It has been long time since Windows10 is released and the most amazing part of it is you can upgrade to Windows10 freely from your current Windows 7, 8 and 8.1. Many of us has already upgraded to windows10 but due to some reasons most of the users are again downgraded to their old windows. One of the main problem among them is no WiFi after upgrade, what ever we do the WiFi doesn't work at all. So, here is the solution that might help you:
First don't forget to check your WiFi button or switch is ON, unless it is ON nothing will change and always install the latest software updates. So, check the manufacturer site and see if any new updated driver sometimes it might fix the problem by installing the new version.
Still your problem is not solved? Then try the below solutions:
1. Enable/Disable your network adapter:
After upgrading to Windows10 your network adapter (LAN) or WiFi adapter may be disabled, you must enable it for functioning of WiFi. For enabling go to Control Panel>Network and Internet>Network and Sharing Center on top left side click on Change adapter settings, if your LAN adapter or WiFi adapter is in grey color than it indicates they are disabled. To enable right click on adapter their you can see enable option click on it and this will enable your networking adapter and your WiFi will start functioning.(Sometimes you have to restart your computer after enabling)
If your network adapters are already enabled and still WiFi is not working, then try disabling and enabling the network adapter. Still problem not solved? Then try next solution.

In some computers their may not be separate power management tab then go to Advanced>Power Saver>Change it to OFF.
4. Windows Firewall
Windows Firewall may be blocking all incoming WiFi signals. So, turn off your firewall for once and check if it works. For turning off go to Control Panel>System and Security>Windows Firewall>Turn Windows Firewall on or off(On left side).
Caution! Turning off windows firewall means your computer is exposed and won't block any potential harmful software or incoming connections. So, do this at your own risk.
If WiFi started functioning after turning off Windows Firewall and you doesn't want to turn off windows firewall permanently and turn it on, then change the settings so that even when firewall is on your WiFi works:
Windows Firewall>Advanced Settings>Inbound Rules scroll down to Core Networking and make sure that you enable all the private and public networks, but not the domain except for DIAL PROTOCOL SERVER(HTTP-IN) & iSCSI SERVICE and next scroll down to Network Discovery, select YES to all private and public, NO to domain.
