If you are using WPA-PSK then the connection is likely always available.
However... there are some vendors who's hardware doesn't connect until a
user is logged in. This is rare.
Additionally, it you are using IAS (RADIUS) to authenticate the WPA
connection, remote access policy will determine whether or not access is
granted. When the PC boots, it will try to authenticate using the domain
machine account, once a seer logs in, the OS reauthenticates in the user's
context. This means that you need to make sure that your computer accounts
are added to the security group that allows for wireless access. If the PC
doesn't meet the remote access policy req. then the machine part of the GPO
will not be applied until the GPO refresh (default 8 hours) , assuming that
the user is still logged in.
To be sure of the behavior, take the time to disable your windows firewall
and boot a machine and ping it. If you get no response, you know that
either the machine was not granted access or that they Wireless NIC hasn't
associated yet. The IAS logs will be pretty clear as to the state of the
connection.
I recommend
http://www.deepsoftware.ru/iasviewer/ to make easy work of
understanding the logs. It's free to try and cheap if you like it.
Hope that helps,
