Made ndiswrapper work with:
 rfkill unblock wifi
rfkill unblock all
modprobe -r acer-wmi

But network speed is again very low, less than 70-80kb/sec.

Title:
  RT3090 wireless conflict with acer_wmi

Status in “network-manager” package in Ubuntu:
  New

Bug description:
  Ubuntu Desktop 11.10 Oneiric Ocelot  AMD 64 on Lenovo Ideapad s205
  (E-450)

  Wireless is disabled in network manger.

  In a thread on ubuntu forum i found this.

  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 (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
  blacklist acer_wmi
  blacklist rt2800pci
  blacklist rt2800lib
  blacklist rt2x00pci
  blacklist rt2x00lib
  blacklist rt2860sta

  Ndisgrabber sees the adapter, but wireless does not show up in network manager. (reinstalled of course).
