that the computer network is unstable and there is no Internet, so check the router.

1. If your WiFi router suddenly can't access the Internet, you can first power off the WiFi router and the cat and restart it, and don't press the reset button. If you still can't access the Internet after restarting, it may be that the broadband line is faulty and you need to report to the operator for repair.

2. If you can't access the Internet because you press the reset button, you need to reconfigure the WiFi router to access the Internet.

3. If you can't access the Internet, maybe the WiFi owner has done MAC address filtering (commonly known as blocking), or the network you are rubbing against is faulty, so you can't access the Internet.

Linking wifi is just saying that you are connected to the router, it may be that the router is not connected to the Internet or has limitations.

There are many reasons for the disconnection, so let's do a two-step simple try:

1. Check whether the computer network cable of the shared wifi is plugged in and whether the network speed is powerful.

2. Try restarting the Wi-Fi on your phone.

If the wifi is still unstable, try further processing:

1. Upgrade the wireless network card driver of the computer.

If the driver is too old, even if it is successfully turned on, the signal may not be good, which will affect the Internet experience.

2. Turn off the ARP firewall of your computer.

The firewall of some security software turns off the wireless process, and you need to turn off the LAN protection.

3. Modify the sleep settings of your computer or mobile phone.

If your computer or phone is set to sleep on a scheduled basis, it will be disconnected from the internet when you use it, and you need to modify the sleep settings in your power plan.

The software is installed on the computer, the mobile phone is connected, and the network cannot be connected after a minute. The wifi display is full, there is no drop, and the mobile phone just can't go to the network.

Possible reasons and solutions for mobile phones not connecting to wifi networks:

1.First of all, check whether the wireless router is working normally, you can use other mobile phones or digital products to connect to the wifi signal, if you can connect and surf the Internet normally, then generally this router can work normally.

2.The phone is turned on to sleep and the network is turned off.

Check whether the phone has the option to turn off the network in the dormant state, the phone will be disconnected after a period of time or cannot receive the background chat software, the possible reason is that the phone is turned on the function of turning off the network by mistake.

3.If you use the router for a long time, the router may freeze its death. Just restart your wireless router.

4.The type of certification is not suitable. Try to change the authentication type of the router, it is better to choose the secure "WPA2-PSK" type mode, and the following encryption algorithm is better to choose "AES".

5.The network settings of the mobile phone or router are abnormal. Consider restoring your router factory settings and cellular network settings.

Hello dear Samsung users:

Based on your description, it is recommended that you:

1.Turn your phone and wireless devices on and off again.

2.Check to see if it's too far away from your wireless router or if there's interference.

3.If possible, this is the case with a change to another router or a wireless connection attempt.

4.Back up your phone's data (book, SMS, multiple files, etc.), restore factory settings to troubleshoot system and software failures.

If the problem persists, we recommend that you take your phone to the nearest Samsung service center for testing.

Comments, suggestions, complaints, please click:

Change the IP address of the computer to dynamic. Or assign another static IP address.

Specific method: Look at the management address on the sign at the bottom of the router, for example, then you can set this address to the computer: (the last number is between 110-200 just write one).

After excluding the network and wifi signal, it is a mobile phone problem, and my previous mobile phone is also like this, and it will not be disconnected if you change your mobile phone, and it is no problem after restoring the factory settings and formatting the mobile phone in a rage, I hope to adopt thank you.
