[Q] Wifi dropping after phone sleeps for a bit. - Droid Incredible Q&A, Help & Troubleshooting

My phone seems to not be able to keep wifi connectivity on CM6. It does on Sky Raider however. I tried to enable never sleep in advanced options but it doesn't seem to stick.
I've tried the wifi keep awake app. I was wondering if there was any way to manually set it with something ADB related.

I have the same problem. What I did was just turn the screen to not time out. But I would think there should be another way to where the screen could be off. Hopefully someone will have a suggestion

check in the wifi settings.........menu >advanced.......you can set the wifi to go off for 3 different settings.

I've tried that, it doesn't seem to stick on CM6.

Yes, i have noticed this on mine at work. Will see if it does the same thing at home.
interesting problem can more people confirm?
maybe this is related to this other case? http://forum.xda-developers.com/showthread.php?t=1313800
My guess is it needs to toggle so you can recieve calls. When we get Wi Fi calling then it will be fixed.

yup, mine does this as well. just got it a few days ago. seems like when the screen turns off, the wifi turns off with it. every time I unlock the phone, I see the wifi icon come on and connect automatically. and YES, I have checked the wifi sleep options. wifi is set to NEVER turn off.
Also it sometimes completely disconnects from my router and I have to turn wifi off and on again to reconnect.
hopefully this gets resolved with the next update.
concering the issue if you look in your wifi settings and you see it scanning every 2-3 seconds, would this fix it? i remember a developer had made this adjustment to the buildprop when i owned an optimus V.
Changed wifi supplicant scan interval to 60

data hanging

Hi,
Does anyone have this problem on their phone? Every now and then, when I am doing a data related function, data hangs as though it is not connected even though I am in a perfect 4g coverage area and the 4g sysmbol is still on. I know its hanging because the arrow to the right of the 4g symbol stays lit green. It either starts working 5 minutes later on its own or I turn wifi on and off. I have the newest sim card installed.
Any thoughts?
Thanks
probably a software related issue
the only time i experience that is when i lose connectivity with the network, as in the signal bars or 3G/4G arrows are all greyed
Yea dude i noticed even tho i have wifi set to never it always shuts off or i should say loses connection i hate it because i have to pull down status bar hit it off then on wifi is definitely effed on stock too. Anyone else experiencing this? I know its a problem cuz my g2x i could leave it alobe for an hour in hibernate come back and wifi still good to go anyone have any ideas? Or is it a s2 problem witg wifi cutting off. Like i said the icon will still be there but i wont have connection and 50% of the time i have wifi icon and 4g
Same issue here, in two different phones I've had. Not sure what the issue is. In fact, opening this page, my data was hanging for a minute, irony.

for this issue you can configure how WiFi behaves, but the settings are only accessible via spareparts or custom ROMs
I set my wifi to never sleep while on charger

But this happens to me when my wifi is off. Only on the cellar data connection.
I had this issue after giving juice defender superuser permissions. It seemed that it would not turn data back on when I had the screen on. I'm not sure if this applies to you, but I no longer gave juice defender su and everything was fine. a lot of those functions in that app do not seem to play nicely with this phone yet anyway.

It happens to me several times a day. Usually right after a voice call. I just put on flight mode for a second, switch it off and data is back. I have no idea what's causing this. Always on 4g, wifi is working perfectly.

+1 to everything already mentioned.
I was in Vegas this weekend and had HORRIBLY slow/no data at all. Like has been mentioned, the green arrow with just stay lit. thought i was the rom, i nandroided back to stock, same issue. Hope this is fixed soon it is hella annoying.
This fixed it for me
I have had this same issue for a while, here's how to fix it. Go to Titanium backup, I found out that there're two versions of "My account" on the list, so I frozed the old one, then go to task manager "kill all", the 4G icon will disappear. Open up "My account" again, the 4G reappears but as soon as I close the app, the 4G icon would disappear.
Hope it helps someone
I too have similar problems where my data hangs or doesnt want to connect. Then a few minutes later, it will decide to start working. This happens even in full signal regions. Stock rom and/or BeastMod rom...
Not sure why it happens :S
For those having problems and have tmobile my account on phone freeze it or uninstall it i guarantee it fixes your data problems trust me. I to had problems just like you guys and i was told to uninstall my account i was like what? What the hell is that going to do but believe me when i say it worked! I actually unfroze it to see if the problem would come back (4g and wifi on at same time) or cutting out. And it did. So i refroze my account and bam 4g disapeared while wifi on. This has fixed all my wifi and data problem phone works flawless now! Basically i think t-mobile trying to snoop with our data. Scumbags
This is happening to me. The phone is driving me mad. It happens constantly. The "up arrow" in the 4g icon will light up, and all data will freeze. I stare at loading screens all day long. It freezes anywhere from 30 seconds to 2 minutes. Then it will fix itself, then it will happen again within 2-5 minutes. I'm furious with this phone.
Wifi works great. It's not dependent on my location, it happens no matter where I am. Doesn't matter what I do, nothing prevents it from happening. Of course, the Airplane mode toggle or resetting APNs and all that will do the trick to fix it temporarily, but it will only happen again 5 minutes later.
I'm on stock, unrooted. I am ready to throw this phone at the wall. Has anybody else managed to actually fix it or get a response from Samsung/T-Mobile?
I should have read this thread before buying this phone. This is so annoying. I tried to put the phone in flight mode. It fixed for a min and back to problem.
I'm having the same problem. I didn't have this problem until I updated to 2.3.6. Anyone else still on an earlier version?

