I am troubleshooting the SOD issue, and was wondering if anyone is / has been experiencing this problem when NOT using bluetooth (you get SOD when your bluetooth is turned off)?
In the meantime I am checking to see if auto updates set to "on" in Facebook / Twitter / or Weather could be the culprits.

sorry mmicha - when I was getting the sod I changed roms until I found a version without a problem. recently I've used roms with sys builds 23541 and 28232 running bluetooth as well as auto updates without any problems.
I once had the SOD with using bluetooth a while back (when paired with a rental car's BT stereo), but yesterday started getting it every time phone goes to standby (without using BT) - only soft reset/removing battery helps. I have made no changes to registry or even installed apps in the last couple of weeks so have no idea why it is happening. Continuing to search forums at the mo...
BTW: Stock 6.5 WWE ROM
SOLVED: Turns out it was SRS WOW HD causing the SOD as no had it once since uninstalling. It was strange as I had installed it days/week prior and the SOD just happened suddenly when I hadn't even used SRS or my music player at all that day!?
I've been having a problem on all of the recent nightlies, and i know lots of people are having the same problem on the CM6 RC2, where turning off the screen puts the wifi to sleep, even when you have the wifi sleep policy set to "Never".
I noticed this when i started trying to stream music from Grooveshark or Subsonic- if i turn the screen off, the song stops a few seconds later, presumable because it has run out of buffer.
Is anyone else still having the same problem? Does anyone have a workaround for this?
edit: it seems to have no problem staying awake on my home network, but my work network is where i have the problem- could it be something about the wifi network that is doing this?
well, strike that- i'm encountering the same problem on the 2.2 stock rooted ROM as well. it appears to be a problem with the wireless network here at work.
I might have left my phone screen on at home, which would have let everything buffer, preventing me from noticing the problem there, but i'm pretty sure the wifi sleep policy works correctly on my home network. Very strange.
This is easily reproducible for me as well and only started happening with CM6.
for me this happens on every rom, even stock. there has not been a day i've gone to bed and woken up 8hrs later with my wifi on.

I'm glad I'm not the only one- though it seems to happen more to N1 owners, it seems this is happening to android users all over the place. From everything I've read today, no one can figure what causes it- there's no rhyme or reason to it. For me, the wifi sleep policy works correctly on my home network, but not my work one.
I read a post from a week ago somewhere that there was a fix coming from broadcom (those are the same people that are responsible for my router's wireless N problems with DD-WRT), but I don't know if that was referring to a Nexus One specific fix or a fix for all android phones.
I'm glad at least my wifi sleep policy works correctly at home, but the fact that, for some reason it doesn't work on a different network is extremely annoying.
Does anyone else have issues with the WiFi connection while the screen is turned off? I noticed that not a single one of my music streaming / radio apps work when the screen isn't on. It works for maybe a minute before all sound just stops. Starts just fine again once I power up the screen.
Has there been any changes done to the handling of these matters in ICS perhaps?
Pretty annoying not being able to stream music over WiFi as I think I'll hit my 5GB limit on data pretty fast if I can't use the WiFi at work for this.
So has anyone else noticed these issues?

Yeah same here. I remember this being an issue with Android 2.1 for my Desire but was fixed in custom roms. Might be the same situation here again.
I remember this being an issue with my Nexus One, don't remember if it was fixed in 2.2 or 2.3. I remember testing file transfer using SwiFTP, with the bug the file transfer would go down to double digits (kB/sec), with the bug fix it would be a few hundred kB/sec, with the screen on it would hit mB/sec or so (in any Android version).
I believe this is the official issue:
http://code.google.com/p/android/issues/detail?id=9781
With my Nexus S I'm not experiencing this bug. Sscreen on still gives me a major wifi speed boost, but screen off I get a few hundred kB/sec, which should be more than enough for any streaming app. KiloBYTES btw, not bits. I'm surprised ICS and/or Galaxy Nexus brought this problem back. Or it could be something else entirely.
Are you connected via 2.4GHz or 5GHz wifi? I would think the new 5GHz radio in the GN probably has more aggressive power saving features. Try switching to 802.11b/g (instead of 802.11n, in any frequency), see if it helps.
Have you changed your WIFI sleep policy?
On my Froyo phone, if you hit menu while in the WIFI settings (I know there is no menu in ICS) you get an option to go into advanced settings where you have the option to choose your WiFi sleep policy (When screen turns off, never when plugged in, never).
There should be a way to access that advanced settings area somewhere.. My phone is a couple hundred miles away right now and I won't see it for another week so I can't be of much further help right now. However, there "was" a setting in previous versions.
best info at the time last year was here for the N1
http://www.google.com/support/forum/p/android/thread?tid=01a47ff5b0a92d52&hl=en
7xx replies there to read, but really good info. somewhere in there, maybe around#600 the info gets good, can't remember. But shortly around this time the problem was gone/fixed.
there was a guy with an app i think it was wifi fixer, i could be wrong. that worked sometimes, but battery drain was bad. Whatever google, or CM did fixed the low power save mode issue. I'm thinking it was something at the kernel level?
edit, on second thought, there's no good reason to read all that. You won't get a fix out of it anyway. It was updated away in the end, something related to MAC addresses and build numbers and frf50 or some such.
BUT this seems like the same kind of thing going on in the power save mode.
Have you checked your advanced settings?
Wi-Fi>>(settings [bottom right])>>Advanced>>Keep Wi-Fi on during sleep...
Mine was set to always by default, so I suspect that the issue lies else where...

