UPDATE:
I did factory restore from google servers. Still no working wifi!
SO: the wifi modul not working... Good buy nexus 5x I had a great time....

[Q] Unable to connect to secured wifi networks.

Hello!
This began about a month ago. I was using Lollipop 5.0 and had absolutely no problems with my phone until one day, all of a sudden I wasn't able to connect to my home wifi network. I enter the password and it just says saved,secured. Then I discovered I was unable to connect to any secured wifi network. I tried soft and hard restarting my phone, restarting my router, forgetting my home network and trying to reconnect, I tried clearing my Google services frame work data, and still nothing.
I finally decided to downgrade to Kit Kat and did a factory reset and loaded a stock version; no dice, I still was not able to connect to secured wifi networks. I tried rooting my device and deleting wpa_supplicants.conf, still back to square one.
I find that I am able to connect to unsecured wifi networks.
Im at my wits end, I really do not know what to do. Please help.

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
Good luck!

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.

Thanks in advance
Flash latest factory images

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.

WiFi no longer connects

So, tried to upgrade to the Oreo Beta. That went bad. So, restored and encrypted and was going to try again. But, after rebooting and restore, WiFi no longer will connect. Keeps disabling.
Try to forget, reconnect...nothing.
WiFi AP is good, other devices connecting. Restarted AP all good...so no idea.
Anybody have this before?
Update:
Nothing would work. Just completely wiped/formated everything, running Oreo Beta now, WiFi started working. Must have been something with firmware etc..who knows.

Device forgets all saved WiFi passwords when toggling it off and on again

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.
