Update:

Please follow this question to install the driver first. The answer is dependent on the kernel version. To know your kernel version you can execute uname -a

Broadcom 4365 wireless driver with 3.4 / 3.5 kernel

eth0 is not wireless adapter. It is Ethernet adapter.

Try sudo iwlist wlan0 scanning | egrep 'Cell |Encryption|Quality|Last beacon|ESSID'

Better, first enable wireless adapter using hardware switch.

then click on top panel network manager button to see the available networks.

  • you don't have intel wireless card. you have broadcom. That makes everything invalid, please post result of `lspci` so that we can help. Edit your question to include the result don't post as comment. – Web-E Jan 17 '13 at 17:27
