After more searching on compiling issues for the acerhk module that I thought was required for getting my wireless going, I dug up the following discussion:https://bugs.launchpad.net/ubuntu/+sour ... bug/555828
of which the self-explanatory most relevant part was :
I too was frustrated by this, having struggled for months to get my laptop wifi running on Ubuntu before discovering acerhk, only to be facing the same problem again! However, I discovered that Acerhk appears to be no longer maintained. Instead, use acer-wmi. I have tried out the following and it works in Lucid rc and Karmic - probably in earlier versions too as acer-wmi has been round for a while.
If you have acerhk, remove it with:
sudo modprobe -r acerhk
then install acer-wmi:
sudo modprobe acer-wmi
You should now be able to connect to your hub via Network Manager. On my FSC Amilo Li 2735, this works straight 'out of the box' on a fresh install with no ethernet connection, though some laptops possibly require extra drivers.
To tidy up, and make wifi run automatically at start-up:
sudo nano /etc/modules
Delete 'acerhk' if present, and add 'acer-wmi' (without apostrophes) to the bottom of the text. Press Ctrl + O, then press Enter, then Ctrl + X to save and close. I also used Synaptics to remove acerhk and acerhkgui
That was a tough one. thanks for helping!
