http://ubuntuforums.org – I have a fresh installation on my Lenovo laptop Y470, which has a Intel Centrino Wireless-N 1000 network controller. Now the problem is that I can't access my wifi router under ubuntu, but it's ok under win7. First I'm very sure that both my hardware switch and soft switch are on. Below is output from ' rfkill list all' Code: nico@jacob-pc:~$ rfkill list all 0: ideapad_wlan: Wireless LAN     Soft blocked: no     Hard blocked: no 1: ideapad_bluetooth: Bluetooth     Soft blocked: no     Hard blocked: no 2: hci0: Bluetooth     Soft blocked: (Hardware)