Same here. Mine was set to always by default but still getting this issue.

I would suggest that this issue is related to the individual applications you are using, rather than anything to do with Android.
I am able to stream music from Google Music via WiFi just fine when the screen is off, and I am also able to talk to someone on Skype via WiFi just fine when the screen is off.

Thanks for posting that; I was getting pretty worried and disappointed after reading this thread. I had to deal with this when I first got my Nexus One, until Google released the 2.2.1 update with a new Broadcom driver which finally fixed the issue. No streaming, no pushes, just nothing at all from wifi when the phone went to sleep. All traffic to/from the phone would just stop. It was maddening.
The Galaxy Nexus comes to Canada a week from today, and this would've been a show-stopper for me. At least it's working for you, so my day isn't ruined quite yet
Has this issue ever been nailed down? I've seen considerable discussion on it going back years. I've seen considerable speculation regarding WIFI mode and Governor. I've seem many of the bug reports marked closed.
Yet I have a GN on v4.0.4 and the moment the screen goes off - either because you turn it off or it just times out - the WIFI goes to h*ll. I've run ping and network trace from both sides and there is no doubt the WIFI stays connected, however latency goes way up and packets are lost... and with TCP connections it gets congested with retransmits. I've run with the governor set to "Performance" and there is no difference.
So, is there any consensus on what is causing this problem with current stock hardware/software?
I read that it's something that's been coded in for a while. Try using this:

Ok, to answer my own question, this is still related to the PSP issue from years ago:
code.google.com/p/android/issues/detail?id=9781
code.google.com/p/android/issues/detail?id=15549
Bottom line is that some hardware - like GN - has an additional level of PSP on WIFI. The issue was resolved by inclusion of an additional lock mode - WIFI_MODE_FULL_HIGH_PERF - some time ago. However, its up to an application to request the new lock state if it thinks it needs it. Many don't.
So, its probably not a bad idea to contact developers of the various applications and recommend they look into the new lock level in the later APIs.
Also, the "WIFI High Performance Widget" can be used to manually hold a WIFI_MODE_FULL_HIGH_PERF lock on the WIFI if you're dealing with an application that isn't doing it its self. Beware of the other "WIFI fixes" out there, none of the ones I tested were acquiring the correct lock.
Also, from an adb shell you can use "dumpsys wifi" to see who is holding what lock, for example:
Code:
Locks acquired: 5 full, 5 full high perf, 5 scan
Locks released: 4 full, 4 full high perf, 5 scan
Locks held:
WifiLock{PANDORA type=1 [email protected]}
WifiLock{HighPerformance type=3 [email protected]}
Here you can see Pandora is only holding type=1 (WIFI_MODE_FULL) and HighPerformance is holding type=3 (WIFI_MODE_FULL_HIGH_PERF). Dumping the WIFI state takes the guess work out of it.
Tried that widget, having absolutely no luck with 'in tune' and 'winamp' for radio with the galaxy nexus verizon...
as soon as the device sleeps, wifi goes to hell and buffer drops in and out every 2 seconds. Completely unusable, any recent fixes? this is totally making me think I just bought a $400 brick since this feature was very important for me.
What may be confusing about that widget is that it is a "widget". You have to locate it under "widgets" and then put it on the surface and then click it to enable it... it should be blue when on, and black when its not.

