how to reinstall windows 11 networking after wifi fails to connect and all other options have been tried and failed

Question

My Windows 11 laptop cannot connect to this network, my Windows 10 laptop which is 5 feet further from the router connects just fine to the same network. The Roku V connects just fine and my phone connects by scanning QR code. Both HP laptops have been running fine for about a year since I got this router. Suddenly I get this cannot connect message.  I have tried everything spent maybe two weeks on the problem. Finally narrowed the problem down.  “netsh int ip reset log.txt” does not complete because of a reset and authorization failure. I think the network stack is corrupted. 

How can I solve this problem, a laptop without WIFI is not very useful?

 

Answer 1

Given that other options have failed and netsh int ip reset cannot complete, use the following deeper recovery steps for Windows 11 networking.

1. Uninstall and reinstall the network adapter driver
   1. Select Search on the taskbar, type device manager, and select Device Manager.
   2. Expand Network adapters and locate the wireless adapter.
   3. Right‑click the adapter and select Uninstall device.
   4. Check Attempt to remove the driver for this device and select Uninstall.
   5. Select Start > Power > Restart.
   6. After restart, Windows will automatically look for and install the network adapter driver. Test Wi‑Fi. If Windows does not install a driver, install the latest Wi‑Fi driver downloaded from the PC or adapter manufacturer (using another device and USB drive if needed).
2. If the adapter is missing or disabled
   1. Open Device Manager again and expand Network adapters.
   2. If the wireless adapter shows a warning icon, open Properties and check the error code, then update the driver from the manufacturer’s site.
   3. If the adapter is present but disabled, right‑click it and select Enable device.
   4. If the adapter is not listed at all, manually install the correct driver from the device manufacturer.
3. Run full TCP/IP and DNS reset commands (as admin)
   1. Select Search on the taskbar, type Command Prompt.
   2. Right‑click Command Prompt > Run as administrator > Yes.
   3. Run these commands in order, pressing Enter after each:
      • netsh winsock reset
      • netsh int ip reset
      • ipconfig /release
      • ipconfig /renew
      • ipconfig /flushdns
   4. Restart the PC and test Wi‑Fi again.
4. Use Network reset (last resort before OS repair)
   1. Select Start, type settings, then open Settings > Network & internet.
   2. Select Advanced network settings > Network reset.
   3. Select Reset now > Yes to confirm.
   4. The PC restarts; Windows removes all network adapters, reinstalls them, and resets all network settings to defaults. Reconnect to Wi‑Fi and reconfigure any VPN or virtual switches afterward.

If Wi‑Fi still cannot connect after driver reinstall and Network reset, the remaining options are:

• Install a fresh, known‑good driver from the manufacturer (matching the exact adapter model and Windows 11 version).
• As a broader repair, perform a Windows reset with Keep my files, which reinstalls Windows while preserving personal data but removes apps and settings.

Ethernet connection is fine and not relevant

Answer 4

Hi,

So you connect to the Wi-Fi network but don't have internet access, is that correct?

What is the model of your HP laptop?

Have you tried connecting via cable to see if you have a network connection normally?

Thanks
