Its really very troublesome when your wifi adapter stops working in between you are surfing or downloading  something important and you dont know how to solve the Wifi issue. For me my Wifi Adapter Crashes when I switch between 2-3 Wifi Hotspots simultaneously.  It usually makes the “Connected Networks” tab in system tray “Not Responding” or sometimes it takes a lot of time  for connecting and later leads to  “No Internet Access” or in worst case “Cannot connect to the Network”. And even If you try connecting it later you wont be able to connect to the network.
