I was trying to install Ubuntu 14 beta 2 on my new laptop--a Lenovo Yoga Pro 2--and I couldn't use the wireless. So, I used rfkill list all, and got the result:

0: ideapad_wlan: Wireless LAN
    Soft blocked: yes
    Hard Blocked: yes
1: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard Blocked: yes
2: hci0: Buetooth
    Soft blocked: yes
    Hard Blocked: no

However when I booted from the USB stick I had just installed from running rfkill list all output:

0: ideapad_wlan: Wireless LAN
    Soft blocked: yes
    Hard Blocked: yes
1: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard Blocked: yes
2: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
3: hci0: Buetooth
    Soft blocked: yes
    Hard Blocked: no

Using sudo modprobe -r ideapad_laptop && sudo rfkill unblock all got the wireless working. And I can't figure out why phy0 isn't in the install there, how to load it in, or otherwise get the wireless working.

If you issue those commands, is the wireless working as expected? Are you asking how to make the change permanent? –  chili555 Apr 9 at 12:44
    
If I issue the commands when booting from the USB stick the wireless will work, if I do a clean install and do them on the newly installed system it will not work. It will not work because as mentioned above on the system rfkill shows 3 drivers, on the USB stick it shows 4, once the command is issued on the installed drive there simply isn't any wifi driver at all. –  Patrick Jeeves Apr 9 at 13:45
    
I think you have two problems here; the buggy ideapad_laptop and the wireless driver. What is your wireless card? lspci -nn | grep 0280 Thanks. –  chili555 Apr 9 at 15:01
    
@chili555 lspci -nn | grep 0280 produces: 01:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b2] (rev 6b) –  Patrick Jeeves Apr 9 at 16:04
    
Please check the log for errors: dmesg | grep iwl –  chili555 Apr 9 at 16:10

I suggest you install the latest firmware for your device. Please get a temporary wired ethernet connection, open a terminal and do:

cd /lib/firmware
sudo wget https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/plain/iwlwifi-7260-7.ucode
sudo modprobe -r iwlmvm
sudo modprobe iwlwifi

Detach the ethernet and the wireless should now be working.
