How can Windows 10 fix Wi Fi connection issues in Windows?

Resolve network issues in Windows
If you are unable to get email, browse the web or stream music, it is likely that you are not connected to your network and cannot access the Internet. To solve this problem, you can try the following actions.

Windows 10

First, try the following actions
First, try performing the following actions to help you solve the connection issue or narrow down the scope of the problem.

Ensure that WLAN is turned on. Select the right side of the taskbar

The “No Internet Connection” icon ensures that Wi Fi is turned on. If not, please select it to open it. Additionally, please ensure that “Airplane Mode” is turned off.

Afterwards, please check if the Wi Fi networks you know and trust are displayed in the network list. If so, select “Wi Fi network” and try connecting to that network. If it displays “Connected” below the network name, select “Disconnect”, wait for a moment, and then select “Connect” again.
Try connecting to the network using different frequency bands. Many consumer Wi Fi routers broadcast in two different network frequency bands: 2.4 GHz and 5 GHz. They will appear as separate networks in the list of available Wi Fi networks. If your list of available Wi Fi networks includes both 2.4 GHz and 5 GHz networks, please try connecting to other networks.
Please ensure that the physical WLAN switch on the laptop is turned on. (When it is in the open state, the indicator light usually lights up.)
Run the network troubleshooting program. Network troubleshooting helps diagnose and solve common connection problems.
Run network troubleshooting

Select the Start button>Settings>Network&Internet>Status.
Under “Change network settings”, select “Network troubleshooting”.
Follow the steps in the troubleshooting section to see if the problem has been fixed.
Restart the modem and wireless router. This helps (ISPs) create new connections to internet service providers.

When performing this operation, everyone connected to the Wi Fi network will temporarily disconnect. The steps required to restart the modem and router may vary, but the following are general steps. (Note: If you have a cable modem/Wi Fi router combination device, you only need to follow the steps of a single device.)
Unplug the power cord of the router from the power source.
Unplug the power cord of the modem from the power source.

Some modems have backup batteries. If you unplug the modem and the light remains on, please remove the battery from the modem.
Wait for at least 30 seconds.

If you must remove the battery from the modem, please re-enter it.
Reconnect the modem to the power supply. The light on the modem will flash. Wait for them to stop flashing.
Reconnect the router to the power supply.

Wait a few minutes for the modem and router to be fully powered on. Usually, you can determine whether two devices are ready by checking the status indicator lights on them.
On the computer, try reconnecting.

Narrowing down the root cause of the problem
Connection issues may be caused by various factors, such as issues with websites, devices, Wi Fi routers, modems, or internet service providers (ISPs). Please try performing the following steps to narrow down the root cause of the problem.

If the “Wi Fi Connected” icon appears on the right side of the taskbar, please visit other websites. If the website is opened, there may be a problem with the specific website. If you are unable to connect to another website, please proceed to the next step.
Try connecting to the same network on another laptop or phone. If it can be connected, the root cause of the problem may be caused by the device. If you are unable to connect to the network on any device, please proceed to the next step.
Check if there are any issues with the connection of the Wi Fi router. Use ping test to perform this operation.
In the search box on the taskbar, type “Command Prompt”. The Command Prompt button will be displayed. On its right side, select “Run as administrator”>”Yes”.
At the command prompt, type ipconfig and then select “Enter”. Find the name of the Wi Fi network in the results, and then look for the IP address listed next to the “default gateway” of that Wi Fi network. If necessary, please note down the address. For example: 192.168.1. one
At the prompt, type pingand then select “Enter”. For example, type ping 192.168.1.1 and select Enter. The results should be as follows:

Reply from 192.168.1.1: Byte=32 Time=5ms TTL=64

Reply from 192.168.1.1: Byte=32 Time=5ms TTL=64

Reply from 192.168.1.1: Byte=32 Time=5ms TTL=64

Reply from 192.168.1.1: Byte=32 Time=5ms TTL=64

Ping statistics for 192.168.1.1: Sent=4, Received=4, Lost=0 (0% Lost), Milli’s average round-trip time: Minimum=4ms, Maximum=5ms, Average=4ms. If you see such results and receive a reply, you have a connection to the Wi Fi router, so there may be a problem with your modem or ISP. If you can check for any service interruptions, please contact your ISP or conduct online checks on other devices.
If the ping test results indicate that you have not received a response from the router, please try connecting the computer directly to the modem using an Ethernet cable (if possible). If you can connect to the internet using an Ethernet cable, it will confirm that the connection issue is caused by the Wi Fi router. Please ensure that you have installed the latest firmware and review the documentation for your router.

Run network commands
Try running these network commands to manually reset the TCP/IP stack, release and renew IP addresses, and refresh and reset the DNS client parser cache:

In the search box on the taskbar, type “Command Prompt”. The Command Prompt button will be displayed. On its right side, select “Run as administrator”>”Yes”.
At the command prompt, run the following commands in the listed order and check if this solves the connection issue:
Type netsh winsock reset and select Enter.
Type netsh int ip reset and select Enter.
Type ipconfig/release, then select “Enter”.
Type ipconfig/renew and then select “Enter”.
Type ipconfig/flushdns and select “Enter”.

