Acer Aspire 5020 BCM4318

--------------------------------------------------------------------------------

Hi,

Jaunty 9.04 is great, but Acer Aspire 5020 computers still need some help for wireless. But this time is very easy:

1 - Install Jaunty Jackalope
2 - Restart computer
(If you go to System>Administration>Hardware drivers,
Broadcom card may not be listed)
3 - Stop computer (restart is not valid)
4 - Connect by LAN cable (internet connection is needed)
5 - Go to: System>Administration>Hardware drivers
6 - "Broadcom B43 wireless driver" should be listed, activate it
(if is not listed, :s, try stopping and starting computer again, or wait ... I don't know)
7 - Open a terminal (Applications>Accessories>Terminal)
8 - Type: sudo /usr/share/b43-fwcutter/install_bcm43xx_firmware.sh
9 - Stop computer again

Wireless should be working when (and for first time, even the front button works)

YEAH........
