Messed up command prompt and device manager. Now laptop doesn't detect any internet.

I tried to share my laptop's lan to my mobile using a Youtube video. I changed some options in the device manager and also did something in command prompt. I don't know what did I do but now my laptop doesn't detect either lan or mobile hotspot. I can give the video's link if you can help.https://youtu.be/x1WkOVMQXjs

Greetings!

Welcome to the HP Support Community. This is a great place to get support, find answers and tips to your technical queries. I have reviewed your post and I understand, the Wi-Fi is not working.

Don’t worry, I’m here to help you resolve this issue.

Let's try these steps -

Step 1 Network Troubleshooter - 

1) In the search box, type and open "Troubleshooter".

2) Click on "Network and Internet".

3) Click on "Internet Connections".

Step 2 Run Network commands - 

1) In the search box on the taskbar, type Command prompt, press and hold (or right-click) Command prompt, and then select Run as administrator > Yes.

2) 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.

Step 3 Re-install the Network Adapter - 

1) In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.

2) In Device Manager, select Network adapters > the network adapter name.

3) Right-click on the network adapter, and then select Uninstall device > Delete the driver software for this device check box > Uninstall.

4) Restart the computer.

If the issue still persists, try a system restore as this will put the computer back to a state when it worked fine -

1) Shutdown the computer.

2) Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears.

3) Press F11 once for System Recovery.

4) Choose the Keyboard Layout.

5) Click on Troubleshoot.

6) Go to Recovery Manager and click on System Restore.

7) Choose a Restore point or a Restore date when the computer was working fine.

😎 Click on OK to initialize the System Restore.

Hope this helps!

Let me know how that goes.
