If you guys try going to Control Panel, Network and Internet, Network Connections, right click wifi, click properties, then click configure, click on the power management tab, and uncheck the box that says, allow the computer to turn off this device to save power.
yes, tried that when problem first appeared. Plus all the other suggestions. Wifi still dropped a dozen times a day
For me that intel driver diagnostic updated to a better version of the driver.... since then i probably only lose wifi once or twice every couple of days which is bearable (if not acceptable).
