Lenovo yoga 8 weak wifi

I have just bought the lenovo B6000-f and the connection to the WiFi is very poor. Even if I'm in the same room as the router. How can infix this?

Dear Ashah
Welcome in lenovo community
If you are sure that currenlty all networks are working fine with the other machines, so please use the below link to download and install the latest update of the wifi card ,
Note : you will need to uninstall the existing one first and then install the new driver once you install it .

Lenovo Yoga 2 Pro: WiFi doesnt work after driver upgrade

After experiencing Wireless issues I tried to upgrade my Lenovo Yoga 2 Pro 13" with Windows 8.1 64Bit to the latest drivers from the lenovo support site.
Ever since I cannot connect to the WLAN anymore. What puzzles me is that the driver status in the device manager shows a different driver version than what I have installed (uninstalling the driver and reinstalling it doesn't change anything here).
What puzzles me is the Lenovo Website shows driver version 16.6.0.8 (released 25.Jan.2014, see link below), whereas my system display version is 16.6.2.1 (dated 31.10.2013). Hence I thought I have another version from somewhere else on my and removed all driver versions I could find.
Checking driver details I get the follow file versions:
   C:\windows\system32\drivers\NETwbw02.sys    version 16.6.2.1 Intel, dated 2011
   C:\windows\system32\drivers\Netwfw02.dat       no version or publisher
   C:\windows\system32\drivers\vwifibus.sys          version 6.3.9600.16384 Microsoft
Still, whenever I deinstall the driver, install the files from lenovo and click "Detect new device" my system pulls the drivers as listed above and is incapable of connecting to any WiFi.
Windows 8.1. shows no connections available and doesn't connect anymore.
How can I get my WLAN back?

hi Florian,
If Windows Update is configured to automatically fetch updates from Microsoft then the machine most likely have installed the Intel driver update for Intel(R) Wireless N-7260 as discussed in this article (which explains the different driver versions).
Things that you can try:
1. If the machine comes with the Intel(R) Wireless N-7260, navigate to:
- Device Manager
- Network Adapters
- Intel(R) Wireless N-7260 (right click > update driver software)
- Browse my computer for driver software
- Let me pick from a list of device drivers on my computer (you will then see a list of drivers, check if you have the version 16.6.0.8 from Lenovo and choose it and observe.
2. Restart the machine and boot into the BIOS (by pressing F2 on the Lenovo screen). Once you're in, navigate to the Configuration Tab and ensure Wireless is set to Enabled (if applicable).
- Link to picture
3. Perform a System Restore and choose a date before the issue began. (this will restore the unit to an earlier point in time where wireless connection is working fine)
4. Perform a Refresh / Reset or press the OneKey Recovery button (this will restore the unit to factory settings - ensure that you backup important files first).

Lenovo Yoga 10 HD+ WIFI connection stability issue

Same problem here but on Lenovo Yoga 10 HD+ 3G:
After a few minutes the connection is gone though the tablet shows its still there at full level. Disabling / Enabling WIFI on the tablet makes it reconnect. On the same router e.g. Lenovo Yoga 8 Wifi Edition, Samsung Galaxy S3 and S3 mini all work fine and do keep the connection. Tested with latest firmware released OTA yesterday.
Also tried the Yoga 10 HD+ on two other WLAN routers where it worked fine.
Any ideas except for buying a new router?
Moderator Note; post moved to start new thread on specific system

I'm having the very same problem. I bought a Lenovo Yoga 10 tablet about a week ago and updated it to 4.4.2 (B8000_A442_001_021_140703_WW_WIFI) yesterday and ever since then, my wifi kicks out when I'm browsing, reading emails, checking twitter etc just all of a sudden and I have to disable and re-enable my Wifi for it to work again (aprox. 5-20 minutes until I have to reconnect again). I've not changed anything in my router settings (Netgear CG3100) since the upgrade and every other computer, tablet and phones that we have in our house runs all fine, it's just the Yoga tablet where I have this issue with. I really hope an update/fix could be pushed as soon as possible since it's unbearable to use it right now and I might just have to return it to the shop in exchange for another tablet, which I don't really want (love the battery life).
Eitherway, I'd be thankful for any help/fix or responds from Lenovo.

Lenovo Yoga 2 13, Kali Linux 1.0.7, Ubuntu 14.04, Windows 8.1 install, config, and wifi fix.

