Wireless Question

[MICHAEL J MARCINIAK]

Greetings. Trying to get my wireless card working, and this is as far as this newbie can get.

Compaq Presario v5005us

Broadcom BCM4318 [AirForce One 54g] [14e4:4318] (rev 02)
Wireless "on" button does not work on physical machine (did light up
on it's own before installing Ubantu in Windoze and wireless worked).
nm-tool reports "Driver:b43", "State:unavailable"

I did connect to a USB wireless adapter, and it updated several
"drivers" and such on it's own. But, nm-tool reports a driver, it seems
I just can't "power" it on on the laptop itself.

running "sudo lshw -C network" reveals the driver, version, but firmware=N/A.
Is this a Compaq firmware missing issue (hence the physical "on" button
doesn't work)? Can I update this somehow even the firmware most likely
is Windoze only, or am I just hosed? It even lists the MAC address.

Ubuntu r11.04 (natty)

Thanks in advance for any help
