How to solve wifi problem in windows 10

Run network commands

Try running these network commands to manually reset the TCP/IP stack, release and renew the IP address, and flush and reset the DNS client resolver cache:

1. In the search box on the taskbar, type Command prompt. The Command Prompt button will appear. To the right of it, 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 select Enter.
   • Type netsh int ip reset and select Enter.
   • Type ipconfig /release and select Enter.
   • Type ipconfig /renew and select Enter.
   • Type ipconfig /flushdns and select Enter.

Uninstall the network adapter driver and restart

If the previous steps didn’t work, try to uninstall the network adapter driver, and then restart your computer. Windows will automatically install the latest driver. Consider this approach if your network connection stopped working properly after a recent update.

Before uninstalling, make sure you have drivers available as a backup. Visit the PC manufacturer’s website and download the latest network adapter driver from there. If your PC can’t connect to the internet, you’ll need to download a driver on a different PC and save it to a USB flash drive so you can install the driver on your PC. You’ll need to know the PC manufacturer and model name or number.

1. In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.
2. Expand Network adapters, and locate the network adapter for your device.
3. Select the network adapter, and then select Uninstall device > the Delete the driver software for this device check box > Uninstall.
4. After uninstalling the driver, select the Start  button > Power  > Restart.After your PC restarts, Windows will automatically look for and install the network adapter driver. Check to see if that fixes your connection problem. If Windows doesn’t automatically install a driver, try to install the backup driver you saved before uninstalling.

Check if your network adapter is compatible with the latest Windows Update

If you lost your network connection immediately after upgrading or updating Windows 10, it’s possible that the current driver for your network adapter was designed for a previous version of Windows. To check, try temporarily uninstalling the recent Windows Update:

1. Select the Start  button, then select Settings  > Update & Security> Windows Update  > View update history > Uninstall updates.
2. Select the most recent update, then select Uninstall.

If uninstalling the most recent update restores your network connection, check to see if an updated driver is available:

1. In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.
2. Expand Network adapters, and locate the network adapter for your device.
3. Select the network adapter, select Update driver > Search automatically for updated driver software, and then follow the instructions.
4. After installing the updated driver, select the Start  button > Power  > Restart if you’re asked to restart, and see if that fixes the connection issue.

If Windows can’t find a new driver for your network adapter, visit the PC manufacturer’s website and download the latest network adapter driver from there. You’ll need to know the PC manufacturer and model name or number.

Do one of the following:

• If you couldn’t download and install a newer network adapter driver, hide the update that’s causing you to lose your network connection. To learn how to hide updates, see Hide Windows Updates or driver updates.
• If you could successfully install updated drivers for your network adapter, then reinstall the latest updates. To do this, select the Start  button, then select Settings  > Update & Security> Windows Update  > Check for updates.

Use network reset

Using network reset should be the last step you try. Consider using it if the steps above don’t help to get you connected.

This can help solve connection problems you might have after upgrading from a previous version of Windows to Windows 10. It can also help to fix the problem where you can connect to the internet, but can’t connect to shared network drives. Network reset removes any network adapters you have installed and the settings for them. After your PC restarts, any network adapters are reinstalled, and the settings for them are set to the defaults.

Note: To use network reset, your PC must be running Windows 10 Version 1607 or later. To see which version of Windows 10 your device is currently running, select the Start button, then select Settings > System > About.

1. Select the Start  button, then select Settings  > Network & Internet  > Status > Network reset.
   Open Network & Internet Status settings
2. On the Network reset screen, select Reset now > Yes to confirm.Wait for your PC to restart, and see if that fixes the problem.

Notes: 

• After using network reset, you might need to reinstall and set up other networking software you might be using, such as VPN client software or virtual switches from Hyper‑V (if you’re using that or other network virtualization software).
• Network reset might set each one of your known network connections to a public network profile. In a public network profile, your PC is not discoverable to other PCs and devices on the network, which can help make your PC more secure. However, if your PC is part of a homegroup or used for file or printer sharing, you’ll need to make your PC discoverable again by setting it to use a private network profile. To do this, select the Start  button, then select Settings  > Network & Internet  > Wi-Fi . On the Wi-Fi screen, select Manage known networks > the network connection you want to change > Properties. Under Network profile, select Private.
