Ubuntu – Ethernet port and WiFi adapter not detected, Ubuntu 16.04

16.04ethernetnetworkingusbwireless

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.