Lenovo Yoga 2 13, Kali Linux 1.0.7, Ubuntu 14.04, Windows 8.1 install, config, and wifi fix.
I wanted to share an experience with everyone I hope will help others avoid what I have gone through the past 3 days. I bought a Yoga 11s that I loved but had some issues with the wireless, Lenovo being awesome replaced it with a Yoga 2 13. I love this laptop but ran into some issues with Linux install/wireless, which I wanted to show how to resolve in one place. Hopefully this will help someone else get through this quicker
I am going to try and write this for someone with little Linux experience, if I miss the mark please let me know and I will clarify the best I can.
For work I need Windows 8.1 and Kali Linux, while for home I prefer Ubuntu.
My Yoga 2 13:
I5 1.6 ghz
8 GB ram
256 GB SSD
ORANGE!
My requirements:
I need Windows
I need Kali Linux (livecd, even with persistent mode was not an option as it would not save the wireless fix or system updates) – I would also like this on a USB drive and not the internal SSD
I would like Ubuntu
Needed to do this:
1. 2 USB thumb drives (at least 8gb in size each) I used 2 Leef Supra 32GB drives. They are my favorite right now and are only about $27 at amazon.
2. Phone that can USB Tether or a USB Ethernet card (External USB wireless will show as "Hardware Locked"). Again you can pick one up for sub $10 if you need the USB Ethernet route. I used my Galaxy S5, you will need to download 200-300 mb of items through this so make sure you have the data if you go that route.
3. You may be able to get a USB wifi card to work if you do the following after boot. This only worked once for me.
                a.Type ‘sudo rmmod iwlmvm’
b.Type ‘sudo rmmod iwlwifi’
4. ISOs of Ubuntu and Kali Linux (I used Ubuntu 14.04 and Kali Linux 1.0.7)
5. Software to unzip the ISOs. I recommend 7-ZIP and will be referencing this in this guide.
6. I will include the EFI boot files and the WiFi fix files if I can attach. Otherwise I will provide a link to them.
   Link: https://www.dropbox.com/s/puxnnoft3gn2b6l/WiFiFix.zip
Recommended (these are just in case you corrupt something making your system not see any OS
1. I would call Lenovo beforehand and get a set of recover disks (this will take 2-3 days)
2. In the meantime a USB Windows 8.1 or 8 ISO (the repair feature may save you)
*Note: At many points in this guide I detail steps and commands. Please double check that you understand the step before proceeding. There are multiple points where a mistyped command or clicking the wrong option will cause your entire system to fail and you will need to reformat the entire drive and start over. This also will make One Touch recovery not work. Proceed with caution.*
I did not need to disable ‘secure boot’ to do this, but keep in mind that you may need to.
Steps:
First let’s go through the installs, and then we will go through grub config and wireless fix
1. In Windows scroll to computer and right click, select manage.
2. Go to “Disk Management”
3. Select the main HDD (notice Lenovo puts a stupid number of partitions on here)
a. I deleted the D: drive on here, if you do this make sure to copy the drives over to your main C: drive. You will want to run each of the installers and repair the drivers after.
4. I used the space from the D: drive and pulled a little more creating a 50 GB partition for Ubuntu and my swap file
a. You can also add more space by right clicking your C drive and selecting shrink
b. Do not format the partitioned data as this will make identifying it later much easier.
5. Open a command line
                a. Swipe from the right of the screen and select search
                b. Type ‘cmd’
                c. right click and select ‘run as admin’
6. For Ubuntu: Type ‘diskpart’ into the command line
                a. type ‘list disk’
i. You should see 2-3 disks depending on if you have one or both usb drives in the laptop at the time. I would suggest only doing 1 at a time so you don’t lose track.
                b. type ‘select disk $’ (Replace the $ with the number of the drive)
c. ***** Before proceeding make sure you have the correct drive selected or you can ruin your Windows install and Lenovo one touch recovery will not fix it since we have changed the partitions *****
d. type ‘clean’
e. type ‘create partition primary’
f. type ‘active’
g. type ‘format fs=fat32 quick’
h. type ‘assign’
i. type ‘exit’
6. For Kali Linux: Type ‘diskpart’ into the command line
                a. type ‘list disk’
i. You should see 2-3 disks depending on if you have one or both usb drives in the laptop at the time. I would suggest only doing 1 at a time so you don’t lose track.
