wifi driver vanished

Hi harishsk3033,

It appears that the wireless adapter/card on your laptop gone missing. Have you made any changes or installed any updates on your laptop prior to the issue? If yes, what were those changes or updates?

Basically, since the wireless adapter/card no longer appears in Device Manager, then it implies that the device is no longer detected. Downloading its drivers will not do any help. The wireless adapter/card has to be detected first before you can install
its driver.

As a workaround, I suggest performing the following steps to try to re-detect the wireless adapter/card:

• Reboot the laptop
  • To insure that the laptop is properly rebooted, I recommend to shut it down first, before starting it up again.
• Scan for hardware changes
  1. Open Device Manager.
  2. Right-click the Network adapters category, and click
     Scan for hardware changes.
  3. Check if the wireless card appears. If yes, then right-click it, and click
     Update driver software.
  4. Follow the on-screen instructions.
• Check for Other devices in Device Manager.
  1. Go back to Device Manager and look for Other devices.
  2. If it's there, then expand it.
  3. If the wireless adapter/card is on the list, then right-click it and click
     Update Driver Software.
  4. Follow the on-screen instructions.

If the above steps won't help, then there's a need to unplug and replug the wireless adapter/card on your laptop to have it detected. Please contact your computer manufacturer for proper assistance.

Kindly update this thread with the result so I'll be able to assist you further if needed.

Regards.

laptop can't find wifi but connects with ethernet cable

Please try these troubleshooting steps that may help.

1. Make sure the router SSID broadcast is on.
   
2. Change the wifi channel to see if it resolves the problem.
   
3. Enter the SSID and WPA2 password manually and see if the laptop connects.
   
4. Temporarily turn off the encryption.
   
5. We go into device manager & check updates for wifi drivers, we may need to simply update the driver.
   
6. We go to Settings - Network & Internet - Status - Change Adapter Options, then right-clicked 'Ethernet' and disabled it. We do the same with wifi. Then we (with Ethernet still disabled) enabled wifi. It should re-connect to your wifi after a while.
   
7. We have to disconnect our Ethernet cable from our laptop and follow the steps:
   Start>Control Panel>Network and Sharing Center>Manage Wireless Networks and remove all wireless connections by right click on it and select Remove network from the drop down menu. After doing this, close the windows and scan for the wifi networks.
   Click on the available network and select connect. After a while, we will be asked to give a password for our wifi connection. Type the password and click on connect button. And now will be connected to our wifi network via wireless.
   
8. First is to disconnect the internet cable from the laptop then uninstall/reinstall the wifi adapter.
   Go to Device Manager and uninstall the wifi adapter.
   Once uninstalled, reboot the laptop and it should reinstall the driver automatically.
   After the reboot do try connecting to your wireless network again.
   If all these will not work, do also make sure that the wireless adapter is enabled. Depending the model of your laptop there should be key combinations on how to enable/disable it.
