When I start or restart (from hibernation) my pc the wireless connections are not there. I have to manually start WZCSVC from a command prompt. The settings for the Wireless Zero Configuration service in services.msc is set to Automatic.
Until I do this, I don't see the Wireless Networks tab in the Wireless Network Connection Properties window. Once I start WZCSVC I then see that tab and I have to manually check the Use Windows to configure my wireless network settings box.
Once that is done the wireless works fine, until the PC is turned off or hibernates and I have to do it all over again.
