Help, Im a noob!

Basically, Im still new to Linux, so please bear with me. Im running an Atheros wireless card in an Acer Aspire 4720Z notebook. Ive run Ubuntu on my notebook before, but I had someone else set it up for me. Now I dont have any help.I need help setting up my wire less so I can get rid of my ethernet cord. Can someone give me advice or tips, or even just tell me how to do this? Well thanks in advance.

Anyone? I really dont understand how to get the firmware on my noteook and how to install madwifi.

I think I may have installed Madwifi. I really dont know. How do I find out?

have look at the Howto’s

You have to install two RPMs: madwifi and madwifi-kpm-kernel_keyword. Have a read of what you need to do here:
Madwifi or Ndiswrapper Wireless Network Drivers - Suse/openSUSE 10, 11 - LAN & Internet access
Just skirt around the ndiswrapper stuff and focus on madwifi

Well, that guide was nice, but when it says I need to configure my wireless card, I cant. YaST doesnt give me the option. Am I doing something wrong?

Also, YaST says I’m missing firmware for my wireless card.

So where do I get the firmware and how do I install it?

I tried to find that notebook’s technical specifications on the net and couldn’t. We need to know what wireless interface it has.
So what wireless interface does it have?

To help us help you, open a shell (aka terminal, command prompt, etc.)–if you installed KDE, you can start the Konsole program. Type

/sbin/lspci -v

into the window, and hit enter.

Somewhere in the output, you should see something like (taken from mine):

02:02.0 Ethernet controller: Atheros Communications Inc. AR5212/AR5213 Multiprotocol MAC/baseband processor (rev 01)
        Subsystem: Askey Computer Corp. Device 7084
        Flags: bus master, medium devsel, latency 168, IRQ 22
        Memory at e0200000 (32-bit, non-prefetchable) [size=64]
        Capabilities: <access denied>
        Kernel driver in use: ath_pci
        Kernel modules: ath_pci, ath5k

This says, among other things, that I have the AR5212 Atheros chipset. Something like this will help us greatly.[/size]
