wi-fi wont turn on - G3 Q&A, Help & Troubleshooting

Hi gang, got a bit of a strange one here. had my G3 for about 15 months so far, and save for having to send it back after a few months for something i cant remember, its been a great phone until tonight when for some reason, it has decided to not connect to wifi or bluetooth. I have tried rebooting numerous times, and still the same. I have ran a factory data reset and still the same. When i factory reset the device, i tried to connect to the wifi however the phone simply rebooted and carried on rebooting until i took the battery out. If i get into the OS on the phone, and try to turn wifi or bluetooth on they simply say turning on, but never complete the turn on and seem to get stuck. My phone is an unrooted phone as i need it for banking apps that wont work due to the root.
I have searched on the net and have noticed numerous pages about this yet nobody appears to have a solution for it. i am going to give Three a ring tomorrow and organise the phone to be returned, but im just curious why this has happened? any ideas?

Same here, waiting for marshmallow official update, hope will work

[Q] Weird Issue... Somethings Very Wrong

Hi everybody... I've been using my HTC One X happily for going on 3 months now, and just out of the blue I had the weirdest thing happen. I was just cruising the internet when I lost my WIFI connection, so I go into settings to see what happened and it just says not in range(it was defiantly in range), so then I turned WIFI off, and back on and nothing. So I did a restart. It got worse. The WIFI kept saying connecting, authorizing, searching, connecting, authorizing, searching, continuously never actually connecting. So I tried restarting again. Now, the WIFI works right, but everything else is completely screwed up. I was running APEX launcher, and widget locker, and APEX launcher keeps closing randomly, so i thought well something got messed up there when i restarted so i took it off and re-installed. Nope. Still does it, so then i just took it off and its still having issues. Every time I exit an app or hit home, I get a loading thing and it takes forever to go to the home screen. I tried doing a factory reset and it won't go to the boot menu. It just starts up and then says its recovered from an error and asks if i'd like to send an error report. What the heck is going on with my phone? It's not even hardly usable the way its acting and I can't even reset the stupid thing.
a little more info about your configuration may be helpful. Is your one x stock with a locked bootloader or are you running a custom rom?
Sounds like corrupt data somewhere.
If a factory reset doesn't solve it, try flashing the RUU.
turn your router off and back on, mine did this with a Sky router at my friends house. Worked fine after.

Last ditch effort to fix wifi SGH=M919

Hello,
I have spent many hours attempting to solve the ongoing problem of the wifi button not responding but remaining gray when touched. Here is a quick chronology of symptoms and attempted fixes. I love everything else about the phone, especially the size, but am close to throwing my hands into the air. If anyone has any suggestions as to a Rom that may finally fix this, please let me know!
Wifi worked fine on phone for about 6 months, then became unreliable, not connecting after being out of range and coming back into range of wifi stations. I was usually able to force it to come on by a reset, pulling battery, turning off mobile data and calling *#0011# and turning wifi power saver off and on several times.
After this would no longer work, I rooted phone with CF-Auto-Root-jfltetmo-jfltetmo-sghm919.tar.md5 , was able to use wifi for a day or two, then nothing would force it on.
Tried multiple custom roms, including CM11 kitkat and CM12 Lollipop, same results, I would originally get wifi to fire up and connect, but after a day or two max, nothing.
Have flashed stock kernel for modem, nothing.
Took back of phone off, unplugged and plugged in blue antenna wire, nothing.
Recently flashed M919UVUFNH7_STOCK_ROOTED_DEODEX_KNOXLESS along with NH7_modem.tar.md5, wifi worked a little while, and as usual, wont respond to any resets, battery pulls, etc.
Thanks for any help you may be able to afford.
ive been having the same issue or a month or so now... cant seem to find a sulution anywhere. I too tried multiple roms, even the new 6.0 . I cant imigine its the wifi antennae because it works fine when it wants to... gettin frustrated with it.

