I installed Ubuntu 14.04 LTS on an old Acer Aspire 3680 last night. Previous to the install everything worked fine. I was able to connect to Wifi. Since the install I have not been able to.

All I have done so far is this:

  • run software updates
  • opened terminal and ran lspci, which tells me that I have a Broadcom BCM4311 802.11b/g WLAN (rev 01)

Then I ran sudo lshw -C network. This is the output:

  *-network

       resources: irq:17 memory:44500000-44503fff

I than ran rfkill list all. output:

0: acer-wireless: wireless LAN
soft blocked: no
hard blocked: no

At this point I'm thinking I'm just missing a driver, easy fix. But just to cover my bases I ran lsmod | grep acer. output:

acer_wmi               31735  0 
sparse_keymap          13708  1 acer_wmi
wmi                    18673  1 acer_wmi
video                  18903  2 i915,acer_wmi

After checking the support site I came to find 2 possible drivers. I first tried installing linux-firmware-nonfree driver and rebooting. I was still unable to connect. when running the rfkill list all command it now showed soft blocked: yes.

At this point I reinstalled the OS preformed all of the aforementioned steps but this time installed the firmware-b43-installer. Now again after running the rfkill list all command I am once again soft blocked.

I am stuck. Can anybody help me?

You needn't blacklist acer-wmi.

Please get a temporary internet connection and open a terminal and do:

sudo apt-get update
sudo apt-get purge bcmwl-kernel-source
sudo apt-get install firmware-b43-installer

Reboot and your wireless should be working.

I believe the following command will fix it but if not then post the output from the script that I asked for.

echo "blacklist acer-wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf

Reboot
