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.

Means I can connect to the wifi but computer can't reach the internet.

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:

  1. 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
  2. ping 192.168.0.1 (your gateway) to see, if there is a response.
  3. If the ping was successful you could ping to the google DNS with ping 8.8.8.8
  4. If that was successful, try to ping google.com, if you get an error, then most probably the DNS servers are wrong.
  5. To see what DNS are set, you could do a ipconfig /all and scroll to the DNS section of your WLAN adapter.
  6. 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

  • 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: image.chromefans.org/i100/id127/chrome-proxy-server-1.png then delete untick everything at "proxy" i.sstatic.net/D0bxl.png

    Have you tried with another OS on the same machine? (like a linux live image)

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

    If it works in the LAN then it's not a drivers issue.
