wireless card net-install

I am trying to do a network install on my laptop. I downloaded the boot-only cd of 7.1-BETA2.

My wireless network card is identified in boot. But when I try to configure network in sysinstall for ftp install it cant find any networks.

I know its hard with wireless but is it possible somehow to do an ifconfig or something during boot/installation? Or do I have to take the whole cd and install from cd instead and then do the ifconfig settings?
I think it'll be easier just to get the regular install disk (only the first one), do a mini install and go from there.
That's how I usually do it, even wired.
yeah I guess so.
is this needed:

in 7.1 or is it default loaded in GENERIC these days?
