WiFi shouting off when nt goes to sleep - Barnes & Noble Nook Tablet

For some reason when my nt goes to sleep my WiFi shuts off, I have it set up to never shut off but it still does. Its not really a big deal, but causes a problem when downloading files, I've also noticed when im downloading torrents the wifi shuts off and restarts but not that much any suggestions on how to fix this would be much appreciated. I'm running cm10 thanks

Not sure if dev has kept it as turn off, but there was issue of huge battery drain with it turned on. It wasn't entering deep sleep. Kernel problem I think

You can set wifi to 'never sleep when plugged in'.

I have it set to never sleep

Root chip kills wifi system
Please forgive a noob for being in the wrong place...if, in fact, I am.
Bought five nook tablets for four grandkids and self.
Got a root chip from Amazon:
Nook & Android - 4GB Micro SD Card for Nook Tablet Model BNTV250/BNTV250a
Put it in mine........worked JUST FINE.
Downloaded apps, good wifi on home net.
Got wifi on friends home net and at McDucks, etc.
A week later.......NO WIFI
And.......going to: settings/wireless and networks/wifi settings/.......ALL the options are "greyed out"
( yes, battery is 100%, even does it plugged in )
Threw it in a drawer for a month. Battery went to zero.
Charged it up yesterday. Flashed into Jelly Bean this morning.......WORKED FINE....WIFI CONNECTED.
This afternoon........nothing......back to the s/w&n/w/s...all greyed out.
Any hope....or is it just an Angry Birds toy for the neighbor kid ?
( I got the last EE degree in the US that studied vacuum tubes, and haven't the foggiest idea about partitioning, development, yadda-yadda )

Which version of JB ROM did you flashed?
Did you flashed it onto the SDcard or on the NT internal memory?

Well........it has to be the SD card with the root program on it to get to JB, doesn't it? That is the ONLY WAY to get to the web on the nook, isn't it ?
(sorry....I'm not trying to be smart-a** ..... just that, in the Nook OS, you can't do ANYTHING )
I have no clue what version of JB it is.........didn't even know it was going TO BE JB, when I got it.

I had Go Launcher's battery app installed, and noticed that it has settings for shutting off Wi-Fi when idle. I removed the app and think my problem with dropped wi-fi went away. If you have the Go Power Master battery app (or a similar app), take a look in its settings.

Different ROMS have different issues. That's why more info was needed. This is an outdated ROM and I would suggest you make a new bootable sd-crad with CM10 instead and see if you have better success with that.
Don't buy a pre-made, make it yourself.
Follow this guide and all you HAVE TO do is download an image and burn it to a card. You may WANT TO increase the storage partition as well, but that's really easy.

Edit: I'm a little bit confuses now that I read back. You say you run JB from the card. The data you gave (CM7.2) isn't JB.
Also an additional question: What happens when you remove the card and boot? Is wifi fine or still acting up?

CM7 (including CM7.2) for the Nook Tablet had a relatively very short development life-span and as such still had some unresolved bugs/issues by the time its development stopped -- including some wifi-related issues (see for example http://forum.xda-developers.com/showthread.php?p=23591839&highlight=wifi#post23591839 and http://iamafanof.wordpress.com/2012/06/12/cm7-2-rc1-build-20120612/#comments).

I agree you should upgrade to imafanof 10.1 image

I used image from here using win32to write to 16gb sd and mini tool partition to extend fat32 and very easy and works great with no issues of any kind. wifi setup a little different is only difference but more features and fun with Jelly Bean.
just follow his guide and you'll be glad. I always use sandisk class 4 for boot sd's.

[krn.module] Disable wifi power saving for Dell Streak 360 stock ROM

This wifi driver kernel module "disables" the wifi maximum power management during screen off. The level 2 driver adds it further, changing power saving to off, while on battery power. Hopefully it could increase the wireless strength -- I am testing it.
DISCLAIMER: I am not responsible for any damage caused by the updated kernel module, neither its compatibility. I don't think it would work for any other ROM other than stock 360. Also, make sure you had the bcm4325 wifi instead of bcm4329.
Use at your own risk, always do nandroid backups
To update, either use ClockworkMod or StreakMod recovery, and use any of the attached zip file as update.zip.
Alternatively, you can just replace the /system/lib/modules/dhd.ko and reboot the system.
PS: Thanks to Myshkinbob's hint on http://forum.xda-developers.com/showthread.php?t=752856
WOW , while i was playing with the cifs another wonder came, i do confirm the cifs module works perfect [on 360], am on the process of testing these modules too, streak-custom-ROM-cooks i appeal you to include these modules in your 2.2 based ROMs.
Thank you again !!!

