My Windows 10 WiFi connection has recently become unreliable.  It is lethargic, up/down, and not dependable.  It has been fine until recently, when the latest Windows 10 update was loaded.  It is my only network connectivity option, so I need it.  AND, if/when I lose my network connection, I cannot manually reconnect back to the network.  BUT, if I restart my system, it automatically reconnects.  That is a burden, as it disrupts my workflow.  What will correct my WiFi issue??  Thanks much....
