No Wireless Internet Connections Show Up!

Question

Just got Ubuntu on another computer and I've never had this issue. On Windows Vista, (the operating system alongside Ubuntu) The internet works fine. But when I click on the icon in the top right, no Wireless Networks show up. I don't know tons about Ubuntu so be detailed in your replies and tell it to me like I know nothing. The help would much appreciated!

Output of ifconfig

eth0      Link encap:Ethernet  HWaddr 00:25:64:47:a6:62

You are missing your wireless driver. Just do the following: Connect your laptop to internet using the cable, open application called "Software & Updates", go to tab "Additional Drivers" and there select to use proprietary driver for your wireless card.

Your wireless network card may not have native support on Ubuntu. Firstly check if Ubuntu can detect your network card by running the command lspci or lsusb depending on whether your network card is pci/usb based. It should show something like this:

04:00.0 Network controller: Qualcomm Atheros AR93xx Wireless Network Adapter (rev 01)

Now open the link below and check to see if your network card has support.

https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported

Also looking at ndiswrapper may also help as it allows Ubuntu to run Windows wireless driver

Not to be a moron...but how do I know if my network card is pci or usb based??? – user314302 Aug 17 '14 at 20:27
If the network card is internal (inside your computer) then it is a PCI network card whether it be a desktop/laptop but if the network card is a USB dongle connected via a usb port then it is a usb based network card. Alternatively if you are still not sure you can just run both the commands and check the output for a network controller on the list of hardware. – Michael Lindman Aug 19 '14 at 03:57

go to your terminal and type this command

$ gedit /etc/modprobe.d/blacklist.conf*

update:
add "sudo" at the beginning of the command above:

$ sudo gedit /etc/modprobe.d ......

then you want to find where it says:

#causes no end of confusion by creating unexpected network interfaces
blacklist eth[a number here]

and add a hashtag before the line like this:

#causes no end of confusion by creating unexpected network interfaces
#blacklist eth[a number here]

reboot your laptop, and you should be good
