Yoga 2 Pro wifi not working after driver update

Question

Hi all, I just updated my brand new Lenovo Yoga 2 (13") from Windows 8.1 to Windows 10. But after doing so, I cannot establish any WiFI/W-LAN-connection! If I go to the settings for network adapters in the system settings, I even caanot find the wireless LAN adapter as if it was not installed at all! Can anyone help me? Is there any source for new drivers or something else to fix this?Thanks a lot and best regards from GermanyJohannes

Hello all. Fisrt of all, this are my specs: Yoga 2 pro 13". WiFi card: Intel(R)Dual Band Wireless-AC 7260. I bought it from Best Buy on November 27, 2014. If you aquired your Yoga before this date, you may have the single band WiFi card. As many of you have experienced, I also had a bunch of issues with my WiFi connectivity and this is how I was able to solve it. At least it has been a couple of days that I haven't had any issues. The first symptom was the usual connection drops every X amount of time. For me it was about every 2 hours. I first unchecked the "Allow the computer to turn off this device to save power" option in the Power Management tab of device manager and disabled U-APSD support in the Advanced tab of device manager. This action did not solve the problem. I then downloaded and updated the driver from the Intel web site (http://www.intel.com/p/en_US/support/detect) and this seemed to solve the drops; however, a new problem arised: Everytime my Yoga would wake up from sleeping mode, all my wifi networks were gone and the adapter showed as disabled in Device Manager. I would have to anable it to have my networks back. It was a solution but a pain the butt to have to do this everytime. After hours of reading post after post in several forums, I read a repy from Lenovo asking to try leaving the "Allow the computer to turn off this device to save power" CHECKED if you were using the latest version of the driver. I went back to device manager and checked it back and that seems to have solved the problem. So far I haven't had any drops and everytime my laptop comes back from sleeping mode the WFi connection is still there! Here is a recap of how everything ended up: -The driver version I installed is 17.1.0.19-The driver date is 7/21/2014-In device manager|Advanced, U-APSD support is Disbled.-In device manager|Power Management, "Allow the computer to turn off this device to save power" is checked. Hope this helps somebody else.
