Hello, This is my first thread in XDA DEVELOPERS.
My Nexus 5x's wifi is not connecting. 4 months ago, my phone boot looped . And I don't have any warranty. I tried every possible way to bring it back but failed. I factory reset then performed a rescue OTA Which was tough to do because the phone was boot looped. But I didn't give up. I contacted the Chinese Repairman(Mr. Huang Jinhui) via WeChat(the one Cathair2906 mentioned in his 4GB RAM upgrade article). I sent my phone to China. And the phone was fixed + the RAM also upgraded from 2GB to 4GB :highfive:. He sent me a video in WeChat that my phone has been fixed and he mentioned that there is an account lock. In his video, The WIFI was connected to his network(not even the caution mark in wifi signal). I am very happy with that. But the Chinese man couldn't go to the home screen as the phone was reset(I performed a rescue OTA after the phone was bricked that's why). My email & password was needed. But in China, Google server is disabled so he can't bypass FRP even if I give him my email & password. While everything is available in Shenzhen, China, I told him to buy me a new battery of my phone and charger and cable. He changed the battery and send me a clip. Everything was fine. But when I got my phone in my hand and tried to go next, I couldn't connect it to any WiFi Network:crying::crying: . It load and then "Unable to connect" caution appeared:crying:. My phone is in Android 7.1.2 with June Security Patch Level. So after watching some youtube videos on how to bypass FRP lock, I followed some steps and went to settings menu via Talkback option. Checked the phone memory, it shows 3.6GB Ram :angel:, that's fine. Then went to wifi option and tried to connect but still failed. Tried WPS push button, didn't work . Then one of my friends told me that since the battery has been changed, the time and date has been reset & wifi won't be connected if there is a major difference in time. I checked the date & time and it was not correct. Then I was hopeful and relaxed that if I set the time and date correctly, the wifi will be connected.
I set the current time & date from settings and tried to connect it to my wifi network......................... Still, I failed :crying:. Turned it off and on then tried again.......... still, it doesn't connect. No "Authentication Error" message appears. In WIFI Settings menu it shows just "Saved" instead of "Connected"
It's not like that my phone can't search WIFI. Everything is okay, WIFI can be turned off & on. It can search WIFI Networks. All okay, just one problem, it is not connecting.
I can't bypass the FRP lock if I can't connect my phone to WIFI. I'm facing bad time after bad time. I am so near that I am finally gonna use my beloved Nexus 5X again still I cannot because of the new found problem "Not connecting to wifi".
If anyone can help me, I will be really very very grateful.
Thanks

So I got a Galaxy Tab 3 for free with my new Galaxy S5 yesterday. And on the notification bar there is a prompt saying preparing network. I have full bars on the signal but have no connection to the network. I tried rebooting, turning on airplane mode and trying to reboot the signal. But have no luck.
Is there anything that I can try to fix this? The Tab is stock and I haven't changed anything yet...
Any help would be great!!
Which tab 3 model?
Are you on the "right" network? Does you network have a hidden SSID? Are you using any security on the network? Check the network settings on your PC and copy them to the tab. If you are not sure, then open your network and see if the tab connects. If so, then you can close the network again.
I have the same issue but mine is working all networks. It started when I tried to connect to a new wifi at a wing place and the icon has been on ever since.
Same problem
So no one has any info or any suggestions? Nothing? Also I'm on Sprint.
I havent figured out anything , I have tried messing with sync and wifi options and nothing has changed.
I have looked at all the "Tab 3" devices since you did not indicate what model you have. With that in mind the search is very broad and data found could/could not be affecting your connectivity. But this is what I found.
All Tab 3, except Tab 3 Lite 7, use 802.11 a/b/g/n WLAN Standards. The Tab 3 Lite 7 only has 802.11 b/g/n. Why? I don't know.
So, make sure that your location has one of the three, 802.11 b/g/n working. You tab should auto acquire unless you have a setting that is specifically looking for a unique channel. Confirm all your parameters and the parameters of the WiFi source.
tab 3 prepping service solved
Ok so got 2 tab 3s from sprint today and same issue. To resolve this.......they are not activated! Run on wifi and go to settings and at the bottom left it will show a small phone icon and say activate this device. Click on that and let the live activation happen. The tab 3 will then reset and function on sprint networks!
Ok so that takes care of it initially and then it comes back on switching to and from wifi. You can get rid of the icon by going into the app manager, select all apps, and force stop samsung dm. Looks like it is a samsung software issue to me!
Man, the folks at Sprint aren't even aware of the issue yet. My Tab3 just sat there and wouldn't activate or connect at power on. So I have to skip all setup and go to activate in settings and it activated. Tried a factory restore so I could do setup again and no connection again and the preparing network problem. Switching to CDMA works. On the phone with support for like 30 minutes and they couldn't see my device on the network at all even while on LTE. Thanks for service reference. I was going to return this unit until I saw it was a software issue. It makes for a nasty setup/activation with no wifi around.
Sometimes activation fails and just gives a LTE error, sometimes it fails and sends data usage stats. When it completes it posts a backup pin and phone number. I'm guessing this happens with store pickups because they let it update on powering it up and that broken service starts messing things up.
Go to settings and then to activate this device and as soon as it starts to try and activate its self press the volume down 4 times and then you will see a screen that says IQTHiddenMenu....Scroll down to LTE mode and select it you will see a screen thatb has four boxes on it...select the one that says "enable LTE Mode" after you selct that then just hit back button a few times and let it try and activate again and this should fix your issues. You may have to do this twice. For the last 2 weeks this has been the only way we can activate anyones tablet is using this method, it has somehting to do with our Network not communicating properly with the Tablet.
Hope this helps.

