Wireless problem

[Harry Hersh]

I just installed Kubuntu on my Dell Latitude D400. The hardwire (tcp/ip) connection into my router works fine but I cannot get the wireless capability to work, even though it did when I was running XT on this hardware. The wireless modem in the laptop is a Broadcom BCM4306, which I understand from browsing around causes problems for many, but being a unix/linux user but not a guru, I can't figure this out. When I try to run
	sudo apt-get install ndiswrapper-utils
the response is that ndiswraper-utils doesn't exist. Same for
	sudo apt-get install bcm43xx-fwcutter -w /lib/firmware ~Desktop/wl_apsta.o.

Can someone clarify what the problem is, and how I might be able to resolve it.

Thanks for your help!
