here is the information given by some commend:

actually, I've tried:

sudo ifconfig wlan0 up

but it does remove the DISABLE in "sudo lshw -C network" session, but my laptop still can't find any wireless access point.

Also, once I click in the "Enable Wireless" in the "Connection menu", the DISABLE comes back automatically!

Besides, I'm using Ubuntu 11.10(latest version).

Please read the last remark from Ultraman at the following location:

https://bbs.archlinux.org/viewtopic.php?pid=924554

Ultraman solved it by blacklisting the acer_wmi module, which your computer has loaded into memory.

Please copy-paste the following command into the Terminal and then press <ENTER>:

gksudo gedit /etc/modprobe.d/blacklist.conf

Using the gedit editor, please ADD the following configuration line into the file:

blacklist acer_wmi

Using the gedit editor, SAVE the change to the

/etc/modprobe.d/blacklist.conf file.

Then REBOOT and retest wireless. This blacklist operation should make the change permanent, even after rebooting.

This should force the Linux kernel to stop loading the acer_wmi module, which is probably causing the kernel to soft block your wireless card via the INVALID "acer-wireless: Wireless LAN" interface.

acer-wireless is for ACER computers, not for Sony or Lenovo machines....
