Yoga2 13 Wifi hardware disabled

Question

Hi there,
i bought a Lenovo Yoga2 13, it comes wirh a Intel Wireless N. It came with an OEM Windows 8.1.
At first the Wireless worked pretty good with no problems but then it would not turn on anymore.
It came after i tried to copy the partition.
Solutions i already tried since:
- enable wireless in bios
- A whole lot of drivers
- reinstall windows 8.1
- installt windows 7 (a solution was described that in windows 7 it could be activatet with the hot key, sadly the hotkey software i found on lenovo could not be installed on the yoga2)
But none worked, in windows 8.1 i can switch the "flightmode" but it switches only the bluetooth adapter. The Wireless adapter stays grey and cannot be switched.
In the device Manager it says that the networkcontroler works fine. (it is activatet)
in the network adapters it is also activatet but has a red corss.
When i use the intel software it tells me "wifi on". if i switch it to off an back to on, the message says that the Hardware Switch is diabled... wich i do not have.
The only solution i found and did not try was with linux, since i do not have linux:

But my Problem seems to be the same, an hard block in the wifi controler.
Can u help me with a windows fix?
Thanks michael

Answer 1

I'm having the same problem. Also on the Yoga2 13.
When I run diagnostics from Intel PROSet/Wireless tools (link from the Network and Sharing Center - available after I installed latest Intel drivers), and it says that the "Hardware radio is OFF". The WLAN is enabled in BIOS. Where is this hardware switch?!
At first, the wireless card seemed to be working. It downloaded and applied several WIndows Updates. After a few reboots, I went to configure other apps and I went into BIOS to enable Legacy boot mode (to boot from USB stick to run a backup and repartition to run other OS). At some point the wireless radio got turned off (sometime during or after the windows updaters and before/after the backup, long before I actually repartitioned), and there doesn't seem to be a physical hardware switch or Fn key combination switch to turn it back on. Windows sees the Intel Wireless-N 7260 in Device Manager, but it says that WiFi is off when trying to connect to a network (it shows as off greyed out).
I did a parallel install of WIndows 8.1 with Update 1, it made no difference. I've tried different drivers (the original that shipped with the tablet, the updated one from Lenovo's site, and Intel's updated drivers) with no effect. I tried uninstalling KB 2903939, 2887595, and 2883200 (which had no effect) and then downloading on a USB key and and reinstalling them in the correct order, still no effect.
