WLAN_WAKE wakelock + Wi-Fi not showing - Galaxy Note 4 Q&A, Help & Troubleshooting

I'm at a loss here and i hope somebody can help me out here.
I've had my Note 4 for a while now, working great, but after a week or two after flashing Simpl-rom (latest)(Android 5.0.1) it started to drain battery while the screen was off.
I tried to debug this issue and found that WLAN_WAKE is preventing the device from sleeping.
Of course i did search for solutions but none of that worked, disabled all the background scanning and stuff in advanced wifi settings.
I tried to freeze all my regularly used apps planning to unfreeze them one by one to see when the issue started to show up, odd thing is, the issue persists even if i freeze all my daily-use apps.
I also noticed no networks in range show up in my Wi-Fi list, only the ones that i saved in the past (of course most showing out of range).
Using a 3rd party Wi-Fi manager works fine, it detects all the networks in range.
Disabling Wi-Fi allows the phone to go back to sleep again. However, when enabled again after that no more sleeping occurs.
The only "solution" to this is a full reboot. This solves the wakelock/batterydrain issue temporarily but not the Wi-Fi networks not showing up.
It can take 30 minutes before the issue shows up again or it can take half a day.
I also tried to detect if any apps were using background data, none that i could detect.
Even stranger, i have the exact same issue with my Galaxy S5 running Omega-rom (latest). (Android 5.0.1)
The drain on the battery isn't huge (10-15% per night), but it's there and unnecessary (i know it can do with 2-3% per night if the bug doesn't occur), obviously something is going wrong and i wish to find out what and resolve it.
Anyone experienced similar problems or knows how i can proceed to debug this issue?
I say issue because i feel these problems are related, they could be separate problems though..

Data Constantly In Use

So for the second day straight my phone battery has dropped to half in about 4 hours screen off in my pocket... After closing every program and turning off data sync, the 3G connection is still constantly in use. I downloaded a network traffic program to check usage, and to my surprise my phone had downloaded over 60MB in just 1 hour. I restarted the phone and the problem seemed to be fixed, however it's started back up again, even after restarts and switch from airplane mode and back.
I'm already using SwitchPro, I have all sync options turned off already. The problem didn't come up until a few days ago.
I haven't installed any new programs or widgets in the last couple of daysIs anyone else having a similar issue? Have you been able to solve it?
I had the same issue then I flashed Fresh. Now it is working proper. I would suggest flashing a dif ROM or factory reset.
Load aLogcat or Quicksysteminfo , from market and look at your logcat file. The cause will be obvious from there. If the phone is "idle" and the logcat is recording what's doing the data moving, you can then kill it.
Is it me or is the hands free Bluetooth constantly running even when unchecked.Maybe im looking at the log cat wrong but it appears that way
It looks like location services was using all that data. I think anyway, I'm not sure If read the logcat right, but a lot of that information dealt with location stuff. I went to settings, privacy, and disable google services from using my location and the constant 3g seems to have stopped.
Why would it just go ape **** like that after having the phone for 3 weeks?
I just noticed the same problem, turns out it was the people app that was causing it. I killed it and data traffic stopped. You can launch it from the menu and it loads back up and is fine. Just seems to be when it starts by itself when you first boot up the phone.

[Q] Seeing a very major wake-lock from Phone > IPPolicy. 12+ hours!

Google search shows nothing for IPPolicy. I have no idea what is responsible for this wake-lock but it's wreaking havoc on my phone!
I've tried the usual factory restore to no avail. Some days it will be a minimal wakelock, others it will be 4-12 hours plus. What is the deal here? Wifi calling is enabled whenever I'm on wifi, and I'm connected to wifi a lot lately due to being home. Location services are set to device sensors only.
http://tinypic.com/?ref=2yu0zgk
Here's another shot of what is going on, it's referencing the phone.apk as using the service. I just rebooted my phone not too long ago so this doesnt show the wakelock ippolicy at full force but you get the idea. I have disabled wifi calling to troubleshoot and it does seem to stop, that was yesterday, but then today when I re-enabled wifi calling and checked, the wakelock was there again, however when I disabled wifi and wifi calling, and refreshed the WLD display, IPPOLICY was still growing in wakelock. So I really cant tell you what the deal is. And I have no idea how to track it down, but it's killing my battery. As you can see from the first image at the top, that 12 hour wakelock was while sleeping!! While on wifi all night.
Even with 20e update, WiFi calling is still causing this wake lock, anyone else see this?

Wifi always on in battery report after Lollopop update

Ever since I upgraded to 5.0 using the stock images and the "Return to stock + unroot" option in Wug''s NRT I've be experiencing this bug.
When I'm connected to a WiFi and walk out of its range and then disable Wifi from toggle or settings the battery stats will display Wifi as ON all the time. If I reboot, then it will show as OFF again.
If I turn off wifi while still connected (in range) battery report will show wifi as off.
Same thing happens also in SAFE MODE, so I don't believe its a third party app causing the Wifi radio to hang.
I've read several other users experiencing this problem, so I decided to create this thread and try to find a solution.
android 5 known bug
So, no workaround?

