Turn off Wi-Fi Power Saving? Is there a way to turn off wi-fi power saving mode on Android, i.e. have the wi-fi radio stay on at all times?  I'd rather have a stable, low-latency wi-fi connection and slightly less battery life than a flaky wi-fi connection and longer battery life.  In other words I'd like to enable constant active mode for my wi-fi.

EDIT:  To clarify, I'm talking about the millisecond time scale power saving mode that's part of the wi-fi standard.  This is where the radio wakes up on every beacon, not the minute time scale power saving where wi-fi is disabled completely.
Settings -> Wireless and network -> Wi-Fi settings -> (Menu) Advanced -> Wi-Fi sleep policy -> Never.
