I have a AT&T S III on Android 4.3 Stock.
I keep getting "your internet connection is unstable" on my WiFi & anywhere I can get a WiFi signal. The signal strength is full and the issue still persists. I have tried wiping the cache partition, clearing the app cache on WiFi Direct and WiFi Direct share. Also unchecked "Auto Network Switch" in WiFi settings.
Any help would be appreciated.
BTW. I am using a Netgear R7000 Wireless router at home.
I don't know what a solution to this problem is but when I first got my S3 back in August it did that for about a month then just stopped and I never saw it again. In March I had a warranty exchange because my screen went black and the new one started doing it, too. Again, it did it for about a month, then it just stopped. have you recently replaced it or done a factory reset? Just an idea. Sorry I couldn't be of more help for a direct solution.

I had that too, and I think the easy fix is when the notification pop's up saying "go to settings.....blah blah......" Hit the don't ask again radio button, then OK. When I did that it never showed up again. Hope this helps.

Yes you can downgrade with Samsung Kies. I don't have the exact directions but Google it you will find directions.
It depends on your bootloader. If you are on mjb then no you cannot downgrade and risk bricking your device if you try. If you are on mj2 then downgrade away.

Two days ago I turned off my GNex and as I turned it on and tried to turn on the WiFi, it get stuck with the writing "turning WiFi on" and the WiFi "button" blocked (I can't turn it neither off nor on).
I tried to reboot several times but the phone is stuck with this problem since the moment I turn it on.
I never modded anything with my Gnex, never changed ROM or kernel, so I found this problem quite strange.
Does anyone knows how to solve this issue?
Thanks in advance

so i assume you are completely stock. hard reset should fix the issue. i have seen this before on other phones and the hard reset seems to fix the issue.

Check the system logs i.e. 'logcat', 'kmsg' to check if something's wrong with the hardware.

Your next step, if factory reset doesn't solve it, is to reflash factory images. It will wipe your device's entire memory. Step-by-step instructions here.
I'll try to flash a factory image asap, thanks
Wifi switch Grayed out
My Sprint Galaxy Nexus is presently on 4.2.1 and has been facing wifi issues. The Wifi button/switch/toggle under the settings options has "Grayed OUT" and wouldn't allow me "ON it".
This happened after I downloaded an app from google play. However after which i removed the same by unistalling it and have been facing this wifi issue since then.
I did a Factory Reset but WIFI remains "Grayed OUT". Can some one guide me to solve this issue.
Thx in Advance

Just read the thread (and linked threads). The troubleshooting steps are the same for you. No need to hijack the thread (you didn't even mention which app that was, for example, you only need to press thanks and follow our lead).
P.S: I honestly don't care if anyone presses thanks or not.
I just brought it to the assistance and they changed the wifi module

That's good, glad to hear it. Have you grabbed the logs from kernel/system, back when it was not working?
If you did get them, now we have a "template" of what the kernel and system report when it finds this kind of failure.

More details needed, is it rooted? if so what recovery and rom are you using?
Having the same issue,
I noticed today at lunch the wifi switch was turning on then off again and again.
I tried a factory reset, and not wifi or bluetooth does not turn on.
I am running stock 4.4, no custom recovery, but I am rooted.
Any Ideas?
I had the exact same issue with my P600, I did every step possible to correct it. Factory rest, rooting and flashing different roms. I finally sent it in, Knox was 0x1, apparently Samsung gave me a one-time accommodation and rest back to stock with 0x0. The report says replacment parts and labor. I'm guessing you might need the same.

Got a notice of an OTA last night. Figured it was for Lollipop so told it to proceed. Once the tablet rebooted the WiFi radio was disabled. Looked in settings which showed that WiFi was on, but no radio. Went online an saw that Samsung hasn't sent out the Lollipop update for the 10.1.
Question 1 - how do I restore my tablet since I can't get WiFi turned on?
Question 2 - where did this weird OTA come from?
Thanks for any help you can give.

Others having same issue
Thought I'd post this as info. Checked over at Android Central and several people appear to be having the same issue. Looks like bad firmware from Samsung. Bad build number is: KOT49H.T520UEUAOD1. Wiping and factory refresh may help temporarily, but eventually the wifi radio will be disabled. I'm going to wait for Samsung to get their act together and flash a fresh build when it's released.
Thanks for the help.

Wifi Issue as well
I had the same update come across last night and now I can't connect to wi-fi to save my life. Really pissed off. Done 2 factory resets already, reset my modem at home, turns out it happens everywhere and not just at home. Wifi says it's on but doesn't pick up any networks in my area and won't connect to the 1 that is already known on my tab. PLEASE HELP
Got the update last week. Wifi is fine but now daily I get a random reboot. Never had any problems before. Thanks Sammy!

You can download an earlier firmware from sammobile.com. If you are in the US, use the firmware for cellular South and make sure it's a 4.4.2 that you are downloading. After you download it, you can flash it with Odin. There are several threads here on xda that describe this process. If you still need further help, post again.
TabPro 10.1 SM-T520, v4.4.2 Build KOT49H.T520UEUAOD1 No wifi after update
Boy am I glad to find you guys with the same problem as I have. Couple of days ago I saw an update message and decited to go for it. Well, as all of you know, wifi stops working. Factory resets gets it working again but once everything is restored it stops working again! This is quite frustrating and I hope Samsung is working on a fix right now. I haven't been on XDA for a while and only rooted phones before. So how is the rooting/mod scene for tablets. Any good Custom Roms out there we can use until/when this is resolved? I'm good with directions and done some custom roms on my phones before. Let me know what's the good ROMS out there are...the bloatfree version is a welcome even without KNOX, I don't really use it.

