Fixing Network Problems Ubuntu 10.04 on Dell Inspiron 14R N4010

A few days ago i bought a Dell Inspiron 14R N4010 notebook with pre-installed Windows 7 Home Premium 64-bit Operating System. But as a developer, i need to dual-boot this notebook with Ubuntu 10.04 Lucid Lynx. Although there are some bootloader problems with dual-boot Operating Systems, the Ubuntu installation was successful.

The problem come with the all of network interfaces, both of wired and wireless NIC wasn't able to be detected while installing and after installing the OS. For make it easier let's look what NIC that the Dell Inspiron 14R N4010 had:

1. Wired LAN : Atheros AR8152 PCI-E Fast Ethernet Controller
2. Wireless LAN : DW1501 Wireless-N WLAN Half-Mini Card (Broadcom)