Wifi streaming is now working flawlessly with screen turned off. The no power saving configuration on battery doesn't seems to improve the signal much. But it doesn't seems to have any significant increase on battery usage, so I suggest to just go for the level 2 version.
Gonna ask the obvious before someone else does
setting wifi sleep to 'never' doesnt accomplish what you want? What happens exactly if you set it to 'never' without loading your module? Is it as described in your link where it goes down to ~100kb/s link speed?
Wonder if porting to another kernel is as simple as using it's matching config.gz like with tun.ko or cifs.ko(?)

No it doesn't -- it is unrelated, actually. The bandwidh limit imposed by maximum power saving is much less than the required bandwidh for streaming FLAC audio. The result is intermittent audio playback with repeating 2-5 seconds silence and audio pattern.
Not to mention that I occasionally experiences IM+ Google Talk, YM, and Jabber session disconnects due to the same problem
Whoops sorry double posted

I haven't personally tried Gingerbread on my Streak. Probably will never do so due to reasons I won't post here.

I believe an app could also prevent wifi to enter max power saving mode on screen off. But to make sure it does, then you have to try streaming some lossless audio with it
I'd be willing to help, but have decided to forego gingerbread for now. One too many random reboots. However I'll help you out as much as I can for the good of the masses.

As you're not currently running 2.3 then I assume you're not in hurry for this. We can schedule it later then
Anyway I don't think many people needs this tweak, so let's just take it easy. Just post back when you're ready with a Streak running 2.3.
Sorry but I should've been able to do this by myself if I had 2.3 installed on my phone. But as stated, I don't have any plan for that

I'm back on the gingerbread bandwagon, however I am having wifi issues and I wonder if your fix can help. Randomly, but quite regularly, the wifi still shows as connected, however there is no data throughput. I'm wondering if it possible that the wifi "power down" is going to low and then not powering back up when the screen comes back on. Would your fix help with that at all? If so, I'm ready to help with it for gingerbread.
can u make one for 354? thanks

Raz-or,have you tried putting the 360 update.pkg on your root sd card,then run your phone through the qdl tool......after that....start your phone up in stock recovery,and it will install the 360 you put on sd,then upon reboot go back into stock recovery and do a factory reset......after your up and running,wifi should be working now.after doing this....you could put streakmod recovery on....so you can go back in and do a nandroid backup,and be able to do other things it can do

[cm7] internal build issues to date

I've been playing around with cm7 since release, internal build so I haven't run into the brick problem, but I have noticed a couple issues that I never had with a plain 1.4.0 rooted nook tablet.
First, I am losing wifi connectivity when I let the tablet sleep for more than a few minutes. Wifi will remain on, but just scans indefinitely while finding no networks. Sometimes I have to toggle wifi off and on several times before it starts working again. I have never had it lose connectivity while it was active and doing something, only when I set it down for several minutes and then wake it up.
Secondly the youtube app has locked up my tablet requiring a reboot several times. Sometimes this happens on the first video played, sometimes I can get up to 4 or 5 before the screen just goes black and all input is ignored. I would have left this info on the alpha release thread, but I can't post there yet and wanted to pass this info along. I'm having a great time fooling around with it, and so far these are the only issues I've noticed.
I haven't had the wi-fi isses that I've noticed. Only things I've ran into are those already being discussed in the dev forum - the near-brick experience and larger apps not installing.
In spite of almost bricking, I've still been using the alpha over the last couple days and am definitely loving the freedom and speed over stock. Can't wait to see how awesome it becomes with further development.
The wifi issue can be fixed by adjusting the settings. You just need to turn off wifi sleep. I think this is a long time cm7 bug and not unique to this build. I have reverted to stock for now so I can't guide you through it, but I am pretty sure it's an easy adjustment. (I couldn't go without hulu while in the middle of watching a series.)

Yep, you just go to Settings -> Wireless & Networks -> WiFi Settings then press the menu button. This brings up a small menu bar with two options. Tap "Advanced" and you can change your wifi sleep policy there.

I believe the brick issue is in both the internal and SD release. Be sure to stay away from that SD card format button.

