Device forgets all saved WiFi passwords when toggling it off and on again - OnePlus 3 Questions & Answers

Hello guys!
I have weird problem!
I got broken OP3 A3003 (64gb model) and repaired it. It works perfectly but there is just one annoying fault that i cant seem to find answer to. The WiFi will not reconnect to saved hotspots after i toggle it off and back on again. Everytime i must give the password again and again. after i connect it works perfectly an no hiccups at all. just the reconnecting not working. I can see the saved network in the list but deleting it does not work. I havent yet rooted, im on latest stock and the bootloader is locked. Tried factory reset but same problem occurs.
Searching web and Oneplus forums pointed that there is couple others having same problems but no solution from anyone.
Do anyone have had any of this kind of problem and how did you solve it?
I like Oxygen OS itself but rooting is a must! after i can give logs or stuff if needed!

Update to latest oxygen os or open beta, if updating won't fix your problem then perform a factory reset.

Like I said I tried factory reset but did not help unfortunately I updated to open beta 38 last night but did not help either. 'm gonna try open bootloader and flash the firmware again completely and see.

[Q] Obtaining ip...

Hello!
I've been searching for a long time about this issue but I haven't found aan answer...
I have a rooted GN with original rom and recovery. Yesterday I wiped the phone and now I'm not able to connect to any wifi network.
The phone is always "obtaining ip...". And that's all.
I also have a Nexus S and one computer connected to my wifi and they are working fine.
I also tried to connect to another wifi and the result was the same..
Before yesterday I had no problem, even with the phone rooted.
My android version is 4.2.2.
I tried to reset my router (Netgear), tried all security options (open, wep, wap2, etc).
I have no mac filter... I think I already tried all the "logic" options but I always get the same
I start thinking the problem can be android 4.2but I don't know what is whatt I'm doing wrong.
Thank in advance for any help!
Best regards
Flash a factory build to your device to isolate it as software related.
I had a similar issue with a tplink router, now i have a asus and the issues are gone.

I downgraded to android 4.1 build factory and works. thanks
That's an odd problem.
You already downgraded, so there is no scope for trouble shooting.

WiFi not turning on?

Ok so a couple of days ago I installed a 4.0 ready radio on my galaxy s2 and then went on to install Jedi Knight 6 ROM (4.0.4 and radio is UVMC6) and after installation everything was working fine.. I was messing around for a while.. it worked today, I shut my phone off to charge it up real quick, and when I turned it back on my WiFi would not connect. Well not necessarly connect.. it just wont even turn on. When I go into settings and click WiFi, it just sits there saying, Turning WiFi on, and never changes.. I can't seem to imagine what could have happened to it, and I really dont wanna have to reinstall the ROM again because i just spent hours getting this one all set up to my liking...
Anyone got any ideas?
EDIT: BTW, I have tried many things.. Tried airplane mode to disable everything then turn it back on, obviously tried rebooting the phone, i have tried wiping cache in CWM recovery and also tried fix permissions in recovery (another topic said to try those..)
Nothing has worked so far, i'm about to try reflashing my radio, see if that works.. but I really really dont want to have to reflash my whole ROM.. So if anyone has any other ideas please help, i'll edit if the radio works..
EDIT 2: Reflashing the radio did nothing.. it's really wierd, the data, bt, gps.. all of it works fine, it's just the WiFi that's frozen turning on... cant get it to stop turning on and can't get it to actually turn on..
EDIT Final: Ok well, i guess nobody knows what might have been going on.. so I just wound up reflashing my ROM, which obviously fixed it.. i just had to lose all that time spent setting everything up... But oh well.. Kinda sucks nobody even tried to help..

+1 I'm going through the same thing now
I have been having this same issue as well. It started out as stock happening sporadically. One thread suggested rooting and removing my account. Problem still occurring. Tried flashing multiple ROMs and now WiFi hasn't connected at all always stuck at turning on. I have tried clear cache, fix permissions, as well as reinstalling ROM dirty and with factory reset. I'm hoping this isn't hardware failure because I just bought this phone used but it seems to be a reoccurring problem with others as well. Any NEW suggestions not given from quick Google/xda search?

I'd suggest to check your Wireless Access Point (modem or router) wireless settings for security, check and see if it's set to use WPA/WPA2, which is common on some modems/routers, change it to either WPA or WPA2 (preferred) not both, it's a known issue with WiFi networks and having it set to using both, I had the same problem before with my phone connecting to my WiFi.
Also if you use MAC Address Filtering on the modem/router, you should disable/clear that and let phone re-connect before enabling mac filtering again.

The problem I am having is not that it won't connect to a particular network. Wifi will not initialize on the device at all and is stuck in "Turning On..." state. I found more and more posts where people ended up having to send in to Samsung so I spoke with them and even though I purchased the phone used its thankfully still under warranty and they will be replacing it. The did not confirm whether or not it was a true known device issue but were quick to file the exchange for me.
sigh, me too!
Just started having this problem on 4.3.1
great.
In my case, I had to wipe system and data before reinstalling my ROM.
Though the only reason it was happening to me was because Beanstalk 4.4.2 didn't want to get past the splash screen when I tried to install it so I downgraded back to ICS 4.0.4 without wiping. Good luck getting this issue fixed. Also another kernel might fix thingz for you if your current one does not like your device.
I have a similar problem. After a while, WiFi gets disconnected. If I go in settings - wifi, i get the message "unfortunately, settings has stopped" and I can't get WiFi to work again until I reboot the phone. The Wifi works again for a couple of minutes then stops.
I have flashed various different ROM (CM11, PA) but keeps getting the exact same behavior.
I've rebooted in safe mode and I don't get the problem now.

