[Q] WiFi and Bluetooth turned off on boot

I have a stock Verizon S5 that I've had for about a month now. Initially I rooted it using Towelroot, then I unsuspectingly applied the OTA update to NE9 which killed my root. I've decided to just keep the phone unrooted going forward and haven't tried to root it since the NE9 upgrade.
Since upgrading, I've noticed that every time I power up my device, or restart it, the device seems to remain in a hardened state for an indeterminate amount of time. The most obvious symptoms of this include the WiFi and Bluetooth being turned off (but NFC will stay on if it was on before). I've also noticed that if you plug it into a computer, the USB will say it is connected as a media server, and the computer will acknowledge a USB device has connected, but it won't show up in Windows.
If I manually turn on WiFi and Bluetooth, the WiFi will find a network, connect to it and get an IP Address, but then it gets stuck on "Checking the quality of your Internet connection..." This can go on for 10 minutes or more. This means that for however long the phone decides not to connect to the WiFi my phone is using up my cellular data unnecessarily.
Without warning this hardened state will go away and the WiFi and Bluetooth will turn on if they weren't already manually turned on, it will connect to a network, and the USB drives will become accessible.
I was worried this might be an issue with applying the update while rooted. I've Used Odin to flash the NE9 stock ROM on the device. The issue has persisted after the flash. I'm wondering what could possibly be causing this behavior and if it is now worth doing a factory reset to see if that fixes the issue. I'd rather not do that and find out it didn't help because then I'll have to re-setup my phone.
Anyone experienced this, know what's causing it, or if a factory reset might fix the issue? Thanks!

[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.

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 losing connectivity often

Sprint SPH-L720
Currently running Optimized CM 12.1 with OD2 modem, but the problem persists regardless of ROM or modem. I have tried NG2 modem and I have tried Stock 5.0.2 ROM as well as GPE and nightly CM 12.1.
The symptoms are these: when connected to any wifi 2.4ghz or 5ghz, secure or public, during heavy wifi activity (large downloads/streaming music, etc) my wifi connection with just stop transmitting/receiving. It will appear still connected but no data will transfer. If left in this state for long, it will disconnect and all known wifi APs will show "wifi connectivity failed". This also happens nightly when the phone is left idle over night. I wake up to no wifi connection and all known APs showing the connection failed error. I can tap any connection and it will reconnect just fine. I can also cycle wifi power and it will reconnect just fine.
I suspect this is a faulty Wifi chip considering I have tried varying everything else possible. For now I'm going to see if I can get by with a tasker profile that resets wifi power periodically when connected, but I still have the ability to RMA if that doesn't solve the problem satisfactorily. I just wanted to see if anyone else had experienced this particular issue or if anyone had any other ideas. I have found a few other threads for this phone with wifi issues but none of them had the same exact symptoms and none of the fixes described solved the problem thus far.
Thanks

910F MM: WLAN doesn't automatically connect anymore

Hi all,
I noticed a weird problem after I installed the latest Marshmallow update on my N910F. The WiFi will not connect as soon as I'm in range anymore, but it will connect immediately when I switch on the display.
I noticed the behavior because I configured a Tasker task that will wake up my PC as soon as I connect to my home WiFi. The last two days I noticed my PC was off when I came home so I switched on my phone and saw that the WiFi was not connected, I was home for 10-15 Minutes. A view seconds later after I switched on the display WiFi started to connect (and my PC also woke up because of my Tasker task).
Once the WiFi connection is established it will stay stable - I checked my router logs, so turning off the display will not disconnect the WiFi. Of course I set my WiFi to stay connected in standby.
Has anyone experienced a similar problem?

I was having issue not this kind but whenever i diconnect to my wifi and then again teconnect it again it takes time to surfing the internet about 2 minutes.when i open browser and any site it first shows connection time out then i have to wait 1-2 minutes then it loads the site.i dont know i have noticed new settings under development setting there is network setting in there there are lots of option.one option is connect to lollipop dhcp .i tried to check and uncheck that also but didnt work out.

Today it did not switch on my display when I came home but waited to see how long it would take my Note 4 to connect to my WiFi. After 25 Minutes it connected. I wonder if this is some "doze" feature.

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.