                b. type ‘select disk $’ (Replace the $ with the number of the drive)
c. ***** Before proceeding make sure you have the correct drive selected or you can ruin your Windows install and Lenovo one touch recovery will not fix it since we have changed the partitions *****
d. type ‘clean’
e. type ‘create partition primary size= 3272
f. type ‘active’
g. type ‘format fs=fat32 quick’
h. type ‘assign’
i. type ‘exit’
j. By doing this we can maintain a portion of this drive as the install CD and still have linux install/ liveCD if we need to run it on another machine.
7. At this point the drive is ready to have the contents of the ISO copied over.
8. Right click the ISO and select 7-zip then ‘zip to /’ This should unzip the ISO to the location of the ISO into a folder named exactly the same as the ISO.
9. Once this is done for Ubuntu ISO it is done
10. Kali requires a little bit more to be ready
                a. Kali will need some files added for EFI boot. --$--
                               i. Thanks to: https://forums.kali.org/showthread.php?271-How-to-EFI-install-Kali-Linux
                               ii. EFI files are located within the wifi fix folder https://www.dropbox.com/s/puxnnoft3gn2b6l/WiFiFix.zip
11. Now let’s start with Ubuntu
Ubuntu install
1.     Place USB drive into the laptop and press the “Lenovo boot” button next to the power button
2.     Select ‘Boot Menu’
3.     Select ‘EFI USB Device (Name of drive)’ Mine stated Leef Supra
4.     Select ‘install Ubuntu’
5.     Go through the Ubuntu install until you get to select the install drive
6.     Once you get to the install portion it will ask you to select from one of 4 options. Select ‘Manually select partition’
7.     Select the “Free Space” where we opened up some of the drive
8.     You will need to create 2 partitions, I usually create the swap partition at the end of the drive
a.     First I create the swap
                                          i.    Set at the end of the drive
                                         ii.    Set size to 1024 mb
                                        iii.    Set type to ‘swap’
b.     Second create the ext 4 partition
                                          i.    Set to beginning of drive
                                         ii.    Set to remainder of the space
                                        iii.    Set type to ext4
                                        iv.    Set mount point to /
9.     Finish the install and boot into Ubuntu
10.   You will notice that your wireless is ‘disabled by hardware’ This is fine for the time being and we will worry about this after the kali install. If we fix it now for some reason after installing kali we get the error again and would just need to fix it again.
Kali Linux install
1.     Place USB drive into the laptop and press the “Lenovo boot” button next to the power button
2.     Select ‘Boot Menu’
3.     Select ‘EFI USB Device (Name of drive)’ Mine stated Leef Supra
4.     From the grub menu select ‘install kali linux’ both graphical and text work. I much prefer text install
5.     You will get a few errors through the install but that is fine
6.     The first we see is about network hardware and ‘load missing firmware from removable media?’ – Select ‘no’
7.     Then select no ethernet card
8.     It will have you name your machine then it will ask you for the root password
a.     If you want to just use root *not recommended* place the password here
b.     If you wish to use a non-root account then leave these blank and it will ask you for a name, username, and password of the new machine *Very Recommended* - this will also add this user to the sudoers file
9.     It will then ask you to ‘partition disks’
10.   Select manual
11.   Now here is where it can get a little confusing so read twice click once
12.   Select the USB drive from this list
13.   Mine shows up under (sdb) – Leef Supra
a.     It could be sdc, sdd, sde, etc… depending on how many drives you have plugged in.
14.   You should see one primary drive that is 3gb or so that is formatted as FAT32. – DO NOT TOUCH THIS PARTITION!
15.   You should see the remainder of this drive as ‘FREE SPACE’ select that
16.   Create a partition at the end at size 1024mb and swap
17.   Then create another one for the remainder of the drive and set it to ext4 with mountpoint of /
18.   Continue through the install after you should see an error warning you that ‘you may not be able to boot’ that is fine, select continue
19.   Then select from the menu of all the options ‘continue without bootloader’
20.   It should finish up then reboot on its own.

