This phenomenon is very common when using Windows. Usually, you will choose to restart your computer, turn off router or swift, or turn off Airplane mode. The above methods usually take a long time, but the effect is not high. So I share some ways to fix the problem cannot access the network even if the icon is connected.

The following tips will help you solve the following two problems:

  • The computer connects Wifi successfully, but not to the network, but the phone can still be caught.
  • Limited Computer Limited.

The cause and how to fix it:

  • Due to misconfiguration in wifi router or swift network

You have to keep in mind that preconfigured networks allow you to connect Wifi to the network, so do not go into a configuration reset. If the reset has to call the PABX requires reconfiguration. If you are using wifi client devices such as TP-links, or other popular modems … and have IT knowledge, see if your computer has MAC address blocking. Turn off the computer, turn on DHCP on the router, then proceed to a network connection.

  • Due to network configuration on computer equipment

This is the most common case, and if you are an IT person, this is a must know skill. Restarting the machine, turning the router on or off, or turning off Airplane mode is only to refresh the computer’s IP address. It is possible that the IP address conflicts with the computer that we have connected to wifi but not to the network.

Each device on the wifi has its own IPv4 address, which is not allowed to overlap. And if the duplicate will be able to access the network even if the connection is successful. To proceed with the release and issue of the new IP address, do the following:

Step 3: Enter the ipconfig / release command. This will release the IP address for all connectors. Look at the picture below, will see the whole thing is Media disconnected.

 Step 4: Enter ipconfig / registerdns to refresh the entire DHCP and DNS configuration

 Step 5: Continue typing ipconfig / renew. This command is used to issue new IP addresses on the computer.
