I just discovered that the WLAN connection on my WM5 Pocket PC (HP hx2410) gets disconnected as soon as I put it in the cradle and ActiveSync connects it to my development machine.
Now I read something about not being able to sync over Wifi anymore, so it might be related to that. But it is quite annoying for debugging from VS2005. In our application we have code which checks and controls the WLAN connection, but as the connection is disabled it doesn't work as it should under the normal circumstances.
Is there any way to leave the WLAN connection enabled during an ActiveSync session And is this something that is WM5 specific or maybe PDA specific

I believe that an Activesync USB connection will always shut down all other connections, and that there is no way to keep them up.
And as you say, since Activesync 4.0, it is true that you can not have Activesync over Wi-Fi any more.
Microsoft apparently have done this for security reasons...
So you can not debug with Activesync anymore, however you can debug without it!

It involves a lot more configuration than the old Activesync way, but it is a workable solution
