ANANDTECHI ,

Which wifi card do you have in your computer? What is the error message you receive when trying to install the driver? Are you trying to install the correct driver for the wifi? Did you recently update to Windows 8?  Below are a couple of knowledge Base links that may offer some help in resolving the issue.

ANANDTECHI ,

Below is information that will hopefully get your wifi working in Windows 8.

Wireless Network Issues

Resetting the modem and your router can help fix the network connection in some cases. This helps create a new connection to your Internet service provider (ISP). When you do this, everyone that is connected to your Wi-Fi network will be temporarily disconnected.
The steps you take to reset the modem and router can vary, but here are the general steps:
  1. Unplug the power cable for the router from the wall.
  2. Unplug the power cable for the modem from the wall.

    Some modems have a backup battery. So if you unplug the modem and lights stay on, remove the battery from the modem.
  3. Wait at least 30 seconds or so.

    If you had to remove the battery from the modem, put it back in.
  4. Plug the modem back into the wall. The lights on the modem will blink. Wait for them to stop blinking.
  5. Plug your router back into the wall.

    Wait a few minutes for the modem and router to fully power on. You can usually tell when they’re ready by looking at the status lights on the two devices.
  6. On your PC, try to connect to the Wi-Fi network again.
Note

Some modems have a built-in router, so you’ll only need to unplug that.

To run these networking commands in a command prompt window

  1. Do one of the following, depending on which version of Windows your PC is running:
  • In Windows 7, select Start, type cmd in the search box, right-click cmd in the list, select Run as administrator, and then select Yes.
  • In Windows 8.1, select the Start  button, start typing cmd, right-click Command Prompt in the list, select Run as Administrator, and then select Yes.
  • At the command prompt, run the following commands in the listed order and then check to see if that fixes your connection problem:
  • Type netsh winsock reset and press Enter.
  • Type netsh int ip reset and press Enter.
  • Type ipconfig /release and press Enter.
  • Type ipconfig /renew and press Enter.
  • Type ipconfig /flushdns and press Enter.

Here are some things to check and try with your router if you’re at home and having trouble getting connected.
  • If you’re not seeing the network name, sign in to your router and check to see if it’s set to broadcast the network name.
  1. Connect your PC to your router using an Ethernet cable.
  2. Open your web browser and type the IP address for your wireless router. (For example, 192.168.1.1 or 172.16.0.0—check the documentation for your router to find the default IP address.)
  3. Sign in with your user name and password, then make sure an option labeled Enable SSID Broadcast, Wireless SSID broadcast, or something similar is turned on. This setting is often on a Wireless Settings page.
  • Check to see if your Wi-Fi network uses Media Access Control (MAC) address filtering for security. If it does, you’ll need to add the MAC address for your PC to the access list on your router before you can connect.

To find the MAC address for your PC

  1. Do one of the following, depending on which version of Windows your PC is running:
  • In Windows 7, select Start, type cmd in the search box, right-click cmd in the list, select Run as administrator, and then select Yes.
  • In Windows 8.1, select the Start  button, start typing cmd, right-click Command Prompt in the list, select Run as Administrator, and then select Yes.
  • At the command prompt, type ipconfig /all.

    Write down the address that appears next to Physical Address for your wireless network adapter. This is the address you’ll need to add to the access list on your router.

To add the MAC address to the access list on your router

  1. Open your web browser and type the IP address for your wireless router. (For example, 192.168.1.1 or 172.16.0.0—check the documentation for your router to find the default IP address.)
  2. Sign in with your user name and password, then look for a setting that says MAC Address Filter or something similar.
  3. Add the MAC address you wrote down for your PC to the access list and save your changes.
On your PC, try to connect to the Wi-Fi network again.

ANANDTECHI,

Go to Control panel-> network and sharing-> advanced settings.

Is the wifi adapter disabled? Is there an icon on the wifi adapter? Right click and enable it. You can Uninstall the driver to the wireless adapter, reboot and then reinstall the driver. It could be that your router has channel set as 'auto'. So all you need to do is to set up channel Manually to a number (between 1-8) and your pc will recognize your wifi. (8.1 has a problem with channels > 8) . Let me know if this resolves the issue.
