The following doesn't work unfortunately, it takes longer to "kill" wifi but sleep still does. Some people have returned their tablet. Did that solve the issue ? WIFI disapears when the computer goes to sleep. Close the lid then reopen it and you end up having to disconnect and remove the battery. Here is a solution: 1. go in the device manager 2. find the intel wifi and right click to propertie 3. in the power management tab uncheck "allow computer to turn off this device to save power"
