wireless disabled by hardware key -> eth1 Failed to read scan data : Invalid argument -> Wireless Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01) not working on HP 550 laptop in Ubuntu 10.04.3 LTS

I am very new to linux.
I just installed Ubuntu 10.04 but can seem to get my wireless internet up and running.
I got the following details:

ramon@ramon-home:~$ 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 | grep ound; dmesg | grep irmware ; dmesg | grep ipw; dmesg | grep eth; dmesg | grep ath; dmesg | grep b43; dmesg | grep wl; dmesg | grep witch; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart
