Windows 10 laptop doesn't connect to internet via wifi

I have an HP Pavilion laptop running windows 10. Suddenly it stopped connecting to the Internet through WiFi. Meaning, I can connect to the WiFi but computer can't reach the web. I've formatted and re-installed a fresh copy of Windows 10, but I am still having the issue!

But the laptop's WiFi adapter (Ralink) works fine when LAN gaming. Means laptop WiFi adapter is working right?

What could be a possible solution?

I tried different WiFi networks at my home / university and public WiFi non of these working with my laptop.

On my WiFi status It shows

IPV4 connectivity: internet IPV6 connectivity: no network access

Yes, it means the WiFi adapter is working and what you have is probably a DNS issue. You should try rebooting the router (as this is unrelated to the OS) before anything else. – None – 2017-09-18T18:52:20.330

@MichaelBay I tried few wifi networks (home / university / public wifi) but non of these working. So the problem is with the laptop – Milan – 2017-09-19T15:36:54.207

This looks like the adapter can't resolve Internet addresses. I would recommend you to open a command line window (Win+R -> cmd) and then test this:

ipconfig to see what IP your gateway have (e.g. 192.168.0.1) and to check, if your WLAN adapter got a valid IP address
ping 192.168.0.1 (your gateway) to see, if there is a response.
If the ping was successful you could ping to the google DNS with ping 8.8.8.8
If that was successful, try to ping google.com, if you get an error, then most probably the DNS servers are wrong.
To see what DNS are set, you could do a ipconfig /all and scroll to the DNS section of your WLAN adapter.
To set DNS you could follow this steps: https://www.lifewire.com/how-to-change-dns-servers-in-windows-2626242. You could use 8.8.8.8 and 8.8.4.4 (google DNS) or set it to automatically, if something wrong is set.

I can ping google.com and any other site. But when I tried to open a site in web browsers it can’t reach the site. Says request timed out – Milan – 2017-09-24T05:52:55.487

Is there any other things I can check ? – Milan – 2017-09-24T05:55:11.977

What browser are you using? Could you test with Internet Explorer, and Firefox and a third one like Edge or Chrome? Is it the same with every browser? Check also the proxy settings in "contrlo panel" - "internet options": 1st: http://image.chromefans.org/i100/id127/chrome-proxy-server-1.png then delete untick everything at "proxy" https://i.stack.imgur.com/D0bxl.png

1Have you tried with another OS on the same machine? (like a linux live image) – arielnmz – 2017-09-24T07:01:14.163

@chloesoe I don’t have any proxy. I even tried re installing fresh copy of Windows. - yes I tried different browsers. – Milan – 2017-09-24T12:56:14.247

You reinstalled Windows completely? Strange. I would have checked the windows firewall if the outgoing port 80 or 443 is blocked. Perhaps port 8080 works, test here: http://portquiz.net:8080/. Have you checked on your router? Perhaps the MAC address of your wifi is blocked, but then it's strange you're able to ping into the Internet.

Or try to deactivate IPv6: https://cloud.addictivetips.com/wp-content/uploads/2009/10/IPV6Disabled_thumb.jpg

Initially check device manager , network adapter whether a correct wifi driver is installed in your laptop. If its fine check your router page to see the dhcp settings in order to get the internet working

1If it works in the LAN then it's not a drivers issue. – None – 2017-09-18T20:57:22.160
