Why WLAN keeps not connecting?

Generally, there are the following situations:

1. Unable to connect to the network due to incorrect entry of wireless network password

Under normal circumstances, we use a wireless router to connect to the Internet, so when you can't connect to the wireless network, you must first carefully check the connection password of the wireless network you entered, which is very important, because if the password you enter is wrong, then it must be impossible to connect to the wireless network, so you must be very aware of this.

<>2.When you enter the wrong wireless password, in this case, you need to find the password of the wireless network, if necessary, you can restore the factory settings of the wireless router, and then reset the wireless password of the router, so that we can successfully connect to the wireless network.

2. The DHCP server of the router is not enabled and the network cannot be connected

If you are sure that your wireless network password is entered correctly, but you still can't successfully connect to the network, then we need to check the configuration of the wireless router, if the DHCP server of the wireless router is not opened, then we will definitely not be able to successfully obtain the corresponding IP address, and we will not be able to connect to the network.

2.If you are sure that your wireless router DHCP server is turned on, but you still can't connect to the network, then it may be because the address pool of the wireless router is full, of course, this situation is relatively rare, unless a wireless router is connected to a lot of devices, in this case, it is recommended that you restart the router directly and try to connect to the network.

3. The wireless network cannot be connected to the network due to the wrong configuration of the wireless network

In addition to the network configuration problem of the router, there is also a common problem, that is, there is a problem with our wireless network configuration. If we use a wireless router to surf the Internet, then the connection must automatically obtain the IP address, as well as the DNS server address, if there is a problem with the configuration, then change it as soon as possible.

2.Of course, there is also a situation, that is, the router has turned on MAC address filtering, what does it mean? That is, every wireless device has a unique fixed MAC address, if the router settings filter this MAC address, then the device cannot obtain the IP, which means that it cannot connect to the wireless network;

In this case, unless it is your own wireless router, you can reconfigure the change, if it is rubbing other people's wireless network, unfortunately, there is no way to connect to the network in this case.

Finally we can check the cause with Windows Network Diagnostics

For users of Windows 7 system and above versions, if you really can't find the reason why you can't connect to the wireless network, then you can open the Windows network diagnostics to check, if the system is a problem that can be automatically solved, then it also saves us a lot of energy and time, which is very good.

<> above are the common reasons why the wireless network cannot be connected, and the above methods can generally solve everyone's confusion about surfing the Internet.

Sometimes, when you use your mobile phone to connect to a wireless network, you will not be able to connect to the Wi-Fi network on your mobile phone. You can turn on the airplane mode of your phone first, and then turn it off after a while, and see if it has any effect. Or just restart your phone and see if you can connect.

Also check to see if there's a problem with your router.

Under normal circumstances, we use a wireless router to connect to the Internet, and when we encounter a wireless network that cannot be connected, we must first carefully check whether the connection password of the wireless network we entered is correct.

If you can't connect to Wi-Fi for a long time, you can check the indicator light of the router to see if the display is normal, and at the same time check whether the network cable is falling off, and you can also restart the router.

If you have tried a variety of methods and can't connect, then you can call ** to the customer service of the network cable to ask if there is a network failure, if there is no problem with the network, it is likely that the hardware of the mobile phone is faulty.

System Version:

Generally, if there is a network problem, you can perform the following operations:

1. Pull down the notification bar from the top of the phone screen, and then switch to "Switch".

2. You can see that "WLAN" and "Data" have been turned on, and then touch the gray "Airplane Mode Morning".

3. The "airplane mode" will soon become highlighted, and the "WLAN" and "data" have become gray.

4. Then, turn off the "Airplane Mode" again, and then turn on "Wi-Fi" or "Data" again, and the basic limb can go online.

5. If it still doesn't work, try to turn off the wifi first and then turn it back on. Because the mobile phone is not in the case of a change in the network environment, it may be that some network information has not been updated synchronously.

6. If it still doesn't work, check the router channel used, and set the router wireless channel to a commonly used channel, such as 6 and 9.

7. If the above still does not solve the problem, it is recommended to restart the mobile phone and wireless router to see.