Uninstall the network adapter driver and restart
If the above steps do not work, try uninstalling the network adapter driver and then restarting the computer. Windows will automatically install the latest drivers. If the network connection stops working properly after the recent update, please consider using this method.
Before uninstalling, make sure to back up available drivers. Visit the computer manufacturer’s website and download the latest network adapter driver from it. If your computer cannot connect to the internet, you need to download the driver on another computer and save it to a USB flash drive so that you can install the driver on the computer. You need to know the computer manufacturer and model name or model number.

In the search box on the taskbar, type “Device Manager” and then select “Device Manager” from the results list.
Expand “Network Adapters” and locate the network adapter for your device.
Select the network adapter, then select “Uninstall device”>”Remove driver software for this device” checkbox,>”Uninstall”.
After uninstalling the driver, select the Start button>Power>Restart.
After restarting the computer, Windows will automatically find and install network adapter drivers. Check if this solves the connection issue. If Windows does not automatically install drivers, try installing backup drivers that were saved before uninstalling.
Check if your network adapter is compatible with the latest Windows updates
If you immediately lose network connection after upgrading or updating Windows 10, the current driver for your network adapter may be designed for a previous version of Windows. To check, please try temporarily uninstalling the latest Windows updates:

Select the Start button, then select Settings>Update&Security>Windows Update>View Update History>Uninstall Updates.
Select the latest update and then select “Uninstall”.
If uninstalling the latest updates will restore your network connection, please check if there are any updated drivers available:

In the search box on the taskbar, type “Device Manager” and then select “Device Manager” from the results list.
Expand “Network Adapters” and locate the network adapter for your device.
Select the network adapter, select “Update Driver”>”Automatically search for updated driver software”, and then follow the instructions.
After installing the updated driver, select the “Start” button>Power>Restart (if needed), and then check if the connection issue has been fixed.
If Windows cannot find a new network adapter driver, please visit the computer manufacturer’s website and download the latest network adapter driver from it. You need to know the computer manufacturer and model name or model number.
Perform one of the following actions:

If you are unable to download and install newer network adapter drivers, please hide the updates that caused the loss of network connection.
If you can successfully install the updated driver for your network adapter, please reinstall the latest update. To perform this operation, select the Start button, then select Settings>Update&Security>Windows Update>Check for Updates.

Using network reset
The final step to try is to use network reset. Consider using this step again when the above steps are not helpful for networking.
This helps to solve connection issues that may be encountered after upgrading from earlier versions of Windows to Windows 10. It can also help solve the problem of being able to connect to the internet but unable to connect to shared network drives. Network reset removes any installed network adapters and their settings. After restarting the computer, all network adapters have been reinstalled and the network adapter settings have been set to default values.
Note: To use network reset, the computer must be running Windows 10 version 1607 or higher. To see which version of Windows 10 the device is currently running, select the Start button and then select Settings>System>. About

Select the “Start” button, then select “Settings”>”Network and Internet”>”Status”>”Network Reset”.
On the “Network Reset” screen, select “Reset Now”>”Yes” to confirm.
Wait for the computer to restart and check if the issue has been fixed.
Attention:

After using network reset, it may be necessary to reinstall and set up other network software that may need to be used, such as VPN client software or Hyper-V virtual switch (if you are using this virtual switch or other network virtualization software).
Network reset will set all known network connections to the public network configuration file. In the public network configuration file, your computer will not be discovered by other computers and devices using the network, which helps improve the security of your computer. However, if the computer is part of a homegroup or used for file or printer sharing, it needs to be set to use a dedicated network configuration file to put the computer in a rediscoverable state. To perform this operation, select the Start button, then select Settings>Network&Internet>Wi Fi. On the WLAN screen, select “Manage Known Networks”>Network Connection you want to change>Properties. Under “Network Profile”, select “Dedicated”.

Troubleshooting steps
Check Wi Fi settings
WLAN adapter manufacturers may have different advanced settings that you can make changes based on network environment or connection preferences.
Please check the “wireless mode” setting of the network adapter and ensure that it matches the network function you are trying to connect to. If it does not match, you will not be able to connect and the network may not appear in the list of available networks. “Wireless mode” is usually set to “automatic” or similar options by default to connect to each supported network.
Find wireless mode settings

In the Device Manager, select Network Adapters, and then double-click the network adapter name.
Select the “Advanced” tab and search for the “Wireless Mode” settings. Please make sure to set it to the mode where the network is currently in use.
Wi Fi configuration file settings
Windows uses WLAN profiles to save the settings required to connect to WLAN networks. These settings include network security type, key, network name (SSID), and other content. If you are unable to connect to the previously connected WLAN network, the reason may be that the network settings have changed or the configuration file is damaged.
To fix this issue, please delete (or “forget”) the network connection and reconnect to it. When you forget a network connection, it will delete the corresponding WLAN network configuration file from your computer.
Forget about the internet

Select the Wi Fi network icon on the right side of the taskbar, and then select “Network&Internet Settings”.
Select “WLAN” and then select “Manage Known Networks”.
Select the network you want to forget, and then choose “Forget”.
Afterwards, select the “Wi Fi” icon on the taskbar and try reconnecting to the desired network to renew the network connection.
Check your home layout
Your Wi Fi network may be affected by the frequency band, channel congestion, and/or signal strength of the network.
Check for other symptoms of the “No Internet Connection” icon

Based on the symptoms you encounter, you may also try other troubleshooting steps.
