Hi all, new member to the forum, and new to the Android world. I have a new Samsung Captivate, and I can't keep the wifi off. No matter how many times I go to settings (or use the pull-down curtain), and switch off the wifi, within a minute or so, the wifi comes on again. It also turns itself off again periodically when this happens. I don't have any after market power manager installed. I suspect this may be down to an app, but have no idea where to start looking for the solution.
