I've just bought a new laptop and installed Ubuntu 12.04 in it. My problem is that I can make a wired connection but not a wireless one. The wireless network is working okay with other computers but not with the new one. The new laptop can't detect it. Can anyone help me?

On a terminal, typing lspci the output is
00:00.0 Host bridge: Intel Corporation Ivy Bridge DRAM Controller (rev 09)
00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09)

Inspecting the drivers installed the one for the Network controller: Realtek Semiconductor Co., Ltd. Device 8723 is not there. How do I install it?

Thank you

I believe this has been asked and answered already on ask ubuntu. Here is a link to the thread. Wireless card Realtek RTL8723AE-BT is not recognized. Hope that gives you the insight you need!
