2: acer-wireless: Wireless LAN Soft blocked: yes -> wlan0 Interface doesn't support scanning : Network is down -> DISABLED Wireless Network controller [0280]: Intel Corporation Centrino Wireless-N + WiMAX 6150 [8086:0885] (rev 67) not working on Sony VAIO VPCEG16FM in Ubuntu 11.04

I have installed Ubuntu 11.0.4 on Windows 7.
My laptop model is Sony VAIO VPCEG16FM.
It has inbuilt wireless card : Intel Centrino Wireless-N + WiMAX 6150
My wireless router is Netgear RangeMax WPN824 v3.

I',m not able to connect to Internet wirelessly.
Looks like Ubuntu is not identifying the wireless card.

Here is the complete output of following command:
sudo apt-get update; sudo apt-get install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rtl|rt2|rt3|rt5|rt6|rt7|usb|witch|wl';sudo dmidecode|egrep 'Manufact|Product'; iwconfig; cat /etc/modprobe.d/* | egrep 'acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|wmi|witch|wl'; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|egrep 'icd|etwork'; sudo lsmod
