Ubuntu Desktop 11.10 AMD64 on Lenovo IdeaPad S205 (E-450)
Wireless is disabled.
In a thread on Ubuntu forum I found the following.
rfkill unblock wifi
rfkill unblock all
modprobe -r acer-wmi
It makes wireless work, but the network speed is awful, below 60kb/s and my old eee netbook that's playing streamed internet-radio through same router drops connections when I connect the S205.
I tried installing Wicd (and removed network manager) with "rfkill unblock all" in rc.local. It kinda works but network speed is unstable, falls in speed after a couple of minutes, and ends up stopping completely.
I tried ndisgrabber blacklisting these drivers in: /etc/modprobe.d/blacklist.conf
Ndisgrabber sees the adapter, but wireless does not show up in network manager. (reinstalled of course).
