no usable wireless interface

Hi, I have just installed arch on my computer, and when trying to connect to my wireless network, I ran the iwconfig command.  I got this output:

 lo       no wireless extensions
eth0   no wireless extensions 

According to the beginners' guide, this means I have no usable interface.  I was able to connect to the internet through wireless to install arch.  Can anyone help?

Re: no usable wireless interface

If you want some help with this, more information - like your wireless card, would be of some assistance...

Have you installed the firmware for that card?

Re: no usable wireless interface

And what does dmesg say when you do that?