Thanks for your feedback.
I had to use the firmware from November 2014 to get it to work and restore my wi-fi.
Again thanks
KOT49H.T520UEUAOD1 is the problem
Well I figure this particular firmware has a problem. Because even after factory reset, wifi works once and goes back to not working. So the best solution is to get an earlier version. I went back to Sep 15, 2014 version and it works well. Took forever to download from sammobile though. So if you need to flash to a previous version that works. I have post a link to the firmware I have on my OneDrive that got it working again, hopefully it will be faster for you to get your tablet working again. Here is a link. This is for the US Tab Pro 10.1 SM-T520.

thank you for those who warned about the wifi problems this OTA introduced. I'm just going to keep ignoring the tablets request to update. I thought i got a great deal on this tablet when i got a refurbished one for under $300 several months ago... but samsungs lack of support for this tablet is astonishing.

My LG G3 wifi & bluetooth stucked at turning on. Tried factory reset, flashed the ROM & use FXR wifi fix and rescue but still not working. Have not tried changing to another Kernel yet. Could it be hardware problem?
I don't think so... Maybe an app is in conflict with wifi & bt.

Similar issue on my end - About a month ago, I opened a support ticket with LG. They returned as "repaired" and my phone worked for about three days before the issue returned.
Using Titanium Backup, I restored the bluetooth system software and it worked for about a day. Considering flashing my phone back to stock and starting over.
If anyone has experience on finding a permanent fix to this issue, I'd be all ears.
Try booting into safe mode and see
I'd be very interested in a fix for this too.
I've a completely stock unrooted D855 that last week seemed to over heat and shut itself down. On restarting it's eaten it's way through the battery in very short order, gotten hot and shut down again. Rince and repeat a couple of times. I've then factory reset and its continued to do the same thing.
Further investigation has shown the WiFi and Bluetooth "turning on" constantly without ever actually turning on. And I've then discovered that the MAC address (and Bluetooth equivalent) are missing.
Would appreciate any help possible
Seems like i'm not alone. Yup my phone auto restarted few days ago after turning on wifi & it keep rebooting if the wifi is turned on. Only stable after i flash the ROM but the WiFi & Bluetooth issue persists. Safe mode does not help.
Same issue started 2 weeks ago. Factory reset didn't fix and battery life being killed by constant searching for BT and wifi. Unlocked G3. Waiting for Marshmallow in the hope it fixes it.
You could also have broken firmware when i got my g3 wifi turned on and off and always dropped connections i ended up reflashing stock with flash tool and tot method and it fixxed i had a bad firmware download straight from lg
hmm so no one has a way to fix this issue?

Same problem here, wifi and bluetooth mac address unknown, return to stock with kdz files, 10a, 10f, 20, 21a, nothing work, .tot method also not work.
On 4.4.4 = boot loop, and for android 5 battery drain and wifi bluetooth issues.
Waiting for marshmallow
i found a post by someone else in another forum that fixed this problem. I followed some of his steps to reboot into safe mode to turn off the bluetooth & wifi but it didn't work so i turn on Airplane mode while i'm on safe mode & reboot again in safe mode & it works.

Any fixes with Marshmallow ?
Would be good to know a fix as recently happened to me. Can now only use data for Internet and am getting through a battery in 3 and a half hours as the phone is constantly trying to connect the WiFi and BT. Tried Factory reset. Used LG Mobile Support to update software. Now finally have the lovely Marshmallow but the issue remains. Please help!
Has anyone found a solution to this problem?
Anyone found anything on it?
Same problem here. Wifi and bluetooth randomly stopped working. It works randomly sometimes..
Wifi mac address shows as 00:02:00:00:00:00
New Battery
Hey everyone, I had the same problem. After installing an OTA update, my D850 crashed. When it started up again, I had no WiFi/BT. I tried several factory resets, flashing multiple custom roms, tried unrooting and returning to stock. Was convinced it was a hardware problem. As a hail mary, I ordered a new battery off Amazon. I put the replacement battery in my phone, and WiFi and Bluetooth are now fully functional. Is it possible that everyone with this problem just has a bad battery? It's definitely worth a shot.
probably a hardware issue...
Hey guys,
if brysclar's hint about the battery (see right above) doens't help you, you might want to check out a detailed summary I've written about this issue here: http://forum.xda-developers.com/general/help/qa-wifi-stuck-mac-020000000000-g2-g3-g4-t3452133

I just bought a used phone on eBay for a friend of mine, and he's having the same issues. Every time he tries to connect, the phone detects WiFi but doesn't connect. I had him reset his modem and router, and still nothing. He did factory settings on his phone as well, and still nothing. I had him find free WiFi at a restaurant and try that route, and he's still having issues. Will flashing new updates fix this issue, or is there something else needed in order to fix this solution?
I guess I can always have him send me his phone since he's not tech savvy! Any help would be appreciated.
Thanks
Have you tried the N Beta? https://www.google.com/android/beta
Shouldn't make a difference, but nothing really to lose by trying it. Other than there's a data wipe if you go back to stock. When I turned it off because some apps didn't work, it installed an OTA version in one shot with the latest version up to that point. With the data wipe. No security updates needed on top. That shouldn't make a difference either, but maybe it will.
