Windows 10: Bluescreen error while connecting to new Wifi networks

I recently purchased a Lenovo Legion 5 Pro. AMD Ryzen 6800H, 32Gb RAM, RTX3070. It runs Windows 11.Had no issues while setting up the laptop. After the first windows update, suddenly I started getting a ndis.sys blue screen error System thread exception not handled error whenever I tried to connect to a new Wi-Fi network. I tried rolling back the updates and reinstalling the latest drivers from Lenovo's website for my Wifi card.However I was running into the same error. The only thing that seemed to resolve it was changing the 5G network adapter value in device manager to 802.11 a or 802.1

:)

 

Is it possible to set up a new manual wifi connection from the command line?

I'm trying to work out a solution to set up ad-hock wifi connections in Windows 8.1 based on the suggestions in a post on Micsrosoft's answers site. Is there any way to do the first few steps:

• go to "Network and Sharing Center"
  
• click "Set up a new connection or network"
  
• double click "Manually connect to a wireless network"
  
• enter the SSID of the ad-hoc network (as shown by "netsh wlan show networks") into the "Network name" field
  
• configure security settings accordingly
  
• uncheck "Start this connection automatically" (important)
  

...without using the windows dialogs?

 

How to connect to an existing wifi network?

As you suggested, I tried disabling the ethernet adapter and that caused wi-fi to connect, so the desktop wifi does work. Also, I accessed the router and changed the wireless network name (to wfCHS). Thanks!

However many problems are still unresolved:

My laptop behaves just as I want it to. Assuming the router has wifi turned on and the laptop has an ethernet connection, connection to the internet is by ethernet (no private network name), and the wi-fi connection is to my private network "wfCHS", but with no connection to the internet. (If I disconnect the ethernet cable, then wfCHS becomes connected to the internet and stays that way even if I reconnect the cable.) A directory listing shows both laptop and desktop under "Network". Great!

Things are rather different with the desktop. With Ethernet disabled, the desktop shows a wi-fi connection to the internet. Under Settings > Status it's called "wfCHS" but under Network Connections it's called wfCHS2. If I then re-enable the ethernet connection, the wifi connection stays enabled for a minute or two, then disconnects. Further, the ethernet connection is given the name wfCHS2 under both Status and Network Connections.

Why does the desktop give an (unwanted) name to the ethernet connection while the laptop doesn't?

Why does the desktop disconnect its wi-fi connection a minute or so after the ethernet connection is enabled, while the laptop doesn't?

Why does the desktop give two different names to the wifi connection, depending on whether it's viewed under Status or Network Connections, while the laptop doesn't?

Why does the laptop show the desktop under Network, while the desktop shows only itself?

Things are so convoluted that I'd be happy to start over. I've had the desktop "forget" the wi-fi connection as you suggested, then re-established it, but this hasn't helped. Can the ethernet connection also be "forgotten"?

Really appreciate the help you've given so far!

 

unable to connect to wifi network

Hi Alexander,

Reading through your post, we see that you have run a lot of troubleshooting steps to resolve your WiFi network connection issue. There ares some other steps though that you may still do to resolve it.

Please check Fix network connection issues in Windows 10.

To site some:

• On the first item about Things to try first, you will see basic troubleshooting steps. Included in this topic is a suggestion to contact your Internet Service Provider which will be able to guide you in checking connection with your router.
• Running the Network troubleshooter. This topic also includes applying network commands that may be able to help you. Please try the other network commands and check if it works.
• Uninstalling the network adapter driver and restart. You may try if you had a
  recent update.
• If you are running running Windows 10 Version 1607 or later you may also try
  Using network reset.

If you have tried all of the above and the connection still fails, you may try some other steps listed below:

• Change channel width for your network adapter.
  • Press Windows Key + S and enter type network. Chose
    Network and Sharing Center from the list of results.
  • When Network and Sharing Center opens, click the Change adapter settings.
  • Locate your wireless adapter and right click it. Choose Properties from the menu.
  • When Properties window opens, navigate to Advanced tab.
  • Select the 802.11 channel width and change the value. Some users have reported that changing the value to
    20 MHz has fixed the issue for them, but you might have to use a different value.
  • Click OK to save the changes.

• Disable IPv6 on your computer and router.
  • Open Network and Sharing Center.
  • Find the Connections section and click your current connection.
  • Connection status window will open. Click the Properties button.
  • Find Internet Protocol Version 6 (TCP /IPv6) and uncheck it.
  • Click OK button to save the changes.
  • Restart your computer in order to apply the changes.
  • If the problem still persists, you might have to disable IPv6 on your router. Disabling IPv6 on your router is a complicated process, and it’s different for every type of router, so before you do that, check the your router’s instruction manual.

• Make sure that your adapter and router are using the same security type.
  • Open Network and Sharing Center and click the Manage wireless networks.
  • Find your wireless network, right click it and choose Properties.
  • Go to Security tab, find Security type section and select the
    same security type that your router is using. You might have to try several different security types before you pick the right one.
  • lick OK to save changes.

• Add the connection manually.
  • Open Network and Sharing Center.
  • Click Set up a new connection or network.
  • Choose Manually connect to a wireless network and click
    Next.
  • Enter the requested information such as network name, security key and security type.
  • Click Next to finish the process.
  • After you’ve created a new network connection, everything should be working without any problems.
    
  • If the issue persists, try changing the security type of your new network.
