    Security or firewall settings might be blocking the connection (Ethernet connection)


    Hi. I have looked every where for a solution to this problem and I haven't been able to find an answer that has worked.


    I don't have this issue when I use my laptop via WiFi, but my desktop computer doesn't have WiFi and the problem is with the Ethernet connection only.


    I am running windows 10 version 1903 - and my problem all started when this new version was installed.


    Things that I have tried: Reset network, reinstall network driver, uninstalled Bitdefender security software, uninstalled VPN, reset modem, called my ISP and they informed me that there is nothing wrong with my connection and it has to be related to Windows 10 operating system.

    :)

    Firewall blocking Ethernet connection?


    Hi, if you're using Wifi, you might try turning Wi-fi sense off.

    Hi Melissa,


    There are instances when a firewall automatically blocks a connection to the network particularly if it’s a network which is quite far from your usual location. To troubleshoot the issue, we suggest checking this support article:
    Fix network connection issues in Windows 10. The said article has steps which directs you on properly disabling
    firewall. Aside from that, it has other troubleshooting options that could help us resolve the issue.



    Don’t hesitate to give us updates on your query.

    Firewall blocking Ethernet connection?


    So I just unpackaged my computer after moving back to the states (been in storage since Oct 1st). Connect everything and it doesn't recognize the Ethernet connection to the Internet. Call my isp to troubleshoot. They have me turn off my firewall in Windows. Right away my computer sees the connection and I connect to the Internet, turn firewall back on and remain connected. After updating my virus definitions I restart. When it comes back up, again no connection. I try the firewall off trick again this time nothing. Any ideas?
