I am COMPLETELY new to Ubuntu, like literally, I only know a few commands and stuff for terminal.. I recently installed it into my laptop to learn it more but for some odd reason my wifi wont pick up, nor will it accept wired connections.. Im currently running version 12.04 and I'm in dire need of assistance. I wish I could give you guys more to work with but im stoked, i have no idea how to fix this. I tried changing my interface settings(gksu gedit /etc/network/interfaces) to

auto eth0
iface eth0 inet dhcp

with was a method i found on google but no luck.. Can anyone help me out please????

-EDIT-

when I type dmesg | grep -i eth i get this

What is the manufacturer and model number of the device that you are using to connect to the internet with a wired connection? Is this device a modem or is it a router? –  karel Jun 18 '13 at 7:49

If your wireless device is not supported in linux, you could try Ndiswrapper there is a gui in the software center: ndisgtk. I have never needed it, but you could give it a try.

can i install it offline?? and how do i do so? whats the command? –  Siren Jun 18 '13 at 7:58
    
@Siren I guess you could download the packages here, also make sure to download all the dependencies. But it works more easy if you could find an Ethernet cable to plug in... –  Wouter Jun 18 '13 at 8:06
    
I have one, but it wont pick up, and i notced in ym network settings the wired was set too off. i set it to on, left,then went back to it it was off again –  Siren Jun 18 '13 at 8:10
    
oh sorry I misread, did the wired connection also not working before you made the changes in /etc/network/interfaces? –  Wouter Jun 18 '13 at 8:15

You might want to include info about your laptop.

Using a 12.04 live disc for testing might be your option.

The live session should automatically find any active eth0 and connect to it.

If there is a wireless signal nearby it will also advise that a connection is available.

This you should be able to connect to with your access password for the wlan0.

If neither is occurring then you must have an issue with on board LAN & / or on board wireless device/s.

Good luck

Look up this Old "Ubuntu help" for the Dell Driver on your Vista machine.

https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper#Configuration

And this for the ethernet connection.
