Note down the Wi-Fi adapter name and version. The name of the wireless network adapter will be at the top of the Driver tab. [2] X Research Source
- Example of the name of a wireless network card: “Intel Centrino Advanced-N 6235.”
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/07/Reinstall-Wireless-Drivers-Step-7-Version-2.jpg/v4-460px-Reinstall-Wireless-Drivers- Step-7-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/07/Reinstall-Wireless-Drivers-Step-7-Version-2.jpg/ v4-728px-Reinstall-Wireless-Drivers-Step-7-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Navigate to the Wi-Fi card manufacturer’s Support section. This is where you will find driver download links for your device.
- For example, if your wireless card is made by Intel, go to www.intel.com and click “Support.”
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/88/Reinstall-Wireless-Drivers-Step-8-Version-2.jpg/v4-460px-Reinstall-Wireless-Drivers- Step-8-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/88/Reinstall-Wireless-Drivers-Step-8-Version-2.jpg/ v4-728px-Reinstall-Wireless-Drivers-Step-8-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Search by name of the Wi-Fi tag. This is the name that you recorded earlier. Once the Wi-Fi card is located, click the link to go to the product’s website.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d0/Reinstall-Wireless-Drivers-Step-9.jpg/v4-460px-Reinstall-Wireless-Drivers-Step-9. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d0/Reinstall-Wireless-Drivers-Step-9.jpg/v4-728px-Reinstall-Wireless-Drivers-Step- 9.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Download the driver for your version of Windows. You may need to click on a link with something like “Download”, “Software” or “Drivers” to find download links.
- Most organizations provide drivers in “.exe” format, so it’s easy to download and install.
- Save the downloaded file in an easy-to-remember location like the Downloads folder or the desktop.
Uninstall the current driver
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c8/Reinstall-Wireless-Drivers-Step-10.jpg/v4-460px-Reinstall-Wireless-Drivers-Step-10. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c8/Reinstall-Wireless-Drivers-Step-10.jpg/v4-728px-Reinstall-Wireless-Drivers-Step- 10.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Go back to Device Manager and expand the “Network Adapters” list. Now we will proceed to remove the current driver.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c5/Reinstall-Wireless-Drivers-Step-11.jpg/v4-460px-Reinstall-Wireless-Drivers-Step-11. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c5/Reinstall-Wireless-Drivers-Step-11.jpg/v4-728px-Reinstall-Wireless-Drivers-Step- 11.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Right-click the wireless network card under the “Network Adapters” heading and select “Properties”.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f8/Reinstall-Wireless-Drivers-Step-12.jpg/v4-460px-Reinstall-Wireless-Drivers-Step-12. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f8/Reinstall-Wireless-Drivers-Step-12.jpg/v4-728px-Reinstall-Wireless-Drivers-Step- 12.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Go to the “Driver” tab, then click “Uninstall”. A confirmation window will pop up.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/40/Reinstall-Wireless-Drivers-Step-13.jpg/v4-460px-Reinstall-Wireless-Drivers-Step-13. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/40/Reinstall-Wireless-Drivers-Step-13.jpg/v4-728px-Reinstall-Wireless-Drivers-Step- 13.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Click “OK” to confirm. The entry for the wireless network card will disappear from the “Network Adapters” list.
Driver installation
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/46/Reinstall-Wireless-Drivers-Step-14.jpg/v4-460px-Reinstall-Wireless-Drivers-Step-14. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/46/Reinstall-Wireless-Drivers-Step-14.jpg/v4-728px-Reinstall-Wireless-Drivers-Step- 14.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Double-click the .exe file you just downloaded. The system program will install the wireless network drivers. [3] X Research Sources
- If the file ends with “.zip” instead of “.exe”, right-click the file and select “Extract All”. Select a folder to extract the files and click “Extract”. Finally, double-click the .exe file located in the folder you selected.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f1/Reinstall-Wireless-Drivers-Step-15.jpg/v4-460px-Reinstall-Wireless-Drivers-Step-15. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f1/Reinstall-Wireless-Drivers-Step-15.jpg/v4-728px-Reinstall-Wireless-Drivers-Step- 15.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
(If there is no .exe file) Click the “Action” menu at the top of the Device Manager window, then select “Scan for hardware changes”. Device Manager will scan your computer for drivers for the hardware. [4] X Research Sources
- When it finds the driver, Windows will automatically install it. If you want to check if a new driver is installed, expand the list of network adapters and look for the Wi-Fi adapter entry.
- If the driver is not found, the computer will ask you to browse for the folder containing the driver file. Navigate to the folder where you extracted the .zip archive, then click “OK” or “Install”.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d1/Reinstall-Wireless-Drivers-Step-16.jpg/v4-460px-Reinstall-Wireless-Drivers-Step-16. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d1/Reinstall-Wireless-Drivers-Step-16.jpg/v4-728px-Reinstall-Wireless-Drivers-Step- 16.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Follow the on-screen instructions to install the driver. The screen will vary depending on the operating system and wireless network card, but you will usually have to agree to the manufacturer’s terms before proceeding to the “Install” button.
- If the installer asks you to restart your computer after the setup is complete, click “OK” or “Restart Now” when prompted.
Disconnect the LAN wire. To make sure you’re testing the correct connection type, you’ll need to unplug the Ethernet cable from the LAN port on your computer.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/8f/Reinstall-Wireless-Drivers-Step-18.jpg/v4-460px-Reinstall-Wireless-Drivers-Step-18. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/8f/Reinstall-Wireless-Drivers-Step-18.jpg/v4-728px-Reinstall-Wireless-Drivers-Step- 18.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Connect to your Wi-Fi network and go to https://www.wikihow.com . If the problem is indeed the driver, you should now be able to access wikiHow wirelessly.
- Try restarting your computer if it still can’t connect. Then, open Device Manager and run “Scan for new hardware” again.
- If it still doesn’t fix it, the problem may not be with the driver.
Advice
- Setting Windows to update automatically will keep your wireless network driver up to date.
- Many Internet connection problems can be solved by unplugging the power cord behind the router or Wi-Fi access point, and then plugging it back in. This action is to renew the “energy cycle”.
- Try moving the computer really close to the Wi-Fi router/access point.