First setup/boot/fix grub
1.     You should be able to boot up into GRUB2 menu now.
2.     You may not see kali linux in this menu (make sure you have your towel and don’t panic!)
3.     Boot into Ubuntu
4.     Once you log in you should see that you still cannot use wireless due to being locked by hardware
5.     This is expected
6.     Let’s fix grub then we will come back to fixing wireless
7.     Plug in your device to connect to the internet (USB Tethering or USB Ethernet)
8.     Once you verify that you now have an internet connection run the following from terminal
a.     ‘sudo add-apt-repository ppa:danielrichter2007/grub-customizer’
b.     ‘sudo apt-get update’
c.     ‘sudo apt-get install grub-customizer’
9.     You can also edit the grub.cfg manually if you know what you are doing… I did not
10.   Open grub customizer
11.   It should auto populate and you should see ‘debian (kali linux)’ somewhere in the list
12.   It should be mounted to /dev/sdb2 or /dev/sdc2 depending on how many devices you have
13.   At this point go ahead and save
14.   Reboot and test that you can get into each OS
15.   This is where my inexperience got me. I spent 2 of my days so I am including this error: If when you boot into Kali you get an error somewhere that says ‘/bin/sh: can’t access tty: job control turned off’ look above it for an error that looks similar to ‘ALERT! /dev/sdc2 does not exist. Dropping to a shell!!’
a.     That error is due to the mount point being incorrect in grub, reboot and from within grub highlight the kali boot. Press ‘e’ then towards the bottom you should see ‘root=/dev/sdc2’ change this to ‘root=/dev/sdb2’ again the number doesn’t matter just make sure it stays the same.
b.     Press F10
c.     If this boots fine then you will need to go back and fix the grub.cfg or load into Ubuntu and open grub customizer again, it should fix this
16.   Now you have 3 working OS on the machine with one being on a USB! Congrats!
17.   You can remove the USB with no worry of screwing up your install, but you will not be able to boot into Kali Linux until you replace it. I would suggest only removing it and replacing it while the machine is powered off, but that’s just me.
Fix Wireless
Now is the time to do what probably ¾ of you came here for. FIX THE DANG WIRELESS. This is a huge problem from Lenovo’s side that I hope they realize how important Linux is and will fix. I won’t hold my breath though.
Log into Ubuntu : This is well documented in the following forum post on page 3 by user Haohe:
http://ubuntuforums.org/showthread.php?t=2215044&page=3
His has you download quite a large file, mine should be much smaller.
https://www.dropbox.com/s/puxnnoft3gn2b6l/WiFiFix.zip
1.     Download the attached package with the fix.
2.     Connect your USB internet device (tether or ethernet)
3.     Place the packages somewhere easy to access, in this example I will place them under ~/Desktop/WiFiFix
4.     Type ‘cd ~/Desktop/WiFiFix/’
5.     Now we need to prep the tools we need.
6.     Type ‘sudo apt-get update’ – we did this before, but you know, just in case
7.     Type ‘sudo apt-get install linux-headers-`uname –r`’   Note around uname-r they are the ` symbol not the ‘ this is located just above the tab on the same key as ~.
8.     Type ‘make’
9.     Type ‘sudo cp /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/ideapad-laptop.ko ~/ideapad-laptop.ko.backup’
10.   Type ‘sudo cp ~/Desktop/WiFiFix/ideapad-laptop.ko /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/’
11.   Type ‘sudo modprobe -r ideapad-laptop’
12.   Type ‘sudo modprobe ideapad-laptop’
13.   Type ‘sudo rfkill unblock all’
14.   Type ‘sudo modprobe -r ideapad-laptop’
15.   Type ‘sudo mv ~/ideapad-laptop.ko.backup /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/ideapad-laptop.ko’
16.   Next we need to blacklist the ideapad module
17.   Type ‘sudo echo 'blacklist ideapad-laptop' > /etc/modprobe.d/blacklist-ideapad.conf’
a.     The first time I tried this it wouldn’t work. So I did the following
b.     ‘sudo touch /etc/modprobe.d/blacklist-ideapad.conf’
c.     ‘sudo vim /etc/modprobe.d/blacklist-ideapad.conf’
d.     Enter     blacklist ideapad-laptop
e.     Exit and save
18.   Reboot your Yoga 2 13
19.   Boot into kali and see if you have wireless, if you do then you are done. If not we will need to repeat this process with one small little change.
Kali Wifi Fix
1.     Copy the sources.list from the package provided
2.     Replace /etc/apt/sources.list with the included
3.     Some of the file path changes but the process remains the same from here.
Congratulations you now have 3 OSes one portable to other machines and working wifi!
Thank you

