Can One Increase the Mobile AP Hotspot Timeout? I have a Samsung Captivate (Galaxy S) and I have an AT&amp;T plan that includes tethering.  I can turn on the Mobile AP hotspot and then other devices can connect to it.

However, after several minutes, the Mobile AP turns itself off.  If I manually turn it back on again, it works fine again, but this gets pretty annoying.

Is there any way to make it stay on, or to lengthen the time it will stay on?
Go to your WiFi settings and hit the menu button and click the Advanced menu item.  Check the WiFi sleep policy, and if it isn't set to Never, try setting it to Never to see if this resolves the issue.
