Dell Latitude E6420 Ethernet working

I test this on Dell Latitude E6420 with Ubuntu9.04 (Desktop)

After Installation found Ethernet not working, even ifconfig shows only lo (loop back device).

So for that run following command.

#lspci -nn

Ethernet controller [0200]: Intel Corporation Device [8086:1502]

After google, found this page.

Then i download driver from Intel site.