Yeah, I'm not sure where the misconception that it's the SD-Card version causing the problem, unless it's just confusion because the problem was cause by an SDCard Format....I think the issue occurs in either, and I know for sure the internal is succeptible to it, because mine is internal and I was an early-bricker.
Ok, my fault for not being clear I guess. I have no conceivable reason to format an sd-card from within the cm7 alpha release so I have continued using it. Turning wifi to always on seems to have fixed my wifi issues, with a negative impact on battery life.
Youtube is still crashing my NT with regularity but that probably has something to do with the generally bad video performance.

CM7 beta bug report
Hello, I can't post to the development forum yet, but I thought the devs working on the next CM7 release for the NT should know about a potential bug. Also, I've only began using an android device about a month ago, so please forgive any noobish remarks. If after reading this, someone thinks it's important for the upcoming CM7 build release, please let someone on the development team know. Thanks.
I've been using an internal install of the beta build since it was released yesterday morning.
Everything has been working, very well, and I haven't been attempting to format sd cards from the device.
I've had one crash of ADW launcher when trying to add a playlist through the music player widget. I had a minor wifi hiccup that required toggling the wifi on and off to resolve. And a crash of the notification bar, when I attempted to click on an email notification message, which resolved by itself, seconds later.
The bug I'm most concerned about happened just about an hour ago. I noticed the battery getting low, so i plugged it in, powered on. It started charging, so i left it alone, a little while later, I looked at it, and the "n" on the charger had changed from orange to green, indicating a full charge. I awoke the nook from sleep to find that it was no longer charging, but that the battery was only about half charged. I unplugged it, and plugged it back in, but the status light was orange for only a second, before changing back to green, and no more charging.
I powered it off, and plugged it it (which of course made it turn back on /facepalm), but then powered it down through the power console as soon as CM7 booted. I has been powered off, and as far as i can tell charging normally, as indicated by the orange status of the charger's indicator. I intend to leave it powered off, and charging, until such time as the charging indicator turns green.
There may be some information here that is valuable to the Developers and you have attempted to articulate everything well.
However, is there some reason you chose to create a new thread instead of posting your issue In This One?
Perhaps the moderators can combine these threads but I'm sure the developers are more apt to look in one thread then trying to chase down multiple ones.
Good luck with your issues.
Aw crud. Totally didn't see that thread. If a mod could please combine, it would be appreciated.
Maybe the bug thread should be stickied?

I've been having crashing/force closes trying to stream video from sites like youtube.....but with a more mature content....if you know what I mean.
If I'm being too obscure....basically I can't stream porn onto it. Which, imo, is a device-killing bug!
(not really)
On the plus side, it seems like it charges pretty well through a USB connection now, where, if I'm not mistaken, it would not do so on stock. Although I only had stock for like 3 hours before zerging it, so I can't compare it very well....
I was also sitting up waiting on the release of this and have been running it every since then. the only real bugs I have seen is the unable to install alot of apps from the market as it gives the cant write to sdcard which is documented in the dev forums. my wireless does not seem to drain my battery much at all but the device itself never wanted to go into sleep mode unless I forced it into sleep. I changed the screen timeout and changed it right back and the issue resolved itself. Wireless does commonly go from full signal to 2 bars though but even when at 2 bars the connection seems fine and no loss of speed. as far as apps over 20 meg. the only ones I tried I had the apk file stored on my sd card and installed from there and they all installed just fine.
the device seems way more responsive now and I am absolutely loving it although i do miss the nook reader app itself and the one I downloaded from the market gives ab internal error : exception executing the command when I try and sign in Cant wait for the next release alpha or beta I would love to test it.

Go to the "Nook" folder on your sd card, then delete it. then try to sign in on the nook reader. This has worked for others who now have the nook app up and running on cm7

Mostly I'm seeing the occasional app not installing. Every time it has been because "sdcard is not mounted". Even though it obviously it mounted. Aldiko reader is my current villain in this regard. No Wireless problems, but I changed the advanced settings right away. Interface is nice and fast.
Does anyone have any problems with installing games like need for speed

