I have a Acer Aspire 5755G laptop running Ubuntu 12.04. But the wireless is not working. It is normally turned on/off with Fn & F3 but that dose nothing that i can tell. How can I get it to work.

Thanks
Mark

Can you post the output from:

sudo lshw -C network

and

lspci -vnn

( I only need the sections that contain “Ethernet controller” from that command)
and

rfkill list

and

ifconfig

and

iwconfig

and

iwlist scanning

Try this:

sudo apt-get install --reinstall bcmwl-kernel-source

then

sudo modprobe wl

Now see if wireless works … you may need to do the Fn+F3 thing :slight_smile:

If that doesn’t work … send the output from the above commands in my last posting … but be aware, there will be TWO sections that contain “Ethernet controller” from the:
lspci -vnn
command … not just one.

Now working

Thank You
