I installed Ubuntu 14.04 on my new Yoga Pro 2 and the wireless is not working. It started with Windows 8 on it.
The Network Manager says Wi-Fi is disabled by hardware switch.
I tried putting a blacklist file in ect/modprobe.d as has been suggested in many places. I called the file "blacklist-ideapad_laptop.conf" and wrote in the file blacklist ideapad_laptop
I checked to make sure that the wireless is enabled in the BIOS. It is.
I ran rfkill list all and it displayed:
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
I ran iwlist wlan0 scan and it displayed:
wlan0 Failed to read scan data : Network is down
I ran sudo rmmod ideapad_laptop and it displayed:
rmmod: ERROR: Module ideapad_laptop is not currently loaded.
I ran ifconfig wlp1s0 up and it displayed:
wlp1s0: ERROR while getting interface flags: No such device.
I ran "lspci" and it displayed:
01:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b)
I ran sudo lshw -c network and it displayed:

This No wireless with Intel Centrino Advanced-N 7260 seems to be dealing with a similar issue. It suggests that I need to update my firmware. So I downloaded iwlwifi-7260-ucode-23.214.9.0 from Intel's website. I put the file "iwlwifi-7260-9.ucode" in /lib/firmware and ran "sudo lshw -c network" again. It displayed exactly as before.
After moving iwlwifi-7260-9.ucode to /lib/firmware I ran "sudo modprobe -r iwlwifi" and "sudo modprobe iwlwifi"
Is there something else I need to do install the new firmware?
