Hi, Glad you finally got that driver to install.  Microsoft did a lot of things with Windows 10 trying to lower power consumption on laptops.   In some ways that has caused some issues with wireless connectivity, making cards more susceptible to interference.   Hopefully that driver will clear up a lot of the conflicts and problems that you're seeing. Let us know how it goes. Todd
WiFi intermittent problem.  I have a 2 month old Dell Inspiron 15 5559 with Intel dual band Wireless AC 3160 adapter.  I connect via WiFi, start Pandora with Chrome, and everything works fine for a couple of hours.  I monitor the WiFi status and notice that when the speed indicator temporarily drops to single digits, then resumes at 50 Mbps or higher a second or two later, my browsers (Chrome, Firefox, IE, Edge) no longer work even though the icons indicate "connected, secured" and LAN activity continues.  Pandora and all other browser activity ceases until I disconnect and reconnect.  The router I first had this problem with is a TP-Link wireless-N that works perfectly with other PCs, but I bought & installed a D-Link D604 wireless AC router to see if that might fix the problem.  It has the exact same problem on both the 2.4 and 5 GHz bands.  Device Manager shows an Intel driver version 18.11.0.8 dated 6/22/2015 which appears normal and no ! or ? anywhere in the listing of devices.  So the obvious conclusion is that when the signal strength temporarily drops below 10 Mbps for a second or two, then comes back up, Windows 10 thinks it's got a good WiFi connection when it doesn't.  Disconnecting and reconnecting always fixes the problem, but it's an obvious bug, and it's a pain.