Lenovo Yoga 13 WIFI Problem - making sense of the problem

Hi Lenovo
For the past 3 days i have been doing some research and observations in order to try to make sense of this wifi issue and maybe someone will come up with a solution.
Lets start
First of all i assume that when this laptop was being developed some form of testing was done before it was released, so the wifi must have worked well within lenovo offices.
Also not everyone is having this issue - some people claim no problems at all, whilst others whathever they try they can't seem to be able to fix it. Some even send their laptop for repair, other even had it replaced, yet the problem still persisted.
So the problem seems to be related to one factor - the router people are using.
Some people have a router that works well with this laptop, and so have no issue.
Other have a router that is "not compatible" with the wifi card and so no matter how many lenovo yoga 13 machines they have it will still not work.
I also noticed in my situation that when i use my android phone or tablet as wifi hotspot i have no issues, yet when i use my home router its a nightmare.
Also i noticed that chaging the way how the laptop connects to the router can make a difference;
1, At first i used a fixed IP with alternate configuration - this was horrible (continous disconnection, routers wifi crashing, takes ages to connect)
2, Then i used fixed ip in the general configuration - ths was better, yet still problems (yet disconnections were less, yet still took long to connect and at times router's wifi crashed)
3, Dynamic Ip - this is the best configuration - connects quickly, does not disconnect, yet internet connection slow and at times routers wifi crashes.
So i think its a question of compatablity with the wifi network you are using.
Also based on this i do not think this is a hardware issue - since hardware problems tend to be all or nothing - whilst in this case if one connects to a "compatable" router the connection is good.
So this is a driver issue and thus if lenovo puts some effort in this - it can be fixed - yet this doesn't seem to be the case unfortunately.
What can help from our side if everyone posts the routers and connection settings (e.g. static ip, dynamic ip etc) they are using and stating whether their wifi is working or not.
Maybe we can close down on the problem and find a fix asap.
Let me start with my configuration.
Samsung galaxy s2 and samsung note 10.1 - wifi tetharing - works fine
Belkin Pre-N router with dynamic ip and wpa2 password - problems

Solved!
Go to Solution.

I had the same problem. I came across someon that found a fix. My Yoga is restoring right now (I tried windows 8.1, it didnt work outwell) so I can't tell you the exact steps but it goes something like this.
1.) right click my computer
2.) click properties
3.) Device Manager
4.) open properties of WiFi device (under network adapter)
5.) Go to Advance
6.) there is an option to use use either 20_40w or 20w under one of the energy/power related options in this list.
(This is part I can't remember off the top of my head) - Turn to 20w instead of the variable rate.
6.) Change the Bandwith option from 20_40w to 20w.
5.) OK out till your at your desktop (might require Reboot, I dont remember)
That is how I kept my WiFi from destroying my Wireless networking in my house. I was rebooting my WiFi network hourly before.

Lenovo yoga 213 wifi card not working in the new laptop

I purchaed lenovo yoga 213 from Best Buy Boston and have brought to India.From the day one,the Bluetooth and Wifi is not working.On taking to their authorised service centr-Hitech technologies they have tried to replace the wifi card but even they are not able to solve the problem.I am trying to contact Lenovo for replacement of Laptop,but there is no response from them.What should I do?

Lenovo service centre has done all these after getting a replacement card
from Lenovo and again they have reported that the wifi replacement card
recieved is defective ,so they have asked for 2 nd time replacement of
wificard as well as the touchpad which they say carries the antenna for
wifi.The bottom line is i am tired of running around to service centre and
have not been able to use the laptop from the time i have bought the
laptop.I thought if there is a manufacturing defect lenovo,being a reputed
brand will replace the laptop.

Lenovo yoga 10 2 1050LC update to android 5.0 lead to wifi disfunction.

