Windows 10: Unable to connect to wifi without a ethernet cable

Hi, I am currently using a lenovo ideapad 320s. Recently, after updating to windows 21H1, my wifi keeps disconnecting at random times. When this happens, the wifi options will disappear. This has been getting worst recently, and now my wifi does not work at all. The intel network adapter is showing code 10 unable to start and it says the device does not exist. How do i fix this?

Wifi not connecting without Ethernet cable


Basically what happened before: After updating to Windows 10, my computer was not showing any network options. (The icon says "Not connected - No connections are available) Going into Control Panel/Network and Internet/Network Connections, it then says "Local Area Connection Network cable unplugged". I ran diagnostics and it said to plug in the ethernet cable to the network adaptor. So my wifi connection will not work with my laptop unless directly connected to by the ethernet cable. Wifi works fine with phones, ipods/ipads, and another laptop that was also updated to windows 10/a desktop still using windows 8.

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.