I agree, flashing stock firmware is one of the first things that should be done in this case

I have a suggestion. Use the following link to get latest T Mobile firmware for the phone.
http://forum.xda-developers.com/showthread.php?t=
Sometimes it takes flashing the firmware twice for the full install of the radio to take properly.
To begin, remove the back of the phone, because your going to remove the battery after the first flash.
Boot into download mode by holding the volume down and power.
Assuming you know how to use Odin, before starting the first flash, unchecked the auto reboot option.
After Odin has reached the point of RESET, unplug the cable, remove the battery... Replace the battery, reboot into Download mode and
repeat the process, leaving auto reboot checked this time.
You are now completely stock. Your data will be basically left untouched.
Good luck.

Have you tried cleaning the hardware contacts on the antenna? I remember this same scenario on my old HTC Desire... the antenna contacts were dirty IIRC and they needed cleaning.
Wow, so I am not the only one still facing this issue! I flashed this rom http://forum.xda-developers.com/showthread.php?t=2539361 a few times and I eventually noticed the wifi issue as well.
Baseband: M919UVUF0H3
Kernel version: 3.4.0-2437203 [email protected] #1
Build number: KTU84P.M919UVUF0H3
Here's what I attempted:
1. Did a full wipe on the phone and installed full firmware 4.4.4 http://forum.xda-developers.com/gal...mware-firmware-kernel-modem-recovery-t3193835
2. Flashed stock kernel from the same link above
3. Installed SuperSU, flashed TWRP
4. Installed and ran TriangleAway to clear KNOX counter
Same issue as OP--at first wifi would work but the connection would not stick and I was unable to activate the wifi button anymore. I tried uninstalling KNOX but I get an error "Failed to create KNOX mode." When I reboot into TWRP, I get the message "E: failed to mount /efs (invalid argument)."
I discovered that my EFS folder is empty. I don't have a backup. Could this be related to the wifi issue? Am I screwed?
Finally got the wifi working. Took the white shell that covers the board off and cleaned the contact on the shell with a q-tip and isopropyl, but it looked kinda scuzzy so I scratched it a bit to expose bare metal again. Then I went to the board side and pulled up on the tiny piece of metal that springs to make contact, enough to bend it to a steeper angle for better contact. Wifi and BT working steady for over an hour now. Thought id share.

Heres a link with pics of the locations of the antennas
Edit:
though the wifi worked briefly after this, it stopped working shortly afterwards... back to square one...

SM-N7505 Wi-Fi not turning on

Hi everyone,
I'm having serious problems with my Wi-Fi on my Samsung Galaxy Note 3 Neo (SM-N7505). Whenever I click the button to activate the Wi-Fi, the icon goes from grey to a dull green (darker than the bright green which signals that a function is turned on), as it does when it's trying to turn itself on. Problem is, instead of turning on, it just stays in that state for a few minutes before reverting to grey. This has gone on for a while, and I've already tried several possible solutions which I found after online searches. I don't think it's a hardware issue (see point 1 for the reason), and I really hope it isn't, because my warranty has been voided due to rooting, so I can't have my phone replaced or repaired unless I pay for it (which I can't at the moment). So, I'm basically ignoring the possibility of hardware failure and trying every possible software solution, hoping one of them will work, otherwise I'm just stuck with no Wi-Fi. These are the fixes I've tried:
1) Take out the battery while the phone is on, wait a few seconds, then put it back in and boot the phone up. This used to work when the problem first presented itself a few months ago (which is why I don't think it's a hardware issue), and I've been since using this method to fix it whenever it happened again. But a few days ago, this method stopped working for whatever reason, so I was back to square one.
2) I tried renaming the data/misc/wifi/wpa_supplicant.conf file, which seems to have worked for some people, but not for me.
3) I tried updating the version from Kitkat to the recent Lollipop, hoping that would fix it, but nope.
4) I tried deleting practically every single app one by one, hoping that one of them was interfering with the Wi-Fi somehow, but nope.
5) As a last resort, I tried a factory reset, but not even that worked.
This is basically the long and short of what I've tried to fix this... I might've skipped a few of the simpler fixes I tried (for example, I just remember I tried disabling "Smart Network Switch", which seemed to do it for some people), but the big stuff is all there.
I'd really like to get my Wi-Fi back, so if anyone could help me fix this thing I'd be really grateful!
Thanks in advance to anyone who will bother to reply.
same problem dude
Same problem...wifi and bluetooth not working...pls help us
Same Problem for me, Initally it works fine even after updating Official Lollipop update (OTA), but after few months now wifi & bluetooth are not working for me. And finally faced battery drain issue for past few days. Battery goes down upto 20% per hour even in idle condition. Then i rooted & installed Note Rom & even after i face the same problem. Is there any way to fix?

