Since when did you change the password of your Wi-Fi network you are no longer able to surf the Internet? Is your computer can’t connect to the Wi-Fi network despite the proper working of the router? Don’t despair. You are probably dealing with a simple PC configuration problem, or perhaps a router, but there is nothing to worry, as the problem can be solved easily.
To dispel any doubts on the issue, try reading the guide on how to re-enable a wireless network. Unless the problem is hardware in nature, with serious failures to the computer’s network card or router, you should be able to restore your connection and surf the Internet within a few minutes.
Note: The following tutorial is for PC with Windows 10, but the steps can be used for any other version of Windows.
Re-enable wireless networks on Windows
If the Wi-Fi connection works properly on all devices but not on the computer, there is probably something wrong with the Windows settings. Then try entering the control panel and re-enabling the wireless connection from there.
To access the network settings, click on the Start button (the Windows flag located in the lower left corner of the screen) and look for the term connections in the menu that opens. Click on the item View network connections present in the search results and, in the window that opens, find the icon for the wireless connection.
At this point, right-click on the Wi-Fi network icon and select the item Enable from the menu that appears. If everything is spun the right way, within a few seconds Windows will be able to re-enable the wireless network and automatically connect to it.
The automatic connection only works if you have already used the network and you have activated the password storage on the PC in the past. Otherwise, you will have to click on the Wi-Fi icon in the notification area (next to the Windows clock), you will have to select the name of the network from the menu that opens and you will have to type in the connection protection key.
If the procedure described above has not helped you solve your connection problems, try accessing the network and sharing center by looking for it in the classic Windows control panel (which you can retrieve by looking for it in the Start menu).
In the window that opens, select the item troubleshooting at the bottom and choose to check the status of the Internet connections. Windows will analyze the status of the connections saved on the PC and, in case of problems, will fix the situation.
If the network card is disabled or not properly configured, click on the Windows Start button and go to the Device Management panel looking for it in the menu that opens.
A list will appear with all the hardware components on your computer. Then expand the icon for the Network Cards and find out if there is any component with the transparent icon and/or a yellow triangle beside its icon.
If the network card has a transparent icon and/or is marked with a yellow triangle, then that indicates a component is not active or its driver is not working properly. To solve the problem, right-click on the card icon and select the item Enable from the menu that opens.
If the card is already activated and therefore the option to enable it is not available, connect the computer to the Internet via Ethernet cable and try to update the device drivers by right clicking again on its icon and selecting the Update driver software item from the contextual menu.
In the unfortunate event that Windows could not automatically find the network card drivers, follow the instructions in my tutorial on how to update drivers for free and provide to update the software “manually”.
Is the network card active but you still can’t connect to the Internet from your PC? If the problem occurred after changing the Wi-Fi password, try this other procedure: go back to the network and sharing center menu. In the window that opens, click on the name of the wireless connection that is located next to the Connections item (top right), press the Wireless Properties button and type the new Wi-Fi network password in the Security tab of the window that opened. Finally, click OK and Windows should be able to use the network without problems.
