Fix Normal Wi-Fi Connectivity Issue in Microsoft Windows

Recently I got work to fix Lan and Wi-Fi issue in an Office. All PCs and Laptops were running on Windows 7, and Windows 10, and they were facing common connectivity issues over Wi-Fi in Windows 10. Windows 10 sometimes do misbehave over poor Wi-Fi connection or because of certain reasons like driver or hardware issue. These problems are not very much hard to solve, and with a few troubleshooting and tricks, you can resolve problems with your Wi-Fi connectivity on your own.

How to Fix Wi-Fi Connectivity Issue in Windows 10

First of all, let's talk about the latest version of Microsoft operating system "Windows 10". Windows 10 have a separate help article for connectivity issue on Microsoft's website (You can find the link at the bottom of this article). But still, there are a few things you can do better and solve your issue just by reading this blog post.
Most common problems in Windows 10 Wi-Fi are as follow:-
  1. Wi-Fi Network adapter's Driver Issue.
  2. Device not connecting to Wi-Fi
  3. Wi-Fi Signal Strong but no connection
  4. Connected successfully but not able to access the Internet.
Most common issue is after an upgrade or Windows update, Windows 10 is not able to connect Wi-Fi. You can try following fixup to solve above problem.

Clear All Pending Updates

Sometimes pending Windows update may create issues so you will need to restart to apply pending updates. Incase updates are stuck then you can try fixing it by starting and stopping Windows update and it's service from Windows 10 settings.

Restart Windows

Sometimes you may have noticed when you plug a new device in your Windows 10 machine, and it starts searching for a driver for that device locally then after in Windows update (if you are connected to the Internet). This process may stick a few time, and this can happen with your Wireless network adapter if its driver is not installed while updating or installing Windows 10. You can remove pending Windows update by restarting.
  • Stop all programs.
  • Restart your Computer.
Once you restarted the device, see if there are any pending installation in the notification tray and Windows update setting. You can also see installed drivers from Windows Update History under same configuration area.

Resetting Windows Update (Be Careful)

This is the second option to try in case of driver update get stuck for the network adapter, and you start facing Wi-Fi connectivity issue. You can reset Windows update completely and while doing this things can be messed up so creating a restore point is always a good idea before doing things like these.
  • Open Start and search for Services (it will appear as a desktop app)
  • Now find and stop "Windows Update" from service list.
  • Once service is stopped rename "SoftwareDistribution" folder to "SoftwareDistribution.old" (You can find the folder in Windows folder in C Drive).
  • Now Start the "Windows Update" service again.
Once everything is done do a restart to properly apply the changes. This will surely clear all stuck driver downloads and you can try again to install driver for your network adapter or manually find and download it.

Device Not Connecting to Wi-Fi

You have all drivers installed and you can see Wi-Fi SSIDs in notificiation area but still not able to connect to any of your Wi-Fi network. If you have similar issue you can try to fix it by resetting your Wireless adapter.
You can reset Wireless adapter from "Control Panel\Network and Internet\Network Connections" and disable and enable your Wi-Fi router from there. If this doesn't help you can try reinstalling your Wireless adapter driver. You can uninstall current driver and use 3dp chip or driver detector to find right driver for your machine's hardware.

Reset Things Manually

You can reset IP stack, Release and renew IP address and Flush the DNS cache manually by using following commands in Command Prompt in admin mode.
  • 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.