Hi,Lenovo yoga 10 2 1050LC update to android 5.0 lead to wifi disfunction. The wifi page do not recognize any signal of wifi networks. I did these tasks to solve the problem, but all failed:1- airplane mode on/off combined with wifi on/off2- delete all saved wifi networks, and refress, the page freezes on:" searching wifi networks ...."3- restart set/wifi modemPlease put the patch or somthing to solve the issue, would be very gartefull.Kisses

My Phone company is Irancell I havent tested MCI the other provider but I dont think that may be the problem since as soon as you insert the sim into the tablet the wifi is gone !PS: I dont think anyone from lenovo is reading this or else you would agree that in a standard support procedure thay would at least let us know about it request a log etc ... I was surprized to see a multinational brand in a leading It tech branch dosent have a meaningful support contact or ticketing system and expects its customers to solve their own problems.as much as I am like many others depended on my tablet for bussiness and study I think I shoud consider changing my brand and would definitly recommend this to " dose who don't".I'm not sure if lenovo is even support its channel parthners in Iran like the ones mentioned in earlier posts.

Lenovo Yoga disables WiFi for all devices

I have a Lenovo Yoga 2 that connects fine via LAN cable, but when i disconnect and try to use WiFi it disables my wireless router for all devices. The wireless router works fine for windows phones, android phones and other laptops. The Yoga disables WiFi every time it connects - is there some setting i can change to fix this? how do i diagnose what is going on? I've checked Ipconfig /all but it looks normal. Any ideas? thanks

Sounces like the network is overloaded, or there's interference.
Try ethernet.

Lenovo Yoga 2 Pro connecting to 5ghz dual band wifi?

I just found something strange. Under Windows, my lenovo yoga 2 pro does not see my 5ghz wifi connection (from my dual band router). But I just booted under Linux Mint, and was able to connect to the 5ghz connection without issues. Any idea why this would be?

Dual Band: 2.4GHz and 5GHz at the same time:
Your MBP can connect to both.
If the Bands each have a different Name, you can choose by hand, if not it connects to the strongest signal.
Click the wireless icon and you see the name of the network you are connected to, If you see the other band name you can choose that.
Click the wireless icon in the menubar while hoding the Alt(option) key: it gives the specififcs of the band you are connected to.

[REQUEST] rtl8723au_bt bluetooth driver for lenovo yoga 13

Hello.
I have a lenovo yoga 13 laptop with 8723 wireless card.
Wifi is working bacause of dkms-8723au-git package. As I know, in 3.15 kernel it will work out of the box and lwfinger will no longer maintain this source code.
Bluetooth is not working and there is no bluetooth driver in aur. It is required to install another package from here https://github.com/lwfinger/rtl8723au_bt.
I cannot build this package, because when I run make command it ends with error make[1]: *** /lib/modules/3.14.4-1-ARCH/build: No such file or directory. Also there was written about no dkms support in code. But I cannot fix it, because I am still noob in Archlinux. And for some reason it is written "Support kernel version 2.6.32~3.13.0" in readme.txt. I have already 3.14.4-1-ARCH kernel.
Could anyone help me to fix that and make aur package for other people to get bluetooth work on lenovo yoga 13?

I think bluez5 is ok, because when I run bluetoothctl it can detect my cluetooth controller now. However, I cannot start working with it

