SOLVED[Q]Wifi continuously scans even though connected

I am on Legendary 2.1 and just had it pointed out and I verified that even though my wifi is connected to my router it continuously scans every few seconds. This has got to be a battery drain. Is there a way to turn off the scanner when connected or set it for every 5 minutes instead? Thanks.
Edit: Thanks TeamERA for explaining that it only does that while in the listing window so it can update the list immediately. It defaults to the scan interval in build.prop when that window is closed. Thank you.

I think romtoolbox allows you to change that Im not sure but you can check it out.

Sorry root tools by jrummy allows you to change wifi scan intervals

I'm pretty sure you should be able to turn off 'network notification' while connected...this should stop scans since this option is made to notify when a network is available. In theory, if its not notifying you if new networks are available, I would assume it's not scanning. Good luck

I tried SleeperROM and it does it there too. Can someone look into making the scanner manual only?

That would be awesome cuz you have to figure that's a lil bit of a battery drain.

I found a program called wifi buddy on the Android market. This program allows you to disable wifi scanning.

I will try that...thank you! Probably add hours onto my battery life on weekends at home with wifi on.

Wifi buddy settings only control that app not the system settings so disabling wifi scanning only worked inside app not to system wifi scanning

I'm not knowledgable enough yet, but has anyone looked into using SQ Editor? Perhaps something can be manipulated in system files to just disable intermittent scanning all together? Only initial scan when wifi is activated? Just an idea...

That's what I was hoping for. Can't seem to get a DEVs attention to look into this. Build prop edit doesn't do anything.

Trying to find any sort of process or folders in root explorer that relate to wifi/scanning and coming up empty...I'm with you Kenny, we need a dev to pick this up, especially if editing build prop showed no results

I think my phone is doing this too.
In betterbatterystats mmc_delayed_work (under kernel wakelocks) accounts for 90% of my wakelocks, this does not happen on 3G so it is definitely related to Wifi.
I thought it had something to do with my router (DIR-655) as other people said they experienced unusual drain with that router.. Not so sure now.

This is probably the main reason people are complaining about their battery life on the gingerbread builds. I think it is more of a EI22 issue. How did EH17 or the previous gingerbread Roms handle this and if it handled this issue better can we take something from to fix our problem.

It would be nice to actually have the system manipulated, however, I am pretty sure that Juice Defender has an option of wifi control...I think (and I don't fully remember, just went to Thunderhawk and haven't put it back, trying to figure out other ways to better battery, as is everyone else) that you can allow JD to stop all wifi unless user selected.

So I don't claim to be a dev, but I just thought of something that might lead you in the right direction. I remember a post about lowering the signal threshold on your phone to get better 4g connectivity a couple of months ago in the general section. Its a dialer code and you need your msl to gain access. This is one of the phone settings like at the bios level. When I did this, I was able to see a boatload of settings that you would not find anywhere in the os settings. If you know where I am talking about and know the dial code to get in there, I do remember seeing some wifi stuff. Maybe something in there you can change scan or retry rates, with signal thresholds that might work for you. Write down all changes you make if u need to go back.
Again, just a thought trying to help.

The first A100 I bought would not wake up from standby. I had to take it back and get another one. This one has worked fine.

I will give it a few more days. Wish there was a concrete answer on what causes it as almost all honeycomb tabs seem tp be plagued by it. I changed my screen timeout to never and no lockups yet....will post my results here.
I meant to ask how long did your screen have to be off before it was unresponsive?

Same thing happened on my initial one. Tried doing a bunch of things to fix it like restoring it and downloading the newest firmware from another thread and nothing worked. Exchanged it and the new one works just fine.

My wifi is set to be on during sleep.

Ok so about 8 hours so far, no sleep of death yet. Though I haven't tried leaving it idle for more than 2 hours..
I unboxed, booted, updated both updates to 3.2.1, charged to full. Then rooted. Played a bit, currently have wifi set as it was default "sleep when screen off" though I most likely will be changing that to never sleep when I'm travelling.
On a side note..I used to use whatsapp to text with my wife for free when I'm out of the country. But our one year is up and can't really justify paying twice for it for the amount we use it. Is there an alternative to whatsapp that doesn't slaughter battery life? I was going to go with kik messenger but it was causing massive drain in my testing..just running in the background. Also tried IMSY and I think its garbage.
Would love others opinions were also looking to video chat if we can since I now have a ffc. But she will be on the PC. Are skype and tango the best choices?
Wish there was an all in one app that could text/call/video call over wifi with android users as well as pc...does it exist?

Google voice allows you to text; GroveIP allows you to make calls using Google voice, Talk allows you to chat and I also believe video chat.

[Q] Stuck Data Issue?

Hey guys, got a question. Has anyone run into the issue of their data randomly getting stuck, with just the upload arrow illuminated? When I'm using the hotspot feature, this happens much more frequently.
Thoughts?