CM9 and wifi dropping

I installed CM9 alpha 0.03 and the wifi will not stay connected. The routers that worked perfectly with CM7 will not work with CM9, anyone else had/having trouble with wifi when using CM9?
Yes!! I had the same issue when I loaded it last night. went back to cm7 till the 3.0 kernal comes out.
Really, I haven't had this problem at all. Try turning the router. Also what wifi security type is it?
Sent from my Team A CM9 Alpha 0.03 Nook Tablet
I rebooted the NT a couple times and so far (2 hours) the wifi is working as it should. I have been using this at work on two wireless routers and I'll be trying it at home soon. I'll keep my fingers crossed, I hope the wifi problem was temporary. I'm loving CM9 otherwise.
Edit: The wifi security is WPA2.
One little update on my wifi problem. The wifi was working perfectly at work and at home until I ran an app that needed the sd card mounted (I figured it was mounted at boot but it wasn't) so I removed/replaced the sd card and bam, the wifi stopped working. I repeated this 5 times, same result every time, so I need to find out what is causing this problem.
I'm having the same problem. My wifi drops out when I run certain apps. For me, it's dropped out when running Gmail or any mail app, and BBC World News app so far.
This was not a problem at all until I changed my email passwords. Probably a coincidence but it happened at the exact same time.
I'd just like to give an update to say that this randomly stopped happening as randomly as it started. I've no idea what the cause is.

I am also having a problem. I am running CM9 externally and my wifi was working great until one day it just would not turn on. I tried rebooting it to no avail. Wifi still works in CM7 and stock ROM. Anybody have an idea to fix it? Thanks.
External is susceptible to getting corrupted. I would backup by TiB folder first... then I would just reformat the card ( sdformatter 3.1 ) and re make it. Hey, try Jelly Bean !

"Android OS" battery drain, any solution?

Hello everyone,
I have big problems with battery drain! When I look into battery in settings I see Android OS causing huge battery drain. I am on stock Ics, tried many things - rooting, changing kernel, uninstalling bloatware with Titanium, changing baseband ... Nothing seems to help! I've realized that Android OS is active while WiFi on... When I switch off WiFi, battery life gets very good (or normal) and Android OS stop draining the battery.
Does somebody have same issue or knows THE solution? Except putting CM9 or other non stock Rom, would like ti keep Sony's Rom.
P.s. My girlfriend's Xperia Ray has the exact same problem!?!

WiFi on always eats far more battery than WiFi off.
If you've turned off all synchronizations already then it's just purely the constant search for the WiFi network and back and forth polling needed to maintain the connection being handled by the Android OS that's eating your battery and I'm afraid that would be perfectly normal then and not something one can fix.

WiFi on always eats far more battery than WiFi off.
If you've turned off all synchronizations already then it's just purely the constant search for the WiFi network and back and forth polling needed to maintain the connection being handled by the Android OS that's eating your battery and I'm afraid that would be perfectly normal then and not something one can fix.

Of course, but as you can see in the post above, what is strange is that when I was out of home (the first 3 hours) with wifi on the battery was doing fine even that the phone was probably searching networks all the time, and since I returned home (last 3-4h) the battery drain started again...
Shouldn't it be opposite? When connected to home wifi it should stop searching for it. So it's probably a sync problem, but whatever I don (Sync on or off) it's the same...
Could also be a clash with your router.....
Try changing channel see if that helps, if not you may be stuck with it or go back to gb

good idea! I'll try it, hope it works...
Get BetterBatteryStats somewhere from XDA (google it) start the app, leave your phone for a few hours and then go back into the app, press the settings key on your phone and choose dump to file. A .txt file will appear in the root of your sd card, attach the file to a post. Hope I can help

here it is, but seems have worked only 7h, while I was not home connected to Wi-Fi , so I'll post once more tomorrow...
Well judging by this it might actually be normal for android os to consume as much battery, because you haven't really used your phone much. The battery drain you are seeing on the battery settings is simply android os is draining the most out of your phone relative to other processes using much less.

Thanks to everybody, especially @mpiekp! Finally it seems that Wi-Fi router channel was the problem, since I changed it Android OS stopped, I can see in battery stats that it wasn't active since. The same for my girlfriend's Xperia Ray!
I'll be checking it from time to time in the next couple of days, just to be sure...
I love XDA!

[Q] Wifi turns off during sleep.

So whats happening is, im streaming pandora or spotify and the music just shuts off about a minute after the screen does. And when i turn the screen on the wifi icon at the bottom right is blank for a few seconds, then turns grey, then blue and the music starts again.
I have checked the option to never turn off wifi and installed wifi keep alive, and tried regpon keep alive but neither are working. I've also been through all the power options and unchecked anything that would suspend my network connection.
I know its not a router issue because I'm getting full bars and everything is fine as long as the screen is active and my other devices do not lose internet connection.
I'm also not using a Dongle. Any ideas?

