  Hello everybody,
  here's my system description: notebook Acer Aspire 5024 (Turion64 ML-34 processor), onboard Broadcom 4318 wireless card as lspci stats:
  
  0000:06:05.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
          Subsystem: AMBIT Microsystem Corp. Aspire 3022WLMi
          Flags: bus master, fast devsel, latency 64, IRQ 177
          Memory at c0204000 (32-bit, non-prefetchable) [size=8K]
  
  I am using Kubuntu Dapper 6.06 with kernel 2.6.15-26-amd645-k8, and I
  have 2G of ram. I have followed the wiki page
  (https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx/Dapper) with
  the instructions to use Dapper bcm43xx driver, that is:
  
  sudo apt-get install bcm43xx-fwcutter
  zless /usr/share/doc/bcm43xx-fwcutter/README.gz
  
  then I have picked the acer winxp 64bit provided firmware bcmwl564.sys available at ftp://ftp.support.acer-euro.com/notebook/aspire_3020_5020/driver
  /winxp64bit/80211g.zip
  
  then I have extracted the firmware:
  sudo bcm43xx-fwcutter -w /lib/firmware
  
  and then I have removed and reinsterted the module.
  
  
  Then I bring the interface up with
  ifconfig eth1 up
  
  and now iwconfig shows this:
   
  IEEE 802.11b/g  ESSID:off/any  Nickname:"Broadcom 4318"
            Mode:Managed  Frequency=2.437 GHz  Access Point: Invalid
            Bit Rate=11 Mb/s   Tx-Power=19 dBm
            RTS thr:off   Fragment thr:off
            Link Quality:0  Signal level:0  Noise level:0
            Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
            Tx excessive retries:0  Invalid misc:0   Missed beacon:0
  
  
        
  it seems that I can modify transmission rate:
  
  sudo iwconfig eth1 rate 36M
  
  eth1      IEEE 802.11b/g  ESSID:off/any  Nickname:"Broadcom 4318"
            Mode:Managed  Frequency=2.437 GHz  Access Point: Invalid
            Bit Rate=36 Mb/s   Tx-Power=19 dBm
            RTS thr:off   Fragment thr:off
            Link Quality:0  Signal level:0  Noise level:0
            Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
            Tx excessive retries:0  Invalid misc:0   Missed beacon:0
  
  
  but when I try to set the essid or to scan for networks I get a kernel panic; one of the last lines of the oops says "bcm43xx_dma_handle_xmitstatus..."
  
- I have also tried to use wl_apsta.o, downloaded from, but the result is
- the same.
+ I have also tried to use wl_apsta.o instead of the acer firmware, but
+ the result is the same.
