Broadcom wireless BCM4306 keeps dropping connection
 

On FC14 this wireless card keeps dropping the internet connection.
Trying to re-connect fails.
The only way to re-connect is to reboot.
I'm running a dual boot system with XP installed.
In Windows everything works fine.
Is there a way to configure the card in linux?
Can I use the Windows drivers?
Here is the outputs from lspci and iwconfig:
lspci:
00:0c.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03)

Any help would be appreciated, this is driving me nuts!!

What driver do you use, b43? Do you install firmware for b43?

Fedora 14 recognized the wifi card and installed its own drivers and firmware.
b43 drivers.
Windoze uses the BCMWL5.sys drivers which are a lot better, no drop outs in windoze.
Anyway to extract the drivers from that windoze file???
