[Q] Battery drains when connected to certain WiFi network - Galaxy Note 3 Q&A, Help & Troubleshooting

I'm having a problem that has persisted across my last 2 devices, my previous Nexus 4 and my current Note 3. When connected to wifi at work, my phone will not sleep and is manifested by "Android OS" awake time show up in the battery information. Today I did a test, 1 hour with wifi on and 1 hour with wifi off. For the hour wifi was on, Android OS kept the device awake for 47 minutes. For the hour wifi was off, Android OS kept the device awake for only 2 minutes.
From my research there seem to be two possibilities:
1) A wireless router problem--outdated, incorrect settings, etc.
2) High volume of data that is broadcast to all devices across the network--something on the network is repeatedly pushing data out to my phone and waking it up.
I've ruled out an issue with the phone or an issue with a particular app, as this problem only manifests itself on this particular wifi network.
Unfortunately, since it's the work wifi network, I don't have access to router settings, hardware, etc.
Does anybody have any ideas how to remedy this or am I just going to have to avoid connecting to wifi at work?

[Q] Wifi continuously scanning while phone has good wifi connection.

This started Feb 3rd or 4th. The phone will connect to the wifi network, with a good signal. It will then re-scan every 5 seconds or so. This is causing all sorts of data transfer issues from downloads freezing to apps losing connectivity while running.
I am running on Verizon.
Specs below: (Sorry can't direct link yet...need 10 posts)

I am now running Android 5.0 but had NOT updated to 5.0 when this problem started.
I scoured google a bit and found an ATT forum that is essentially reporting what I am.
forums.att.com/t5/Samsung-Discussion-Support/Samsung-Galaxy-S5-Wi-Fi-Connectivity-Problems-After-4-4-4-Update/td-p/4190704
All other devices on the network are operating without issue - phones and computers - as was mine until now.
I have power cycled everything.
I have checked the routers settings.
The phone has been power cycled several times.
The phone has had every wifi setting that would be causing this scanning, that I know, disabled.
The following are off in Wifi > Advanced:
Wifi notifications
Passpoint
Always allow scanning
Smart network switch
I then, after the above, updated to Android 5.0. The issue still persists. Help me please.
My device does this, too. Cant say I have ever really noticed, I dont know if it has always done this or not.
I am not experiencing any issues like you describe.
Now that I think about it, I think it will always scan at a set interval when you enter the Wifi settings. It assumes you are looking for a network to connect to. I doubt its scanning when you are not in that setting.
I had this problem the other day. I went to wifi settings and had it forget the network and then rebooted and reconnected to my wifi network and it seems to have resolved the issue. others have just switched airplane mode on and off and this fixed it. good luck

Wifi Issue with Nexus 6P

Hi everyone
Just got my 6P two days ago. Love this phone but I'm having some issues with the wifi. so here is the situation:
When the phone goes into sleep mode and when I wake it up , the wifi does not automatically reconnect to my routers. on the wifi list, it has "Wifi Connection Failure" listed for the saved connections.. Here's what I already checked:
1) I made sure in the settings that the wifi is always on even when sleep
2) I have three different brands of routers in the house and all are the same error when the phone is woken from sleep (linksys, Dlink, tp-link)
3) factory reset the phone, no change
all my wireless is set to WPA2.
Has anyone experienced this? Wondering if there is a setting or do I need to RMA this phone. thanks

WiFi cuts in and out when bluetooth is on, works fine when bluetooth is off

On my 6P, the flow of data on WiFi stops every few minutes, remains out for 10-30 seconds, then comes back. Usually, it will fail over to LTE data automatically. Then after 30 seconds or so, reconnects to WiFi. *THIS 100% ONLY HAPPENS WHEN BLUETOOTH IS TURNED ON. * If I turn Bluetooth off, WiFi remains on rock solid.
I don't know if it's related or not, but the only time I can get it to use WiFi for calls/sms is if I put it in airplane mode so it had no choice to use WiFi. It will never switch to or utilize WiFi calling automatically. The 3G signal in my house is nearly non existent, so it should be using WiFi in nearly all cases.
I use Pure Nexus. Updating to the latest version 2 weeks ago made no difference.
I have already been down all the roads with routers, WiFi channels, DHCP, and any other fix that could possibly be unrelated to the 6P. It's none of them. Again, this only happens with bluetooth turned on, and does not happen with bluetooth turned off.
Any suggestions? 

Wifi keeps switching on an off

Dear all,
I'm experiencing a somewhat weird issue with my Xiaomi Mi A1 (Oreo) which started a couple of months ago.
My WiFi keeps switching on an off.
* When I turn off WiFi, 4G comes up. After a few seconds (I can leave the phone unlocked at the desk, it almost happens instantaneously) Wifi turns on by itself and connects (just as if I switched it on manually).
* When I activate the mobile Hotspot, it switches off after a few seconds, disconnecting all devices connected, only to switch on the regular Wifi after a few seconds and trying to connect to the next network.
* In random cases, Wifi just switches off despite being connected to a working network and while I'm using it.
This is somewhat annoying, and I didn't find any solutions online. Any ideas? Any more information you need (sorry, I'm new here)?
EDIT: This is not the "Turn on Wifi automatically" setting, and it is also not related to location services.
Flash stock rom, sounds like a software bug. Otherwise, return it while you still can.
Thanks.

US996 - Unconnected BT causing packet loss in wifi

I have had my US996 v20 for a couple months now and noticed that websites and apps were having trouble loading pages. I was able to verify via terminal editor and ping that I am losing somewhere between 6 - 20% packets, this happens on multiple different wifi networks.
Today I decided to try disabling the BT and see if that had any effect. To my surprise I stopped dropping any packets. Is this a known issue with this phone? My BT wasn't connected to any device so I don't think the BT radio should be communicating with anything.
I narrowed it down to the bluetooth OBD reader in my car. I'm still not sure why it was causing wifi issues but since it was always powered even when the car was off, and most of my day I'm within range of my car, it was causing the wifi issues almost all the time. When I unplugged it, suddenly I stopped seeing high packet loss.
