Cannot connect to Wifi network



  • Since yesterday, there is no connection to my home wifi network on PC, Windows 10. Firefox works all fine and I am able to connect other devices. However, Vivaldi and Chrome do not work.

    The following error appears when trying to load a webpage [I do not have a proxy set; have already reset firewall settings to default; also tried resetting my IP address; updated Bitdefender antivirus; none has worked]:

    *There is no Internet connection

    There is something wrong with the proxy server, or the address is incorrect.
    Try:
    Contacting the system admin
    Checking the proxy address
    Running Windows Network Diagnostics
    ERR_PROXY_CONNECTION_FAILED*

    Is your Wifi on the PC connected by USB?



  • @gwen-dragon No, no USB used.

    But strange is that Chrome and Vivaldi can not connect over Wifi.

    Do they need special authentication to use the Wifi?

  • @ayespy Thank you. Unfortunately neither of the 3 solutions worked...



  • @gwen-dragon No special authentication requested. They are both also enabled in the Windows Firewall allowed apps.

    @danonino It's puzzling, to be sure. I use Vivaldi and Chrome on three different WiFi networks, on Windows and Linux, on a regular basis, and there are no problems. If you were to experimentally uninstall bitdefender (not "disable" it), I wonder what would happen.

    There certainly is no obvious reason why there should be a problem.
