I have the same problem. Connect automaticalli box is ticked yet I have to enter the password of the router everytime. Can someone shed some light on this? It's a desktop PC with a 3rd party wireless usb adapter plugged into the motherboard usb slot.
run msconfig (start > run (or just type into the "Search programs and files" field above the windows orb) > msconfig)
this brings up the System Configuration dialog box
click the Startup tab
scroll to find your wifi adapter's startup program
uncheck the box next to this startup item
open search, type "services.msc" open services.
Scroll down to "wlan auto config" right click, stop the service.
"C:\ProgramData\Microsoft\Wlansvc\ delete everything in this folder leaving only a folder called "profiles" delete everything in the "profiles" folder except for a folder called "interfaces" delete everything in the "interfaces" folder)
Restart "wlan auto config" connect to your wireless network, enter
your passkey, (ensure the connect automatically box is checked)
Restart your computer job done, your computer will now connect to your wireless network automatically on boot.
