I have tried everything I can read to try and solve this. I’ve upgraded via dvd to Windows 20H2 in attempting to solve no internet on either Ethernet or WiFi connection!

When I run ipconfig I get no adapters.

    I removed Total AV Anti Virus software, rebooted then reran MiniToolBox with the resulting report attached:

    Hello @1963Fuelie ,

    Kudos for your perseverance - most people would have probably given up by now and bought an Apple Mac :-)

    I too am now "groping in the dark". What follows is my next suggestion.

    Create a file containing the following 6 lines (name it prov.lst, for example):

    Microsoft-Windows-TCPIP
    Microsoft-Windows-NDIS
    Microsoft-Windows-Network-Setup
    {205ce500-a543-56a2-7b6a-67ba089f67dc} 0xFFFFFFFF 255
    {a111f1c3-5923-47c0-9a68-d0bafb577901} 0xFFFFFFFF 255
    {4f50731a-89cf-4782-b3e0-dce8c90476ba} 0xFFFFFFFF 255

    Now issue the following four commands:

    logman start nonet -ets -pf prov.lst -nb 128 -o nonet1.etl
    netsh trace start scenario=lan capture=yes tracefile=nonet2.etl
    logman stop nonet -ets
    netsh trace stop

    The "netsh trace stop" command might take a minute or two to complete - just be patient.

    This should create 3 files: nonet1.etl, nonet2.etl and nonet2.cab.

    nonet2.cab contains nonet2.etl and other diagnostic data that Microsoft finds useful when analysing network problems.

    If you could then make nonet1.etl and nonet2.cab "available" (via OneDrive, Google Drive, dropbox, etc.) and post the link here then I will take a look at them. The files will probably be quite large.

    Hello @1963Fuelie ,

    I just wanted to mention some small anomalies in the data. In the .CAB file, there is a file called "powershellinfo.log" that claims that the WiFi interface is "up" and still mentions the TAP adapter:

    Name InterfaceDescription ifIndex Status MacAddress LinkSpeed

    Local Area Connection* 9 Microsoft Wi-Fi Direct Virtual Adapter 5 Disconnected D8-FC-93-D7-49-F8 0 bps
    6to4 Adapter 2 Not Present 0 bps

    Another file in the .CAB file (envinfo.txt) also reports a reasonably healthy looking Wi-Fi interface:

    There is 1 interface on the system:  
    
        Name                   : Wi-Fi  
        Description            : Intel(R) Dual Band Wireless-AC 7260  
        GUID                   : 8a731490-a9e4-4f8a-aad8-0ffd7a7a471f  
        Physical address       : d8:fc:93:d7:49:f7  
        State                  : connected  
        BSSID                  : 24:f5:a2:ab:af:eb  
        Network type           : Infrastructure  
        Radio type             : 802.11ac  
        Authentication         : WPA2-Personal  
        Cipher                 : CCMP  
        Connection mode        : Auto Connect  
        Channel                : 153  
        Receive rate (Mbps)    : 866.7  
        Transmit rate (Mbps)   : 866.7  
        Signal                 : 85%  
    

    However, other data (that is usually reliable) does not report the Wi-Fi interface as being up. Still plenty of things to investigate...

    Gary
