So the sleep policy is set to never. This is on a fresh factory reset (did it before the reset too). No applications installed at all. It's a tmobile tab that I use without a sim card, just on wifi. It works fine, if I keep it awake wifi will stay on and connected. Any time I leave it for more than a few minutes and wake it up, it is no longer connected and I have to turn wifi off and back on again to get it to connect. Whats up here?

I was playing around with the Wi-Fi sleep policy settings and I am little bit confused how it really works.
The default setting is something like: "turn off wifi when screen is turned off".
So as I understand it it should disable wifi when the screen is turned off.
However when I checked my device list at my router it seemed that my n1 was still connected through wif, even after the screen was turned off. Only after 5-10 minutes wifi was really disconnected (when I turned on the screen again the wifi symbol in the top bar appeared after some seconds). I read somewhere that there is a difference between disabling wifi and disconnecting wifi?
BTW. the wifi sleep policy is supposed to save battery because it is said that 3G in idle mode requires less power than a wifi connection, but I read that with the nexus one the opposite is true. so what's the truth?
It's normal for the wifi to disconnect after several minutes of inactivity once the screen turns off. As for your very last question, I don't know... but I imagine that idle 3G is less power intensive than active wifi, otherwise it wouldn't be the default option...
Hi,
I have flashed my N1 with CM6.1.1 around 2 weeks ago. I'm really satisfied with this ROM.
However, I have noticed my Wi-Fi has gone a little bit weird after flashing CM. Regardless of the Wi-Fi sleep policy setting, my N1 won't turn off the Wi-Fi after it's locked. When I unlock my N1, I can watch the wi-fi icon disappear and then re-appear after a few seconds.
Now I have to manually turn off the Wi-Fi before locking my N1 to conserve the battery. Does anyone know how to get rid of this bug?
Thanks.
i will give you one tip which is its better to leave wifi ON when your phone goes to sleep because it's much better for battery life. if you let wifi turn off during sleep, the phone switches to 3g data which drains far more battery than leaving it on wifi.
now about the disconnect issue, i'm not quite sure what you're seeing. i have a problem with cyanogen 6 where my wifi disconnects for about 3 seconds, and this happens about every 10 minutes or so. its very annoying. but when my phone goes to sleep, i wake it up and still see wifi connected. so no issues there for me.
Wildmonk has some kernel just to address the WiFi issues.
I suggest WM kernel with CM ROM anyway
The problem occurs randomly. Sometimes my phone "knows" it should turn the wi-fi off when it's locked. But most of the time it doesn't...
I think I will live with it.
Anyway. Thanks for the reply.
My WiFi still disconnects every few minutes, then re connects again. It drives me nuts. Cyanogen 6.0
to momomok,
I think you have misunderstood the word "sleep" for Wifi, here sleep means when you are not using your phone the Wifi will turn off temporarily instead of infinitely. It's more like a nap. As you unlock the phone, Wifi will get awake. That's why you will see it re-appear after a few seconds.
Is there a way to keep Wifi always on, even when Gtab goes to sleep? I have CM7, and have set it to stay on. Still Sleeps. have downloaded 3 apps from market, none keep the Wifi connection on. Any ideas?
Hi everyone,
I'm having a strange problem with my auto sync for my accounts: it seems to turn off randomly. I sometimes use the power saving mode, but when I check it, it does not, at least immediately, turn off auto sync. It's possible that it turns off auto sync if the batty gets low, but maybe it doesn't turn it back on? I also have sleep mode (I.e. "turn off data connections during long periods of activity") checked. It's very frustrating because I never know if its on or off without checking settings. So I end up missing emails which is kind of annoying.
bumping this up. Thought this may just be the result of the "power saver" feature, but it still happened when I turned my phone off overnight. Woke up, powered phone on, and auto sync was off
Hi!
Having troubles with a 520 because once it enters the deep sleep state, it'll start getting Whatsapp notifications only when waking it up.
No battery saving setting is turned on.
An APP that wakes the device from time to time would help.
Thanks.
Perhaps you either have cellular data turned off, have no data signal, or are set to only receive notifications over WiFi? By default, WP turns off WiFi when the screen is off and the phone isn't plugged in. I think there might be an option to change that, but I don't recall where it would be.
There are definitely apps that will cause WiFi to stay on in the background (I think pretty much any streaming music app does this?), but those will wreck the battery life if you just leave them on all day. Apps are also able to periodically (~every 30 minutes) do some stuff in the background even in the phone is sleeping, but I'm not sure if this is allowed to wake up the WiFi and cause it to connect.
If the problem isn't WiFi instead of cellular data, I really don't know what's going on.
Thanks! Read here if you're still interested:
