Excuse me for any newbie mistakes I'm making, this is my first time running any Linux distro. I'm running Ubuntu 16.04 off a live USB drive on a Dell Vostro 2510. If I plug an Ethernet cable in, it doesn't show up under network. The cable and connection work fine on other computers, so I'm thinking it's the OS not detecting the port on the computer. The same thing happens with WiFi, the OS doesn't detect the laptop's WiFi adapter.

I've tried disabling and reenabling networking from the taskbar. Here's a screenshot with my network settings: Screenshot

Here's what I get from ifconfig:

ubuntu@ubuntu:~$ ifconfig
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:4852 errors:0 dropped:0 overruns:0 frame:0
          TX packets:4852 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1 
          RX bytes:358752 (358.7 KB)  TX bytes:358752 (358.7 KB)

I'm left with no way to access the Internet on that machine. How can I fix this?

Can you see on taskbar the wifi icon? If yes, click on it & ensure 'Enable Networking' & Enable Wi-Fi is checked. Try this first. Hope it'll helps.

Start Adding your Ethernet first & set all to automatic settings to see how it works.

Click Add button to adding new network

Click Add button to adding new network

Select Ethernet & click Create

Select Ethernet & click Create

Checked the box as in picture

Checked the box as in picture

Key in device address(open terminal, type ifconfig & see HWaddr) set to Automatic & checked Default

Key in device address(open terminal, type ifconfig & see HWaddr) set to Automatic & checked Default

Leave the rest & click Save. See how it works!

  • Thanks for the answer! Networking is enabled already. I turned it off and back on, no change. – Zenon Nov 01 '16 at 01:53
  • No change means working? – Wafie Ali Nov 01 '16 at 01:54
  • No change meaning it's still not working; nothing has changed. – Zenon Nov 01 '16 at 01:59
  • can you edit your questions & paste the screenshot of the event? perhaps we can what's the actual cause of it. Thanks. – Wafie Ali Nov 01 '16 at 02:02
  • What screenshots should I take? – Zenon Nov 01 '16 at 02:04

    the screenshot of your wifi & ethernet settings & if possible. Hope others will help you on this as long as they get noticed on this questions. – Wafie Ali Nov 01 '16 at 02:07

    see my edited answers. – Wafie Ali Nov 01 '16 at 03:19
  • I didn't notice any change, and Firefox still gives me a no connection. Network menu doesn't show a connection, in the settings under last used it says never. The device on the other end of the Ethernet cable doesn't register a connection. – Zenon Nov 01 '16 at 03:26
  • Should there be something in the Device field when I set up the connection? There's a button that looks like it should be a dropdown, but it's grayed out and can't be clicked. – Zenon Nov 01 '16 at 03:35
  • I wasn't sure about this. Maybe you can ignore all the proxy settings first. I just re-update again my answers. Wish you luck. – Wafie Ali Nov 01 '16 at 03:41
  • Ok, I added the results from ifconfig to my question. I don't see any HWaddr. – Zenon Nov 01 '16 at 04:28

    Ok thanks. I thought it will show the HWaddr which is maybe similar to MAC address. just ignore the HWaddr & try to proceed with my answers. Thanks. – Wafie Ali Nov 01 '16 at 04:32
  • Still no network connection. – Zenon Nov 01 '16 at 04:42
  • Why don't you try to install ubuntu on your laptop hard drive or use virtual machines(vm), perhaps? suggestion for vm is virtualbox. – Wafie Ali Nov 01 '16 at 04:52
  • I'll install Ubuntu on my laptop tomorrow, then see if the issue is only with the USB. Originally I wanted Ubuntu on a USB so I could boot it from any computer, but if it can't work with the hardware, there's not much point. – Zenon Nov 01 '16 at 05:16
  • yeah! I got your point. but if you are using vm, it would be better since it will bridged the connections from your main machine, thus it'll be better alternative rather than usb. – Wafie Ali Nov 01 '16 at 05:53