Dunno about a fix, but you're not alone. Happens to me all the time.

Fix is to toggle airplane mode as this resets the radio. Juggernaut statusbar toggles ftw.

Yeah, I switch between "GSM/WCDMA" and "WCDMA only" when this happens. It's a real pain. I downloaded a 2.1-2.2GB program while I was at 4.44GB used and T-Mobile said I used about 30 megs as far as they know...seems to happen more when I get closer to 5 gigs, I dunno, maybe they're onto me xP

Leave network settings in auto mode and try enabling and disabling airplane mode. This always fixes it for me. I have encountered this bug on multiple devices after tethering. Happens less on the t989 because tethering is native (probably).

This happens all the time.. I've always thought it was quite curious.. seems like some "uploading" going on, don't like it at all..

I've had this happen to my T-mo SGII and Sensation...just stuck in upload and any other data requests (Web, email...) are null when this is occurring.
I wonder if T-mobile is probing our phones for information when this happens?
Either way, it is annoying and toggling airplane or data seems to solve...tho I've had it go right back to doing that today after toggling...

[Q]wifi dropping

I Can't find a thread about this, so I was go ogling and that doesn't really help. I am having major problems with my wifi it keeps dropping non stop and it's really annoying. I have my phone stock but rooted and was wondering is there any way to fix this? I know it's a Samsung problem but if I were to load this up with a rom should that help? Thanks in advance

Maybe it's your router or better yet the router settings. Have you tried changing any of those settings?

Am I missing something? How is it a Samsung thing? What kind of router do you have?

After looking all night I found a thread that fixed this. You have two choices really to fix or buy your router which I'm not going to do, or you can type in on your dial pad *#0011#. Then you click your menu button, click on the wifi option, and then disable the energy saver wifi mode. That made it so my phone wouldn't drop wifi connection anymore. NOTE: each time you restart your phone you need to turn the wifi energy saver off through the command *#0011#. Hope I helped some of you because this bug is truly annoying.

That stinks. I don't have any problem and I think this is only the 2nd time I've seen anything posted like this about the S4 (the S3 did have that issue and was common). I've never turned off any energy saver and mine stays connected 100% of the time. So you're saying either that or you have to buy a new router? What kind do you have now and what settings on it did you find out that cause this issue for you?

Right now I have whatever Verizon gives fios customers. It works perfectly for all my phones, tablets, and computer. Just not on my s4 unless I do the dial pad trick. I'll post a link on the xda thread when I get home on how to fix your router. It really does make me angry that I paid 600 for the phone and it does this. Hopefully Samsung fixes this soon since they acknowledge the problem

My gf has an S4 and has the same problem. We have a Netgear WNDR3500. So it's not isolated to a D-Link. She also did the dial pad trick and it seems to work for her as well. Need to find a script to run on boot to set the power save to OFF.

Wish the aosp browser wasn't crap on 4.4. Also wish WiFi autoconnect worked in 4.3. Its really annoying that it randomly stops working until you manually open the WiFi menu. It still occurs even on cm10.2.0

what exactly do you mean wifi auto connect fail? It has been auto connecting for me? do you mean auto connect as in walk home, phone detected wifi signal and automatically turn wifi on and connect? if thats the case then i have no idea as ive never tried to do so.
Anyways.........anyone know a good cm11 kernel? currently i am using stock kernel and maaaan its missing so many functions D:

testing since yesterday, the rom is stable and whitout problems, don't had crash etc, just have a glich when u take a screenshot (in the preview) but the captured immage is fine.
I think the only thing that must be fixed is the browser, some times is choppy, double tap for zoom sometimes don't works and the video preview don't work.
I'm not sure but i have noticed a slight battery drain, more than the 4.3 stock:good:

It doesn't happen in cm10.1 or 10.0. It started happening when google changed the wifi framework in 4.3 to the always on scanning. Even with that setting disabled the scanning is still glitched.

pretty stable nightly
Using CM11 nightly since yesterday. Had no issues except the screenshot preview. Screen shots are gettive saved correctly though. Also a little drop in battery life but maybe cause I am using it more. Is good for daily use.

I have flashed the nightly and there are 2 issues so far.
1. google now does not work
2. Spotify only plays 5 seconds then it goes mute while the playback continues.

I've found another issue: except for whatsapp and SMS I don't get any instant messaging notifications. Fb messenger as well as hangouts don't show anything in the status bar.
Funnily I use hangouts for SMS and it shows SMS...
Can someone confirm that?
Apart from that the only thing that really bugs me, is the glitch when playing music and powering off the screen. I would call it Playback-bug.
I dirtyflashed though. Too lazy to wipe, don't want to lose a lot of the stuff.
If nothing helps, I will wipe...

My gnex is no longer on any carrier, strictly use on Wi-Fi now, and ever since 4.3 I experience same exact thing as you. (It also seems to randomly forget access points I've saved multiple times for no reason hahaha)
