Need install firmware for wireless on Live USB's

I like to try out Live CD/USB's for fun. But in many cases, the live distro cannot detect any wireless signals, presumably because the proper firmware isn't supported for license reasons.

Basically, I want to find the proper driver and know how to install it to make the wireless network work each time I try a Live USB.

But I'm on a wireless network currently (Ubuntu 10.04 LTS), so surely the needed firmware is already in /lib/firmware and I only need to copy it to the corresponding folder on the Live USB?

If I'm correct, what else do I need to do on on the Live USB?

I did a little search and found this link, ran the command
lspci -vnn | grep -a4 -i net
and got

	Capabilities: <access denied>
	Kernel driver in use: r8169
	Kernel modules: r8169

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8172] (rev 10)
	Subsystem: Realtek Semiconductor Co., Ltd. Device [10ec:e020]
	Flags: bus master, fast devsel, latency 0, IRQ 19
	I/O ports at b000 [size=256]
	Memory at d0300000 (32-bit, non-prefetchable) [size=16K]

That's not always the case. A Live USB functions as a totally seperate media, as in another hard drive. That is something the hal daemon usually takes care of. But anyhow, you will need to edit your /etc/rc.d inet1 (I believe is it) file using a text editor and set ip up manually perhaps. Before doing all that, type in a terminal:


and if no wlan0 comes up, then it needs configuring. If it does come up, then network manager just needs to be activated.
