I have two laptops with exactly the same problem since the recent (KB3194496). Both laptops now show both my 2 printers as being offline. The printers are on and the Wi-Fi lights are on. I tried to reload the both printer drivers but the laptop cannot see the printer. I run Malwarebytes and Norton. Norton does not show that it is blocking the printers. I have no idea of where to go from here.
Second problem is that the network connection disconnects on a regular basis. I usually can go into "settings", "network and internet" and manually reconnect to my modem. Quite often though the laptops stops seeing all the available networks and it requires a reboot to reconnect to the network.
These problems didn't exist on either laptop before the (KB3194496) update.