I have been trying to put the 'widget' itself (2x2 square) on the home screen but even if i hold and drag it to where I want it, it never actually appears on the screen. And of course i'm still getting crazy ping times...Does anyone else have this working on a GN (verizon - not that it should make a difference)?
I have found a few workarounds to this issue, none are great and frustrate me greatly.
1. Root and use the franco kernel. Seems people with that have no issues - since you can set? the wifi to full performance.
2. Use this wifi performance widget
3. Use an app that has properly set its own wifi settings. - Going through all the radio apps on the google market, i am finding only one app that seems to be doing this right: DI Radio - some kind of dance/techno/etc - confirmed it with ping times, they remain low on sleep.
Not one other radio app seems to have set 'proper' settings - which shows that something needs to be addressed in the os...I was having good luck with the yahoo music app, but depended on the stream (maybe some buffer more :dunno - the ping results are garbage.
EDIT: I tried installing high performance wifi again, and finally got the widget to one of the homescreens! Let me break it down for anyone else who comes across this. After install, the small 1x1 blue app box is put on your desktop and the black screen comes up with the wireless networks and a checkbox. I then went to apps->widgets and tried putting the 2x2 widget on the home screen again, and like always it clicks on like its there (and when you click home and its never there). However, this time I hit BACK instead of home after dropping the widget and it took me back to the black screen with the checkbox, then i hit home and voila its sitting there. You can click on it like you mentioned! Confirmed with ping for tune in...pings remain low.
If this continues to work, it may be a godsend. It is annoying having to have this, but far far better than not.
I had that problem also especially when i tried to download big files when the screen turn off the download speed became extremely slow, this widget solve this, i think to that moment its the easiest solution tap it when you need it tap it again when you done.
By the way i had this problems with franko kernel also and again to my opinion it is the good solution for now, until the apps developers update their apps.

If you download the SDK - you only need Android SDK Platform-tools - to a PC and use the adb shell it is easy to dump the WiFi lock state with dumpsys wifi and see exactly which app(s) are holding what locks. Completely takes all of the guessing out of who is doing what when. Judging the behavior can be subjective because there are other reasons that the WiFi can break up which can be very frustrating.

The app does work well, however I have been running into some issues as I continue to use it. It randomly decides to turn off the forced max wifi (even though its still blue and looks like its operating) or perhaps the phone is forcing the wifi issue again. It seems to happen when you are downloading, playing with some other apps? You only notice it when you sleep it and the streaming radio immediately starts having issues.
Solution is to flip back to the widget turn it off and turn it on again. It works, but is another annoyance.
I haven't yet ascertained exactly what causes it to switch off yet.

I will look into this, thank you.
---------- Post added at 06:16 PM ---------- Previous post was at 05:28 PM ----------
I used the adb shell (learned how to install all these dev tools and how to use it first ) and here is some updated info:
Tunein = type=1
Pandora = type=1
Audioaddict service (Digitally imported app I posted above previously) = type=3
google music = type=3
High performance app = type=3 (havent figured out why this likes to stop randomly)
I will update with more app info, hopefully others can also email the developers and see that it gets fixed, so we no longer have to use damn workarounds...

Yes, it definitely has an issue holding its lock, and it definitely seems related to another application taking over and also when it switches to cell and back, I can confirm that. It may be related to the OS since the widget thinks it still on when clearly the lock as been released, so it may be that the OS released the lock and the widget has no idea. I haven't taken the time to look into the details yet, and this is something we should make the developer aware of.

Yup, from what I can see it loses lock:
1. when cell switching
2. manually killing/starting wifi
3. when ANY application is downloaded/removed (ie. changes in permissions)
4. when playing with dolphin, other apps for more than a few minutes, it will kill it even though the blue stays lit. I think its as you mentioned, during general use of the phone, at some point some permissions are changed and hifi performance is tossed off its lock.
If you only are streaming music and re enter the phone to check a gmail alert or two...it seems to be fine. otherwise you need to hit the lock widget one more time before sending it to sleep with pandora/tune in playing.
So yeah, I have been noticing that my Desire running on the latest MildWild software (and Cyanogenmod 7.2) for that matter has been trouble keeping it's connection constant on Whatsapp.
Basically, it stops 'reporting' when it comes to 'last seen'. Sometimes I have to turn off Wifi (It is mostly on Wifi, can't recall it being the same story on 3G but I think so too) to fix the connection. Other times it just reconnects after a minute.
This happens when the screen is turned off and back on.
It's getting a kind of annoying and I have no idea where to look. I've checked my modem and router and both are fine.
Anyone else with this problem? Any ideas how I can fix this? Also, Wifi Sleep Policy has been set to 'Never'.
the same galaxy s3

Hi folks, I was wondering if anyone could help me out
I've noticed on my HTC 10 that I had a lot of downloads just disappearing, these download don't complete and don't fail they just go missing while in the middle of downloading. I have noticed that when the screen is on they seem to complete fine but when I switch the screen off they are just gone and I have no idea why this is happening, I've googled to see if it is a known problem but I've had no look. I'm totally stock and use chrome browser (if that helps).
Cheers RR
Is your WiFi set to turn off when the screen goes off? Check under WiFi advanced setting. Also you could disable WiFi optimisation.
It's because your internet connection is cut off.
It is only when downloading items though, I still receive notifications from facebook, emails, twitter etc. I will check my settings but I'm sure that's not it.
edit:
Wifi is set NOT to go to sleep when screen is off and optimisation was on will turn off and test.
Edit 2
Wifi optimisation turned off and download still disappears
The problem is chrome related