Same things been happening to me lately, its awfully annoying. Makes me want to throw my phone across the room sometimes.

[Q] wifi turns off and on when screen is off

In the wifi settings>advanced, I have the wifi set to never sleep, however when I am playing music over the wifi connection, the music starts and stops about every 2 seconds when the screen goes off. Is there a way to make the wifi stay on when the screen goes dark?

I too would like a answer, good question!

I am NO Android Dev but I did run into that same problem that you seem to have with running Cyanogenmod. I did searching around for a week or so and really didn't find anything in particular about the problem.
I do recommend you try, re-flashing the Rom after you do a Nandroid Backup. If you don't want to go that far you can try to set the Wifi to a static I.P. by going to Wifi advanced settings. That was my problem, but there could also be other variables that could be causing your problem.
Let me know if I helped, and respectfully hit that Thanks button if I did anything for you. Good Luck!

Was it the reflashing or the setting the wifi to a static IP that solved your problem?
The only problem with setting my wifi to static would be that it would only work while I was at home. If I am elsewhere where I can't control the router, that probably won't work.
Are any of you using Cyanogenmod as well, or does this issue exist on the stock rom as well?

[FIX] Dropping WIFI (disconnect/reconnect issues)? Check this thread.

I know I had a problem with WIFI dropping every few minutes and disconnecting/reconnecting all the time. Causing streaming issues, internet issues and freeze issues if on lockscreen. Well, I have fixed this for myself and wanted to share.
To insure this doesn't happen, just follow these steps:
1. Dial *#0011#
2. Hit the left menu softkey to bring up the menu, and select 'Wifi'
3. Turn OFF the 'Wifi Power Saving'
4. Exit, and Reboot.
Ever since then, I haven't had issues. I am on AT&T GS3. If you are having this issue, please report back here with your model and if this fix worked.
Just trying to help. Good day all!
I'm not entirely certain this was happening, but had noticed some oddities. Not as bad as your experience, however.
But I did make the change to see how it would affect battery life. I am on the Sprint network.

Didnt notice a difference and after a reboot it turns back on.

I don't have issues at home but I do with the WiFi at work so I'll try it tomorrow and let you know how it works out. It disconnects and reconnects every 5 seconds and I'm not exaggerating either.
I think the WAP may be a little wonky but my HTC Desire HD had no problem with it.
Mine turned back on after reboot as well.

I am working through logcats as well. I reverted the setting to mimic the problem, and I am going to look at logcats.
If I can see what is exactly triggering it, I will make a flashable fix.
In the meantime, I have another S3 here that I have the power save off on and I still haven't seen a drop yet. So preliminary, I think this is a temporary fix until I can find out root problem.
Hope you find a fix

I have a similar problem. Mine doesn't disconnect per-se, however I did notice while browsing through Flipboard that I wasn't getting any signal sometimes when trying to access a page with a lot of content. Page loading came to a stop. Backed out several times and retried until I finally gave up. This was on my home wifi. I'll try your work-around for a few days. T-Mobile version.
EDIT: This may be just a FlipBoard quirk.
I will try this when I get home. I have a problem on my Sprint SGS3 where it stays connected to wifi but the internet won't actually work (can't browse internet, use play store or youtube, etc). Wifi never sleeps, it's always on. It never disconnects from the network, it just stops receiving and sending data. So we'll see if this does anything for it.
you guys dont have an issue where the display doesnt timeout after turning off the power save?
display won't time out from turning off the wifi power save. Totally unrelated. I am trying to mimic the problem right now.
If anyone is having the issues of the reconnnecting every few seconds and can logcat it for me, PM me please. I can't seem to mimic the problem since the fix.

