I have added external lan card of intel pro/1000gt but thats not showing in Ubuntu
 

I am running Ubuntu 12.04 based distro (Elementary OS Stable) My motherboard is:

**Asus p5kpl-am se**

The Lan Card is: Intel PRO 1000/GT Desktop Adapter

I am trying to add an external lan Card so that I can connect on Lan and Internet both at the same time. After connecting the Lan Card in PCI slot I do not find the card in the system.

**The output of the ifconfig -a command is as below:**

**Then I ran lspci command and the output is as below:**

I have found that the card is fine but the bios was having some thing weird. I reset all to default in Bios and the card is appearing in ifconfig command.