Lenovo Yoga Windows 8.1 Update Solution Thread

Before you attempt anything, I would suggest you read it first . This is probably not a conclusive guide for everyone's situation.
I updated to Windows 8.1 about a couple of hours ago and it's screwed up everything. I noticed users on this forum having a load of problems too so here's my 'roughish' guide on resololving all the issues that affected me (Lenovo Yoga 13 (2191))
Lenovo have release some official upgrade literature (incl rough solutions)
http://download.lenovo.com/lenovo/content/windows8-1/upgrade/ideapad/index_en.html
You are going to need to download new drivers and reinstall a few apps.
Windows 8 Drivers (Back them up - Do not delete them)
This is what I've done. All of your drivers will be stored in c:\Drivers if you haven't got a custom installation. I would move everything in there into a new folder (C:\Drivers\Windows 8) so you have a historical backup because the Windows 8.1 may not upgrade them all.
Windows 8.1 Drivers
Go here;
http://support.lenovo.com/en_GB/
Click Drivers & Software and search Yoga. This link should take you directly there but they never seem to post right on forums so...
http://support.lenovo.com/en_GB/downloads/detail.page?DocID=DS032590
Change the filter to show Windows 8.1 as the OS. Download everything it displays and save it in a new folder (C:\Drivers\Windows 8.1).
Now you have all the new drivers ready to install. Go into your C:\Drivers\Windows 8.1 folder and install each thing in the list on by one. If they request a reboot I would suggest you do that before progressing onto another driver. Do this until everything is installed.
At the time of writing the drivers include;
Bluetooth/Wlan, Camera, Card Reader, Chipset (Important), Management engine, Alscontrol, Dynamic Platform & Thermal Framework & Graphics.
WARNING:
Updating Wifi drivers it may reset your settings (lose network passwords etc) so you may need to get your wifi pass to hand or skip this driver if you have no problems.
Graphics
My graphics went blurry. This was due to the HD graphics driver. This is in this pack. This fixed it for me, but in case it doesn't totally fix your problem, there is a suggestion to change a setting if problems persist of your graphics (Thanks Ezekial)
1. Right-click on Desktop and select "Screen resolution" option.
2. Now click on "Make text and other items larger or smaller" link.
3. It'll open "Display" settings page. You can also directly open "Display" window by selecting "Personalize" option from Desktop context menu and then click on "Display" link given at the bottom of left-sidebar.
4. Now enable "Let me choose one scaling level for all my displays" option and apply the changes.
5. Restart your system and your problem will be fixed.
Trackpad
If you have a problem where you lose your trackpad like I did, you can uninstall in that device manager but I would suggest you are careful in there. You can then click actions, and scan for hardware changes.
Get to Device manager this way;
Right click My Computer/This Computer and click manage. Down the left side look for Device Manager.
When updating the drivers (anything with an exclamation mark) you should right click and update drivers. Search in your new folder. If you installed all the above drivers you may have nothing here.
Airplane Mode Hotkey/Function
To fix the problem with the AirPlane mode not working you will need to go back to the above downloads page and change the filter to Windows 8 and look in Power Management. You will need that. I had to run it with Windows 8 compatibility and Run as administrator.
Lenovo Transition/Auto-Rotate/Keyboard Disabler
Download this;
http://driverdl.lenovo.com.cn/lenovo/DriverFilesUploadFloder/36071/Win8_lenovo_transition_x64.exe
(Thanks to the other th3is & mikey94025)
Uninstall Lenovo Tranisition.
Reboot.
Reinstall the downloaded version. If it fails at the end, reboot. If it's still sketchy uninstall, reboot and install again but with Windows 8 compatibility. Hopefully you won't need to do that though.
Sound
This was broken. Drivers haven't been updated so in device manage update from your "C:\Drivers\(Windows 8)" folder
Bluetooth
I haven't tested my bluetooth yet, but if your's is broken the drivers are in your "C:\Drivers\(Windows 8.1)" folder if you downloaded the drivers linked above..
Others
Citrix Receiver (I wouldn't expect this to affect the majority of you)
My desktop version of this broke. Maybe my custom installation, but a reinstall with the same commands fixed this.
Windows Update
I would suggest you enable this and make sure you are up-to-date. Swipe in from the right and search for update. Find Windows Update.
I would also update other apps & drivers (link on that page to download an update to enable this.
I don't seem to have any other problems. The support page Is not all completely relevant IMO and it has some drastic views on what you should do to upgrade. Just take note that McAffe may have also broken, so be careful on the net as you may be unprotected.
You may want to run through Device manager on anything you are still having problems with. Also depending on the age of your yoga there may still be other things you could update, but unless you have a problem, I wouldn't really worry too much.
Windows 8.1 also no longer pins your apps to the start page by default. Now just swipe up from the bottom to find your apps if you want to pin them or just search for them (swipe in from the right)
Good luck!!! Sorry if I missed anything.

Can you be more specific with the below, as I can't make sense of what you're referring to? I don't know what element size is at all, or where to change it. And, I don't know what you mean by unchecking a checkbox in the device manager as there are no checkboxes. More guidance and specifics would be appreciated.
* Change the element size back to recover from blurry text
* Go to device manager and uncheck that checkbox for the first of the USB devices in HID so that the touchscreen does always react on the first touch (this setting has been lost during the update process)

