How can i detect if i can begin setting up a connection through WiFi .

I noticed after powering ON the unit , it takes some time until WiFi is
ready to use (it needs to discover an AP)
During the time the AP is discovered, the WiFi led blinks ORANGE, when an AP
is discovered ,it blinks GREEN

How can i know if the AP is detected, and i can try to build up a connection
..

You could utilize the NetPerceptor control in your CF applications so that
they inherently know when the network is available or not. You can find out
more about this control at http://www.hoodcanalsystems.com. Good luck to
you.

Powering off a device that has an active connection will yield an invalid
connection when the unit is powered off ,and then resumed again. I would
want to detect this , and detection power notification is not enough
I need to know when the PDA has discovered the AP (or vice versa )

Its no use to setup u new connection BEFORE this point.
 
here are my little experiences:
reconnecting to an AP takes between 3 and 15 seconds (depends on the AP or
whatever ) after resuming when we are using DHCP. A possible solution is
using GetAdptersInfo from the OpennetCF and checking the IP-adr..
Then we switched to static IPs for the devices and recognized that
reconnecting was done in less than a second.
Maybe this a a solution for you too.
