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.
