Wake-on-LAN issues with Intel 18260 wireless card installed

Dell laptops with the Intel 18260 wireless card (Dell part number J7Y3C) installed may experience an issue with waking after being re-docked while in a sleep state. When the laptop is reattached to the dock while in a sleep state (the laptop powered on but with the LCD closed), the network card appears to search for a wireless network to join but will not let the laptop wake. A hard reboot is required to get the laptop functioning again. This issue has been reported on the Latitude E7270 but may be seen on additional laptops using the Intel 18260 wireless card.

A new driver is now available at Dell's Support Website which should resolve this issue. If you are experiencing this issue, it is recommended you download and install the latest version (A20 or later) of the Intel 18260 WiFi driver.

You can install the latest driver by following the steps below:

  1. Go to the Dell Support Website / Drivers & Downloads.
  2. Make sure your correct system model and operating system are showing at the Drivers & Downloads site.
  3. Select Network from the Category drop-down menu.
  4. The latest Intel 18260/17265/8260/7265/3165 WiFi Driver will show in the menu. Click the View Details link which will take you to further information on the file, as well as Installation instructions for downloading and installing the update.
