Hi, I have trouble to connect by wifi card Broadcom chipset 4318. I know that I need to activate this card by kernel module acer-wmi or acerhk or acer_acpi. But I am not able to do it. I tried the acer-wmi. It doesn´t say any trouble but it is not activated. Please help if you solved this trouble. Second question- Is there any other choice to connect wifi without NetworkManager? Thanks.
I’m having the same problem on an Aspire 5020 running openSUSE 11.2 64 bit. This was fine under 11.1.
I’ve been looking through the directory structure
/sys/devices/platform/acer-wmi for a “wireless file” to control the wireless. However there doesn’t seem to be a wireless entry.
A bit more research resolved my issues as follows: -
The wireless is now permanently enabled
Linux Kernel Documentation :: laptops : acer-wmi.txt
I simply had to complete the installation of the B43 driver by running /usr/sbin/install_bcm43xx_firmware as root. Complete instructions found at
b43 - Linux Wireless
Wireless is now working fine under NetworkManager or ifup. This is much better than 11.1 which caused me lots of problems

Good for you in solving your own problem. For your future problems, and for
others that might read this, the lack of firmware was clearly indicated in the
output of the dmesg command. In fact, you should always check dmesg first for
any problem.
