Problems connecting to captive portal networks that require sign-in
Your device may have issues connecting to the internet if the network you’re on requires you to sign in and accept an agreement to use the internet. This agreement is known as a captive portal sign-in page.
  • Locate the network sign-in page: Browse http:// websites like https://www.google.com/ that the network might redirect to its landing page. 
    • Tip: Enter URLs that begin with http://.
  • Turn off extensions: If you can't find the network sign-in page, turn off any extensions that you’ve installed on Chrome. Learn how to uninstall extensions
  • If you’re able to complete the sign-in but still can’t get online:
    • Disconnect and reconnect to the network.
    • Use your phone or another device to check if you can connect to the network. If you can’t sign in from another device, there could be an issue with the network.
    • Ask the owner of the network if the network offers internet access.
