Step 2: The Network Connection Details dialog box will be displayed on the screen, where you find and save the IPv4 default address.

Note: The above steps cannot be performed without using a wired network connection. In case if you know the router’s IP address, you can use it to perform the next steps, otherwise try the addresses 10.1.1.1, 192.168.0.1, 192.168.1.1, 192.168.2.1. Or you can use another computer or laptop connected to the Internet to check this information.

Step 3: Open any browser on your computer and enter the IPv4 address there.

Step 6: If you are trying to use WPA or WPA2, make sure both the network card and the wifi router support this protocol. If you’re having trouble using WPA or WPA2, try reconfiguring the router to use WEP instead and check if you can connect.
If it is possible to connect to the Internet via WEP, it is very likely that the network hardware requires a firmware upgrade. Otherwise, you should contact the hardware/router manufacturer directly for assistance.

Then display a message that detects one or more wireless networks, click on it to display more options. The Available Wireless Networks window will display a list of all the networks in range. Select the access point you want to connect to, and try accessing the Internet to check if the error persists.

Method 7: Reset TCP / IP stack

One of the main Windows components of an Internet connection is the TCP/IP stack that can be corrupted or damaged. In this case just reset TCP/IP stack using Netshell utility (Netsh) to fix the problem.
Step 1: Open Command Prompt under Admin by entering cmd in the Search box on the Start Menu, on the list of search results right-click it and select Run as Administrator.

– The Internet Protocol Version 4 (TCP/IP v4) dialog box opens. You choose “Use the following IP address”, in the “IP address” box, enter the router’s default number: 192.168.1.1. This sequence of numbers has the form 192.168.1.x so to avoid conflicts you can change it to 192.168.1.2, 192.168.1.3…
– Under “Subnet mask” enter the number 255.255.255.0 — the code used for the home network. At “Gateway” enter the default router IP address as above: 192.168.1.1
