I may have found a solution after doing some tinkering suggested in another thread. There has been discussion recently about which programs can be eliminated from Startup folder. Refer to the link below.
I never use Odyssey Client, and I took steps to at least eliminate its autostart. Ever since I have removed the
odClientCeAutoLaunchSmart.exe program from my \windows\startup folder I have noticed that my PDA does not randomly perform a WiFi autosearch after soft reboot. I have done about 6 soft resets now without any recurrence.
I'm thinking that the Odyssey startup may have partially enabled the WiFi driver, at least enough to show the searching icon on the titlebar.