Extremely frustrating WiFi issues

So, I have been having some extremely frustrating issues with the WiFi on my 6P. I got my phone in January and I have been super happy with it except for this one issue. Since I got it, I was using the stock OS up until the April security patches came out. Before the patches, I had some issues, but the phone was still mostly usable. Especially after that update, however, I have been faced with two very irritating WiFi issues.
When my phone goes to sleep, the WiFi connection inevitably drops out. Sometimes, the WiFi will still be active but not associated, but it will frequently have also switched itself off completely.
I can only stay connected to a network for about 30 seconds tops. The connection will just stall out and then reconnect after several seconds.
In an effort to get better performance, I decided to switch from the stock OS to PureNexus (which I used and loved on my old Nexus 5) and I also flashed the ElementalX kernel. For the first few days, the WiFi performance was rock solid, but slowly it got worse than it was on stock to the point of being unusable now. Now, here's what I have already tried/checked:
The "Keep WiFi awake during sleep" option in the Settings app is DEFINITELY set to Always.
This issue is not specific to any one network. It had occurred on every network that I've used and on 2.4G and 5G networks (although it seems to be worse on 5Ghz)
I tried turning the band selection off Automatic and choosing both 2.4 and 5 only options, both just seemed to make it worse.
I've removed all apps that I installed and checked logcat for any app info that might be related to the issue. All I see is just normal stuff and then BAM! The wifi driver states that it disassociated from the AP.
I tried installing WakeLock to hold WIFI_MODE_FULL at all times. This hasn't made much of a difference with it disassociating while the screen is off.
Has anyone else experienced issues like this? I am to the point now where I might have to send in my phone under the warranty because I don't know if it's just detective hardware or what at this point. The fact that it worked well after a clean install would seem to suggest that it isn't, but the fact that it persisted across two different ROMs suggests that maybe it is.
Either way, I am at a loss and I've exhausted all the diagnostic skill that I have trying to fix this because it's so damn frustrating when you're in the middle of doing something and you can't stay connected for 30 seconds. Any help or ideas would be appreciated immensely!
My issue is the wifi connects but no internet message
Sent from my Nexus 6P using XDA-Developers mobile app
Is this with different Access Points or just at a particular wifi spot? I would factory reset the device, reboot your router, make sure you don't have any odd settings on your router like modified channel bandwidth, etc. If the 6p doesn't stay locked on, it's a hardware issue and I would do a warranty claim. My 6p wifi has been money since January with every ROM.

WIFI turns on and off constantly

when turning my wifi off it seems it goes into some weird loop of turning on and off constantly by itself, it doesn't seem to be trying to connect just flipping the wifi switch on and off none stop.
noticed it because i had a huge battery daring overnight and while trying to fix it i saw the switch going off and on all the time.
when turning it back on it seems to connect normally .
did a network setting rest but it did nothing ...
I'm guessing a factory rest will fix the problem but I'm hoping to avoid such a overkill solution :crying:
does anyone else had this problem and can help me fix it?
thanx!

original samsung rom.
just happened (i have the device for a a while everything was fine) its the android system that drains the battery in the battery status.
when i leave the wifi on it stops and works fine ...
Have you turned off ''Keep Wifi During Sleep''? I know this can drain battery.
It's not so easy to troubleshoot on an orginal none rooted phone.
You can try clearing dalvik and cache.
Turn it off and then on holding power and vol down button, then clear cach/dalvik and restart.
Try uninstall update beaming service for samsung then restart
If still persistent try uninstall update microsoft onedrive and skype then restart, just in case
I found it after factory reset (forgot internal data backup :crying and update all apps, this problem occuring after the last 3 updates (beaming, onedrive, & skype) which more suspect beaming service update make that problem
Your not alone
You're not the only one who suffer from this exact problem, on Friday or Saturday the same problem started occurring with my phone too, WiFi turns on and off in a loop and huge battery drain!
I saw an increase of 6% of battery drain per hour, so I ended up on 9% total drain every hour. :crying:
I have original Samsung Rom and phone worked prefect until now, no settings or apps installed before this happened either.
What rom version are you guys on?
I'm having the same issue. However, I'm on PhoenixX Rom. Major battery killer and has only just started happening within the past few days.
Since my phone has been unplugged, 3 hours ago, looking at BetterBatteryStats, It is showing com.google.android.gms as having quite a LOT of wakeups. 40 per hour (everything else is about 2). Don't know if this is normal as I don't remember it before the Wifi issue.
Looking into what the wake ups are caused from, Location and heartbeat were the major culprits. So i have turned of WIFI scanning when not on and also the body sensors for Google Play. We shall see.

Easy fix. Just disable Wi-Fi scanning.

its not a fix at all . it dosnt scan for wifi , just turning it on and off non stop.
like pressing the light switch agin and agin
I had this after installing "GoodLock" software from Samsung! Uninstalled and everything is ok
same here, just noticed I wasnt on Wifi and the switch is just flicking on and off by itself. Standard S7 with all the updates installed
Been struggling with the same for some days (4 - 5) I haven't been able to get exactly whats triggering this. I'm on stock rom with root. I've reinstalled firmware clean again and re downloaded my apps but it is still happening randomly. Some times after a few attempts to switch wifi on (even when it is toggling by itself) it manages to keep on. Sometimes restarting makes it work again. One thing I'm almost certain its that this usually happens after I turn wifi OFF and then try to turn it back on.
It's been crazy and the phone starts to overheat after a while off this on-off loop.
Any ideas?
its very wierd it started to all of us in the past few days-weeks . seems like samsung has a bug they need to hurry up and fix.
AT&T just pushed out the October Security update for the S7 family, I'm guessing something that came along with it is creating the problem.
mine did a software update last week and I've been away in airplane mode so it could have started then. I've just disabled scanning and that seems to have got round the issue and I'm now connected to WifI
I'm not sure whether it is a Samsung Issue or a Third party one... It is true that something recently affected all of us, but as far as I know, it could be a third party app that wasn't well developed for our phone.
I've noticed the same problem on my phone and it's also only started up in the last few days. On stock Sammy rom, unrooted. Will be monitoring this thread to see if the experts here can narrow down the culprit.
I had the same issue and I was able to stop the toggle by turning off the wifi scanning in Location - Improve Accuracy - WiFi scanning. It's a fix for now. I think it may be an app that may have been updates that is persistently looking for location updates.