Unable to start Wifi & Bluetooth

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

No Wi-Fi, no Bluetooth and no FM Radio [D855]

I'll try to give as much information as possible.
Yesterday I was surfing the internet and suddenly my phone froze and randomly restarted. After that I wasn't able to connect to wifi nor bluetooth. I was running android 6.0 with 30B modem, rooted and with TWRP. After that I flashed Modem from v21C Firmware. I don't know if doing such was responsible for the next thing, but my Wi-fi mac adress and bluetooth adress disappeared from Hardware information. Note that my IMEI information did not disappear.
After that I did a full factory reset with .TOT method. That didn't solve my problem. Tried upgrading to lollipop, did not work. I've done like 10 factory resets only today, I've tried to fix persist partition following this guide http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576, same results.
In 4.4.2 and 5.0(all versions I tried from lollipop), both wi-fi and bluetooth adresses showed up as anavailable. Sometimes after rebooting, my phone would connect to wi-fi and show my mac adress, and would crash after 30 seconds..
On 6.0,my mac-adress shows as 02:00:00:00:00:00 and bluetooth adress as unavailable.. Need some serious help here, tried so much stuff nothing worked..
I'll attach some screenshots that may be useful
Any questions and any tries to help me are highly welcome.
Enjoy 6.0 on your phones and thanks for reading :fingers-crossed:
-------------------------
Edit:
Adding some logs. Half a year passed, no solutions.
1 out of 100 reboots wifi works. I've gathered some logs of 1 of the moments wifi works. Hoping someone can figure something out. Tried lots of roms, nothing seems to work.
Forgot mentioning that both wifi and bluetooth show as trying to connect on notification bar, but when I go to settings and press on them, both say "turning on (wifi or bluetooth)" when the button is grayed out and off..
did you tried to use the cse flash in flashtool to fix this?

Did CSE flash, normal flash, TOT factory reset, wiping wifi's definitions.. Nothing seems to work :crying:
More info:
During the night, I removed the battery from the phone and booted my phone. After that Bluetooth would work, and Bluetooth adress would show up on "Hardware informations". Then, I turned off bluetooth and tried to put it back on. Bluetooth adress disappeared and my bluetooth would not turn on. Hope anyone helps..

Also, forgot to say that, if I try to turn on wi-fi, if I connect my phone to my computer, computer will recognize I attached something and will start charging the phone, but I won't be able to transfer items to my phone since it won't appear anywhere on my pc..

I think I found a solution but I can't test it since I'm having problems connecting my phone to my PC ( another problem appeared..)
May I ask yo to install busybox and try this on adb?
adb shell
su
busybox iplink show wlan0
and see if it shows your real adress, if it does
busybox ifconfig wlan0 hw ether (adress)
busybox iplink show wlan0

I don't have my phone with me, sent it to repairing. Any news?
I'm having a very similar issue. Wifi and bluetooth won't turn on and cycle. On some reboots, Wifi will turn on but the phone will shut down shortly thereafter. I've tries several different ROM's and can fix the Wifi, but no the power not the shutting down.

I'm having the exact same problem but a bit worst. I can't even turn my phone on. Phone came back from repairing, guy couldn't fix it. Tried some rom's, many "fixes" from the internet, nothing. Seems like the only way to solve this will be by hardware..
exactly same problem with my g3 too
even i was using stock 30b firmware and after one week of usage it suddenly crashed and stuck in bootloop hence downgraded to lollipop and tried all roms,factory reset,different modems etc but still not fixed
waiting badly for an solution
I'm having pretty much the same problem, along with overheating and screen fading. I'm using stock Lollipop, never rooted. I've tried a factory reset and a new battery with no results.
Any solutions?
Guys I've sent my phone to a local repair shop and they said they took it to LG's official partner.. I've been waiting for a while and it doesn't look good.. A friend of mine bought a g3 recently. I suspect this problem comes from a corrupted or missing file. I'll ask him to help me on checking files if the local shop can't find a way to fix the phone. If everything fails, the only possible solution I see is a new main board or a new phone..
lg g3

what is the exact problem ur facing in ur phone.

Wi-fi issue, kepps scanning but cant connect

Hello, bought a nexus 5x a few days ago and after a security update (april one i guess) wifi stoped working. It keeps scanning for networks but cant find any. Bluetooth, gsm, everything else works fine.
Tried to reset network settings, reset to factory settings, flashed all the updates from the google servers, flash a custom rom, delete "persist" folder, all with no succes, wifi just dont works. If anyone has any idea what to do, i'm ready.
Thanks in advance
Flash latest factory images
Sent from my Nexus 5X using Tapatalk
Hey, did that, flashed all the factory images.
Sent from my Nexus 6P using XDA-Developers mobile app
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.
