No Internet for Linux guest on Windows Host

[Pingpongofkingkong]

I am using Bridged adaptor, but no ineternet connection for guest. please see screenshots below:

I wouldn't expect to have any sort of connection if the cable is not connected...

[Pingpongofkingkong]

I have both wireless card, and cable card. I tried both, none of them are working.

I have used the same VM on another computer using wireless at home, which works. The above is at work place.

[socratis]

Do you see the "Cable Connected" in the VM settings that is not-checked? That's the problem. The "Cable Connected" needs to be checked!

[Pingpongofkingkong]

thanks. I checked the box now, but I still cannot get internet connection.

Also, no ip address is assigned, please see below:

Please see the screenshot below

Can you try the Bridged-over-wired? The Bridged-over-WiFi may have issues...

[Pingpongofkingkong]

I tried four of the network cards below. Only Ethernet connection is assigned ip address, and can ping host, host can ping guest, but still has no internet connection.

[socratis]

OK, stick with the wired connection then. Post the output of the command:

• ifconfig /a

Try the following commands from a Terminal on your guest. I've included sample output that you should be focusing on:

$ ifconfig
enp0s3    Link encap:Ethernet  HWaddr 08:00:27:40:51:1a  
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0

$ route -n
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         10.0.2.2        0.0.0.0         UG    100    0        0 enp0s3

$ ping <DefaultGateway>    <-- tests your connectivity
$ ping 8.8.8.8             <-- tests outgoing connectivity
$ ping google.com          <-- tests name resolution

Report any misconfiguration, or any errors from the "ping" commands.

If you can ping your "gateway", if you can ping "8.8.8.8", if you can ping "google.com", VirtualBox is working as it should. You should look elsewhere for your networking connectivity. Look in your host for firewalls, proxies, antivirus filters, web-cleaning applications, redirectors, etc.

@socratis

Thanks. I will do that once I have my laptop tomorrow morning.
