WLan on Acer Aspire 5020 (BCM 4318) and Ubuntu 8.04

Hello again!

After the update from Ubuntu Gutsy to Hardy, Update of the kernel and deleting of the old kernel, wlan wasn't working. From posts in some forums I saw, that acer-acpi is now enclosed in the kernel AND got backported to the actual Hardy-kernel.
In addition to the normal kernel I installed the "backports"-package.
In order to get wlan working I had to open a konsole and

sudo modprobe acer_acpi wireless=1

and

sudo echo 1 > /sys/devices/platform/acer_acpi/wireless

.

cat /proc/acpi/acer/wireless

should give you a 1.
On my system after reboot, wlan is starting automatically now.

Hope, this helps!

cya!