Yoga 2 13 : wifi hard blocked

Hello,
Sorry for my "English"..I'm French :-)
I bought recently an Lenovo Yoga 2 13 inch.
Since few days, Windows doesn't let me activate my Wifi card.
It is well configured...it's a REALTEK card inside.
I use now an USB ethernet adapter to have access to Internet (and to have the capacity to create a post on this forum ).
I don't remember exactly when this occured.
I think it was after the "tablet mode" but I'm not sure of that because I tried that before and that worked.
I tried a lot of solutions :
- Windows 8.1 option to enable the Wifi => can't be done, it writes that in "grey" color
- disable/enable the wifi card
- connect/disconnect the wifi card
- configurate an static ip address => cmd / ipconfig doesn't show the ip address, so that really means that the Wifi card is not activated
- auto-diagnostic Windows
- Windows device manager=> the card is well configured
- Windows system restore to a previous point where the wifi card worked => it is still disabled
- Lenovo system restore factory settings => it is still disabled
With this last point, I think the problem is at the hard level.
I read other solution using an Live Linux and using the "rfkill" command.
Result :
root@ubuntu:~# rfkill list
0: ideapad_wlan: Wireless LAN
   Soft blocked: no
   Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
   Soft blocked: no
   Hard blocked: yes
2: hci0: Bluetooth
   Soft blocked: no
   Hard blocked: no
root@ubuntu:~# rfkill unblock all
root@ubuntu:~# rfkill list
0: ideapad_wlan: Wireless LAN
   Soft blocked: no
   Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
   Soft blocked: no
   Hard blocked: yes
2: hci0: Bluetooth
   Soft blocked: no
   Hard blocked: no
I tried to unblock specifically the wifi card....same result!
The card is still "Hard blocked".
No change when I start again under Windows 8.1.
Any help is welcome...Thank you so much for your attention and participation. :-)
Solved!
Go to Solution.

mine has intel card and had the same issue. and i accidently fixed mine today.
I first tried with livecd fedora 20 , and tried rfkill method but did not seem to fix. tried to update the kernel but could not because the limitation of livecd.
then i tried to do full installation of fedora 20 to a usb, booted up with the usb , did kernel update, install rfkill, installed kernel-devel (which i planned to use for compiling ideapad-laptop fix ) then rebooted the laptop into new kernel.
When I was about to compile the ideapad-laptop fix that posted around the internet, i ran 'rfkill list all' to check the status, magically all blocks were gone, and my laptop wifi started working again. I don't have any logical explaination for what happened. just posted here hopefully it will help someone here.
i feel the agony everyone has with this issue, and lenovo support and response is extremely disappointing.
To summary what I did.
installed FC20 livecd to usb A
boot from usb A to do full install to usb B
boot from usb B , update kernek, install rfkill and kernel-devel
reboot from usb B with updated kernel
suddenly , 'rfkill list all' shows all blocks are gone.
still no logical explaination how this solved the issue.

New Lenovo yoga 2 13 Wi-Fi not working consistently AND killing my router

I just got my new Lenovo yoga 2 13 and the internet is spotty. Occasionally I can connect to my Wi-Fi for hours at time, but usually what happens is the following:
Let's say the network is working fine. I am connected on my yoga. I open a web browser and maybe get to see one site before my connection status changes to"limited". At this point, all of the other devices in my home (my cell, PS3, wife's HP laptop) lose connection as well.
What is happening? My current solution is to turn Wi-Fi off on yoga so at least other devices can connect, but that makes my new yoga kinda useless.

Where do I find my OEM Lenovo Yoga IdeaPad 13 Windows 8 activation key?

Hello, a couple of days ago, I received my Lenovo Yoga Ideapad 13 in the mail. I turned it on and soon noticed that Lenovo had really screwed the pooch on how they partitioned the device. The SSD was 128GB but only 60GB was given to the C drive. The rest was either on the D drive or in some hidden partition.
I almost immediately proceeded to do a clean install of Windows 8.
I procured an ISO of Windows 8 and ran through the install process. For this post, I'm going ot ignore some of the issues I ran into in this process (wifi not working by default) and cut right to my current problem: I cannot legally activate Windows 8 unless I have a valid activation key. Where is this key found?
The "About Windows 8" post on this very board says that it should be found somewhere on my laptop, but I couldn't find it. I even played with the idea of opening up the ultrabook to see if it was on the inside. I decided to hold off on this until I can get a professional tear-down guide from iFixIt or something.
In the meantime, where do I find my key?

It is either on a sticker somewhere on the laptop Usually on the bottom side of the laptop. Or it is attached to a card in the documents that came with laptop. My Toshiba laptop shipped with its Windows 7 code in both places. There was a sticker attached to the bottom of the laptop and there was another Genuine Windows Card that was mixed in with all the manuals that also contained the number. I would look there as well.
