[Q] WiFi and Bluetooth turned off on boot - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

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!

WiFi Connection Unsuccessful Message

I've noticed that my [rooted] Vibrant frequently has trouble connecting, or staying connected, to WiFi networks.
At first I thought it was specific to my Verizon Actiontec WiFi router, however I've also noticed this at my office, where we use Motorola routers, as well as a few other locations that I frequent.
It's still possible that its a site-specific problem, but, less likely as I'm seeing this in a few locations.
Symptoms:
I configure my phone to connect to X network.
It successfully connects and all it fine.
I get out of range, it no longer sees network X and disconnects.
Some time later I return to my previous location and expect that in N seconds/minutes the phone will automatically reconnect.
A considerable amount of time passes and I notice it's still not connected.
I check the wifi settings and it days connection unsuccessful.
I tap the network, click connect and it works.
I've also noticed this after connecting to a network and the phone goes to 'sleep' or into an idle state. When a wake it up, it doesn't always automatically reconnect.
Anyone else seen this?
Any suggestions?
Many thanks.
i've had that problem. i am not sure what it was because I was rooted and Ryaned. I got sick of all the stupid lil bugs and had to wipe format and unroot. Now that I am back to the original condition, theres this sense of comfort knowing if something buggy happens, it's not "my" fault.
Thanks for the reply.
I noticed this prior to rooting and 'Ryan'ing'.
The capacitive buttons don't work all that well from time to time - specifically the Home button so maybe I should just exchange it. I'll call TMO tomorrow to see what they say.

[Q] T-Mo G2 Rooted/Stock OTA 2.3.4 Wont stay connected to wifi

I tried searching and I've not found this issue addressed, but I may just be doing it wrong. But, here it goes anyways...
This house has 3 T-Mobile G2s, all with the same OTA. Only mine is rooted. However, none of them will stay connected to wifi. The wifi icon is showing up and it says that I am connected to the access point, but in status it says that mobile network status is disconnected. I can't do anything data related after it times out. If I disable and re-enable wifi it stays connected for a bit before it goes dead again. The handset doesn't go into sleep/screen doesn't turn off. Before I updated I did a Factory Data Reset, then re-entered all my information then let it update. Is there anything I can do, or try?

Being that all 3 phones cannot stay connected I'd be inclined to say look at your router... I'm assuming you've done all the obvious things like reboots, battery pulls, "forgetting" your network and then re adding it? Are other devices in the home able to maintain a wifi connection... your computer, for example? You've tried resetting your router?
If the screen isn't timing out, have you checked your Display settings? What makes you think the screen timeout is related to the wifi problem?
Well in the past on my myTouch 3g... wifi at times would get wonky after the screen timed out/it went to sleep. So was just adding that information here. Yeah, there are at least 8-9 other wifi devices here that can connect to the router just fine and send/receive data. I've tried "forgetting" the access point and then re-adding it, resetting the router, battery pull... and the same thing happens. And the router doesn't have MAC address filtering either. Can't ping google.com or 72.14.204.105 from the phone, but my pc can just fine. If I disable wifi it works as it should. Its just I only have realllly slow EDGE service in the house.

Hmm... by default wifi should turn off when the screen times out. Unless you've changed the wifi sleep policy. I had mysterious wifi trouble before on a different device (endless "obtaining ip address" loops) and the only thing that worked for me was restoring an older nandroid. Obviously, you're no longer rooted and that's not an option... but it's super unusual that 3 G2 phones are experiencing the same problem. And they're all running the Gingerbread update, so maybe that's the common denominator. I'm sorry I couldn't be more helpful. I'd definitely pay T-Mobile a visit.
I've not messed with the wifi policy, but my last phone would just drop wifi completely and I had to forget/re-enter everything to get it back. If it was the update then I would think the problem would be more widespread. Going to try fiddling with the router some more since that would most likely be where the issue lies. All else fails will just rollback to an earlier nandroid, like you had to do, and seeing if I can't get at least mine consistent. Thanks for your help and letting me bounce ideas off of.