Do you get the same results with a charger plugged in?

Yes I did.
Unless there is something non standard about the TFP there would be no reason that your streaming apps couldn't retain a WiFi lock - Android programmers guide here http://developer.android.com/guide/topics/media/mediaplayer.html.
If a program such as regpon is needed then I see that regpon was last updated January 2011 - is it worth trying some other apps?

I've had this same problem, and it started after the Jelly Bean firmware update. Doing a factory reset didn't help. I tried contacting ASUS' service department, but they sent me back a boiler plate response just telling me to do another factory reset. As far as I'm concerned, the tablet was broken by the update. It's pretty much useless for any task that doesn't involve the active use necessary to keep the screen awake. I'm going to try calling ASUS this weekend when I have time to sit on the phone, but I don't expect much. At this point I doubt its something I could fix myself (unless I root the thing and spend time poking around for whatever hidden setting is forcing wifi off during sleep) and am resigned to the tablet being broken baring some patch from ASUS.
I've seen some similar reports from other devices too though. Yet not a single solution other than trying those two apps (which didn't work for me either). I don't know if its ASUS' particular Jelly Bean setup or a more general Jelly Bean bug.
My wifi's turning off while the tablet sleeps as well. It's really annoying; hope Asus figures out some sort of solution for this.

Thanks for the info. I did notice the problem after the jellybean update. I also just did a factory reset twice to try and fix the issue to no avail. Hopefully Asus rolls out a firmware update soon.

Go to wifi settings. Hit the menu and go to advanced. Uncheck the box to disable wifi on sleep. Its a little tricky with JB as the menu button is up at the top. It should look like 3 little dots sacked vertically.

Although I appreciate your help, the problem isn't that we haven't set Wifi to stay on during sleep (or unset an option for it to be disabled during sleep). The problem is that our configuration choices are being wholly ignored or overridden by some setting we can't see. For example, my Wifi Advanced Settings is missing two of the settings that are visible in the screenshot you've posted. I've included what I see. I've also included a shot of the ASUS Customized Settings menu which also has a wifi use during sleep option.
The Wifi Timeout option on your screenshot has caught me eye though. It seems like there is something hidden on my tablet (and the others experiencing this problem) that is similar to that option. Again, this wasn't a problem for me before the Jelly Bean upgrade. Setting Wifi to always stay on during sleep under ICS worked just fine.

My WiFi goes to sleep as well.
As the others I enabled all the settings to keep WiFi on.
Wondering if anyone has had any traction on getting this issue isolated or resolved. I have come across the same Wi-Fi sleep problem.
Thanks

I don't want to speak too soon, but the latest update seems to have fixed things for me. The patch notes mentioned that they adjusted the wifi configuration to recognize Chinese characters. Maybe the changes they made also corrected our problem. I'm also on my family's router while home fpr the holidays. I'd read that some users in JB regaedless of their device were having this problem with older routers.
I am curious to here if it is resolved for you. I have done the JB update to 10.4.2.18 which had that fix and I still see this problem. In addition it happens on any network I connect to so I don't think the issue is there.
Thanks
Did you change the setting to WiFi on always during sleep?

shouldnt have to. a streaming app should keep the wifi alive.
I've tested my tablet with all the posted setting set to keep WiFi on during sleep while streaming Pandora and it works fine. I let my Prime sleep for over 10 minutes without interuption. I don't know if this makes a difference but I am docked and using the Pandora app not streaming through my browser (Boat). I then set my Prime to shut off WiFi at sleep and Pandora (on the app) kept straming until Pandora timed out. Strange indeed.
I'm on 10.4.2.18 not unlocked or rooted.

Noob here.......
I saw this post and have just run into this problem myself.
When my tablet screen sleeps, my alarm apps won't work, and none of my mail gets pushed UNLESS I have it charging.
Why does this happen, and is there a work around? I've designated my wifi to never sleep/always be on.
I'm using an Onda v972.
I had a rooted Nook Color, and this never happened with that. Same programs.
Thanks for your input.
solved it
I have solved it I have same problem on my tablet and I fix it by downloading an app called WiFi advance Locke
Skype Notification Problem
Hi,
Has this problem been resolved? When the tablet goes to sleep Skype notifications no longer sound.
I keep the Skype app running in the background at all times. WiFi is set to not disable.
Any help appreciated.
