    Intel AC 7265 WIFI on Thinkpad Helix 2nd Gen intermittently fails to work waking from sleep


      When this happens I have to turn WIFI on and off to regain connectivity.  Have no issue with other devices such as Surface Pro 3 (using Marvell WIFI), Galaxy Note series phones (Broadcom WIFI), etc. via the same 5GHz 802.11ac to TP-Link Archer C7 v2 firmware 149929 dated 9/29/2014.


      Have tried without success:


      - Newest Lenovo and Intel drivers

      - New laptop BIOS update 1.42 dated 1/15/2015

      - Applied all Windows updates including optional KB3000850

      - Removing hidden duplicate virtual adapters in Device Manager


      The only thing that seems to make it work consistently is setting Transmit Power from default Highest to Medium.  Successfully tested twelve sleep/wake cycles whereas normally it would intermittently fail after a couple.


      Can Intel please work with Lenovo to investigate, formulate a corrective action and update the driver/firmware so the burden isn't on the customer?
