Hi Larry,
> From your information , and I have googled this bug
report:https://bugs.launchpad.net/ubuntu/+source/linux/+bug/938630,
and I have tried `rmmod acer-wmi`, the nm's "enable wireless" button
now is not unchecked again( great !), but nm still cannot scan for
wireless ssid. sadly :(

Thanks.