[Q] Stock N10 with 5.0.1 will not remain connected to Wifi. Works in Safemode.

Stock Nexus 10 - Not rooted.
Following OTA upgrade to 5.0.1 LRX22C
Connection to home wifi cannot be maintained. After entering the password, approx 4 seconds later, the connection drops. Subsequent attempts to re-enter the password result in the error "failed to connect to network".
If I turn off the device wifi off and on again, I can reconnect for all of 4 seconds once again, before the connection drops once more.
I can connect to the wifi hotspot on my phone without issue.
If I start the device in safe mode, it will connect to the network, and remain connected indefinitely.
Unfortunately, this is my daughter's N10, and there are hundreds of apps installed. Methodically uninstalling them, and trying the connection will take me weeks.
Are there any suggestions to more quickly identify the app that is causing the wifi to drop?
I think one by one is the only way to be sure. I have though heard that anti-virus apps have proved particularly troublesome for some people on Lollipop. If there's anything on the tablet like that then I'd look there first.

Have you powered down/up the home router? Or forget and then add the wifi details on your tablet again? It won't take that long to uninstall a bunch of apps at the same time. You could do a binary chop, or do ten at a time. Reinstalling a bunch of apps - all of them, even - won't take too long if you do it via the google play web site.
Solved.
It was McAfee All Access. And specifically, the Web Security, Wifi Security setting.
Turned off wifi security, established the connection, saved the connection, then turned wifi security back on. No problem anymore.
Why it did it is not yet understood. We have several android devices running McAfee security. Only the one with Lolliepop suffered this issue.
Thanks for the tips guys.

[GT-i9515][CM12.1] problems with wifi, encryption and bluetooth

Hi,
I'm having some issues with sombree's CM12.1 port for the i9515.
* wifi: sometimes the phone disconnects from and won't reconnect to roaming wifi setups when changing the AP. Disabling and reenabling wifi helps. No problem with non-roaming wifi setups though.
* encryption: I tried to activate the phone encryption. Android said it would take a long time to encrypt the phone, asked for a password, rebooted and started the encryption. In a jiffy it went up to 100%, then 120%.. 140%.. etc. It took about 5 mins, then the phone restarted and asked for the password. Well, at least it tried to restart, but all applications went "stopped". The phone was unusable. When booting into recovery I found the phone's partitions encrypted. Anyways I had to do a factory reset and restore a backup to render the phone usable again.
* bluetooth: I managed to pair the phone with my Honda's hands free talk, but it won't connect automatically. I have to switch off and on the phone's bluetooth, restart the car, sacrifice a chicken and select my car in the phone's bluetooth settings and it *may* happen to connect. That's really annoying
Any ideas of what I can do to get that stuff working?
Kind regards
Brick

You cant do much about it, its the bugs for the rom you are on.
You can wait until these bugs are fixed or change your rom.
Darn. AFAIK there are exactly two roms I can use with my i9515: sombree's cm12.1 port and stock, are there any more?

WiFi problem after update

Help!!! After update to 7.0 my phone has trouble connecting to WiFi. It's not mynetwork because other devices connect and it happens at my workplace too. I've tried clearing the partition cache, restarting it and forgetting the WiFi. Even putting it into airplane mode for a few minutes. I'm not very techie so please keep keep answer easy to understand.
I think I fixed it. I went to my Google account and there was a way to restore my wifi settings.
My wife's G4 has been having the same issue... I cannot get it to reliably connect to any wifi network. Very occasionally it will connect but it only lasts for a few minutes before dropping again. Most of the time it just doesn't see any wifi networks available. I've tried resetting to factory, I've reset default networks under wifi settings, I even applied the new system update that came out yesterday, and still no luck. This is very aggravating. Anyone have any ideas?
