I've just upgraded to Windows 10 from Windows 8.1, but after upgrading I can't connect to the Internet. I select my Wi-Fi network and click "Connect". Even though it says it's connected, I cannot open any page and the troubleshoot helper says that I'm not connected to any network.

How can I fix this?

  • Is your WiFi protected with a password? Did you enter it correctly?

  • @NoneOfYourBusiness Yes, I've entered it correctly. Windows says it's connected.

  • Can you ping the gateway? e.g. ping

  • Good to see this question and answer solve a few issues others had, original thought it was a specific configuration I had when experienced this that was a virtual Wifi-bridge with the problem until I spotted these options were changed! Aug 6, 2015 at 15:21
  • I have a similar issue. Pls see superuser.com/questions/1023244/…

Make sure the IPv4 and IPv6 protocols are enabled:

  • Go to Advanced Network settings
  • Go to Network and Sharing Centre
  • Go to Change Adapter Settings


  • Select Properties for the Wifi Adapter (right-click your connection):

  • Make sure the IPv4 and IPv6 protocols are selected

I also couldn't connect to internet after upgrading and found that these had been disabled. Once enabled you should be able to connect.

    That solved it! Thank you. Not sure why Windows disabled all of those during upgrade, must be some sort of bug.

  • Great glad that worked - I had no idea why it did that it was seemly connected fine but getting no internet, was very strange until I checked this! Jul 30, 2015 at 10:31
  • @RoguePlanetoid all these options are enabled on my HP EliteBook 840 G2 running Win 10 (21H2 OS Build 19044.1415) with Intel Dual Band Wireless-N 7265 WiFi card but still it is not able to connect to the SSID on TP-Link Archer C80 AC1900 router but it connects to the SSIS on Netgear R6220 AC1200.

After sleepless weekend got rid of this problem. It is Bitdefender TS in my case. Uninstalled it and Internet came back in a flash. Also updated all drivers for my Mobo Gigabyte D3H B85M from official site to Windows 10. Re-install latest version of Bitdefender TS. All fine now. Thank God.

  • So you updated all your drivers, and you still argue that it's Bitdefender TS (a.k.a. "total security") that was the culprit? You should have had a look at the answer above before you updated the drivers. It might have saved you at least one good night's sleep. Because when you re-installed drivers, one or several of your network devices may have become enabled (if they were previously disabled).

  • I know I'm a bit late, but I just wanted to say thanks, this solution did work for me (I was also connected but with no internet). My problem was the Comodo firewall; right after I uninstalled and restarted, the internet was working fine.

  • It was ESET for me. Looks like anti-virus/firewall programs can have compatibility issues.

  • For me it was Avast! It is recommended to remove anti-virus of all types as one of the steps to trouble shoot this. I didn't do anything with the drivers; I just read a bunch and picked the least harmful, easiest solution first (after ipconfig, other simple trouble shooting steps).
