Most new laptops are equipped with all the components necessary to go online wirelessly to account for the increasing popularity of Wi-Fi Internet.

If you find that you are not able to connect to any wireless networks on a laptop, take a few basic troubleshooting steps on your own before having the laptop serviced.

In all likelihood, you will be able to restore your laptop's wireless functionality and be browsing Wi-Fi Internet in no time.

Enable the wireless card by pressing the radio button, typically located near the top of the keyboard.

Press the radio button until a light illuminates indicating that your wireless card has been enabled and is ready to go online wirelessly.

Test your connectivity once again; if there is still no wireless access, it is time to check for a possible issue with your wireless card.


Navigate to the computer's device manager by opening the "Start" menu and either clicking "Device Manager" from the "Control Panel" window or right-clicking "My Computer," clicking "Properties," and choosing "Device Manager" from the "Hardware" tab, depending on what version of operating system you use.


Look for the wireless card in the Device Manager by clicking the "+" next to "Network Adapters." If you see any item labeled "Wireless Card" or "Wireless Controller," check to see if it has a "?," "X," "!" placed over the name; if it does, you will need to update the software drivers for the wireless card. Contact the manufacturer of the computer for assistance.

Attempt to connect a wireless network other than your home network. Make sure you connect to a wireless network that you are legally allowed to use, such as a free public Wi-Fi hotspot, and that you are not illegally connecting to someone else's wireless network.

If you can connect to other Wi-Fi networks, the problem is likely isolated to your home network and you will need to troubleshoot that.

If you are still can't connect to any Wi-Fi networks after following the steps above, you may need to have the laptop serviced or have its wireless card replaced.

Internet not connecting?


May be your Ethernet Controller is not installed. To confirm this, go to "Control Panel", click "System" from there look out for "Device Manager", click it, check "Network Adapter" to confirm if your Ethernet controller is installed or not. You might also see "Others", in the "Device manager" where you will find only components of your Laptop that are not installed with a yellow exclamation mark.

If you have confirmed that your network adapter is not installed, then you wil have to install the drivers.

Please give me feedback.

Take care.

I had to reinstall windows xp. Now I cannot connect to the internet.


Make sure the driver of the Ethernet Card on your computer is installed. You check it under Device Manager

Right-click My Computer > Properties > Hardware Tab > Device Manager > Network Adapters (click the +). If you see Other Devices with yellow exclamations like Ethernet Controller, that's it. You need to run the Motherboard CD to automatically install the ethernet driver.