It happens randomly and especially after the phone goes into deep sleep with wifi on

Turning off power save does indeed fix the WiFi issue at work. As posted before, restarting the phone turns power save back on and the problem is back.

PM sent.
Going through multiple logcats now.
I am seeing even with power saving on though, the problem is still there. It is still disconnecting from WIFI and going back to the data network.
I am sifting through ALOT of code, as some of these log cats are extremely long.
Give me til tonight and I should have a reason at least to why it's doing it by comparing on vs off on powersave.
I have a request, anyone WITHOUT this issue, can you send me a logcat with your WIFI turned on?

Thanks for this. I was about to return the phone because I kept losing ability to connect to any WAPs after sleep mode kicked in. Mine is a Verizon S3.
I've seen this as well. Almost always after deep sleep. Most of the time I have to cycle Wifi to get it connected again every so once in awhile it will connect again on its own. Regardless of the settings that I put in "advanced" under wifi it will do this. Even if I have it set to keep alive never, always or plugged in it doesn't matter.
I still need a logcat from someone NOT having these issues.
Right now from looking through over 10 logcats, I am seeing that it's usually happening on routers that are encrypted with WEP and WPA, unfortunately the 2 most popular forms of wireless security.
That being said, users that are on 'open' networks do not seem to be losing access.
2 things.
1. Can someone PM me a logcat of them successfully connecting to wifi and NOT having drops. I don't care how long the logcat is.
2. When you post about your problems, please tell me what carrier and what type of encryption is being used on the router (if any)
I have been comparing and in each instance, WIFI is going into sleep, turning on data, and then having a problem turning back on.
I think it's an attempt to save power, but only it is not because switching from WIFI to data back to WIFI so much is a real drainer.
Still working on maybe disabling the power save by using a init.d script, to prevent power save mode from coming back on when rebooted, because I know alot of users are saying after disabling it, it is just reapplying on reboot.
BACK TO LOGCATS FOR ME. :/

Intermittent Wi-Fi problems

I have this annoying Wi-Fi problem on my Desire. Tried with both CM based and Oxygen based roms, different radios, RILs, kernels etc but still have the same problem.
After a while of using the phone with Wi-Fi turned on while screen is on and then off while screen is off (using 3rd party application to manage this and not wait for the 15min timeout as per default in Android). The Wi-Fi won't connect anymore and won't see any availible networks whatsoever (not just my router but none of the neighbours as well). When turning off wifi and then on again it says "scanning" for about 2 seconds and then "disconnected". Sometimes it works to turn wi-fi on/off a couple of times but often I need to reboot to get the wi-fi to connect again.
I'm running out of ideas to test and can't really believe that this would somehow be a hardware problem since wi-fi for the rest of the time is working perfectly.
Also, I have observed the same problem while turning wi-fi on and off manually before turning off screen etc and thereby eliminating the 3rd party application.
Any ideas?
I would say that the HTC desire wifi signial is sometimes poor due to low cost hardware. There is no going about but I've many seen a fix to that but, try not to put The adaptor behind oblique or thick obscure object as it will intterrupt the signal.:banghead:
Edit.
Try cold reset your phone and s-off and root. Cold reset is full factory wipe. Don't change radios too much, it harms the signal.change hboot.

Thanks for your answer.I have more or less tried everything you mention and I'm s off and rooted since a while back.I don't think this has to do with bad hardware but more likely some kind of software flaw.the problems are totally intermittent and even when I'm 1m away from the router it can happen.
My latest thing is to try with a program that closes Wi-Fi when screen of but at the same time set the android sleep policy to "never".gone a day without any problems now but still to soon to say...
Edit: It's now been 4 days and still not one problem with the Wi-Fi. Perhaps the combination of software that turns on and off the Wi-Fi all the time works best if the Android OS is set to "Never sleep" policy after all...

I have a problem like this before. What i did was to flash another ROM. That solved my problem.
Try miui ics. It's sweet about wifi
Sent from my HTC Desire using xda app-developers app
Since I set android system policy for Wi-Fi to never sleep I've had zero problems. So if people are using programs to shut off Wi-Fi when screen is of etc I recommend using this policy if having Wi-Fi problems.