anyone have a fix for wifi ?

This happens at least 4 times a day, it's annoying, I have to switch to airplane mode and back again to get it to reconnect.
I also get this sometimes . When I look at the wifi access point on the phone, it says that its down to poor internet quality .It usually corrects itself in approx 10 minutes with no action taken on my part.
Do you have WiFi set to turn off when the phone is asleep? If so, try setting it so WiFi stays on during sleep and see if that helps.
I got the same problem since I rooted
Been trying to figure out if its a VENDOR Firmware problem or what. I do know that every developer says its a bug with the s9 when rooting. I've personally watch the live log on TWRP when flashing and seen where it mounts the VENDOR Firmware and then unmounted at the end. So it could possibly be a problem between TWRP and the s9 ROMs idk know exactly yet but I'm looking for a solution also. Keep your head and keep searching also then reply back here when you find something. I'll do the same. Good luck.
Its still happening sometimes its fine a for a couple of days then it starts acting up, my girlfriends S9 does the same so maybe it's something to do with Virgin Routers.

Question Lock Screen rejects correct password after Nov update

Hello!
Around Nov. 11th, I followed on-screen prompts for firmware update (I believe the fall One UI 5.0) on my Galaxy S22. Put in the password I've used since I activated the phone in July to "complete the update" after system restart, but device won't take it and I have only a few "attempts" remaining.
Phone is Verizon, no luck with Samsung Find My Mobile; Google's Android Device Manager won't even _ring_ the phone (it showed the correct GPS location at first, but not after I let the phone die and charged it up again ... tried resetting password from here, but even several soft resets later, it now reads device cannot be reached and shows a generic map with no pin).
I've heard of people soft-resetting until it works, but I don't want to waste more attempts with the only password I've ever used (definitely used the eyeball icon to make make sure I'm typing it in right!). No way to roll back the update or reinstall it? So much data since my last backup :-/
Any ideas for last attempts into the phone before factory reset? Willing to keep trying.
-J
P.S. Was advised to move this post, hopefully I'm in the right channel now. I have pics / video to suppplement post if needed.
P.P.S. Noticing that Airplane mode looks to be enabled, but I seem able to hit WiFi icon and "connect" to home network over it.
This started happening to me today too, I have a galaxy a51 though. I recently updated as well a few days ago.
My pattern unlock worked fine earlier in the day. I put it on the charger and walked away for a while, when I came back the pattern that I've used for a long time no longer works. I've tried so many times it keeps locking me out in increasing increments of times... now it's counting down from an hour.
Soft resets did nothing, I tried many times. I don't have find my phone enabled or a samsung account linked, my google account is linked but unfortunately google forced me to set up 2FA a while ago so now I need my phone to get into that too!
The only other thing I've seen mentioned as a fix is to let the phone die completely then recharge it and see if it will accept the pattern. Mine is at 60% right now so it's going to take a while. I also don't want to factory reset as none of my data is backed up, unfortunately.
I feel like the update has to be related to this problem too. I've had several problems since doing that update and never had any of these issues prior. Did you ever figure anything out with yours?