Hidden screens. One has to love technology. So then one also has to ask, what else is the tablet doing that we do not know about? Reporting back to the mother ship?
Solution
So I had this same problem and I called sprint today and they were able to help me. THIS WILL RESET YOUR TAB AND YOU WILL LOSE EVERYTHING ON IT. Make sure to back up if you have anything important.
You have to open the calculator and type (+30012012732+ when the next screen pops up, type ##786#, the RTN menu will open, press Reset, it will ask you for your MSL, type it in and that will do it. Hope it helps.
BTW you will have to find a way to find your MSL as I never had to. I'm sure if you call your carrier they will give it to you once you tell them why you need it.

Looks like they are still having this issue. Mine was stuck on Preparing network. 3G and wifi worked, but no LTE or GPS. I did the hidden menu trick and now that all works, but I still have the "preparing network" notification. Is there any way to remove this? Could I do a ##RTN to clear network configs, then enable LTE through hidden menu, then activate?
Something to try that worked for me for the time being
I just thought I would share with anyone else having issues with the persistent Preparing Network message.
If you go to Settings>Activate Device and launch the Self Service application, there is a hidden menu accessible via the Menu Key, And you can then choose Reset Cellular Data.
Your device will then reboot, and it will go through Self Provisioning when it reboots.
I Had to do this twice, and 2nd time seems to have been the charm this time as the Preparing Network Message is gone!
Finally got rid of "Preparing Network"!

I spent 2 hours on with Sprint live chat, did a Kies reset, software hard reset, and everything else I could find...yet this solution was the simplest and the only one that actually worked!
Someone let Sprint support know how to fix their own device, please!
Thank you rastassjr, you saved me a trip to the Sprint store.
This is a common problem with an easy fix.* Long press the notification on the task manager.* A button will appear saying APP INFO.* Press that and you will see the app info page.* Clear the cache and data and more inportantly, deselect the notification checkmark.* Thats it!...*
OTA 4.4.2
Just got it on a new SG Tab3 7" and it cleared the "Preparing Network" icon. I had done a MSL reset yesterday and it had cleared it before I bricked it. I returned it, got a new one and it cleared it on its own after the 4.4.2 update.
Solved!
I solved mine after several weeks. First, oddly enough this error was preventing me from getting the 4.4.2 android update and the system said the operating system was up to date on 4.2. You need to download the samsung Kies program into your computer and perform a manual firmware update. The system will tell you that indeed you have the latest update but you'll do it any way. Once the OS is reinstalled, you will see that the PRL will be updated properly, which is the reazon for this problem. Then the system will allows you to receive the 4.4.2 upgrade which does not suffer from this problem. The key is to upgrade to android 4.4.2.
[Q] Wi-Fi keeps disconnecting and telling me that "Sign in is required" 2 days ago
Hi,
I have been looking in internet and didnt find any info about this kind of issue...hope somebody can help me with this.
The thing is that 2 days ago, when I return home I realized that my Wi-Fi wasnt connected, and in the Wi-Fi networks, under my Wi-Fi name I got the message "Sign-in is required" (which is weird because I neverd had to do that), after tapping on it and connect, it launches the message of "Sign in Wi-Fi network" and take me to the browser where it tries to open "google.es/?gws_rd=ssl " but nothing happens. Then after a couple of minutes I got disconnected with the message "this network has been disconnected. your sign-in timed out" and then goes again to the "sign in is required".
This issue only happens with my place Wi-Fi, at my office the phone connects to Wi-Fi and works like before and without any problem. And at my place it only affects to my Note 2, my gf S3 has no problem, some older devices like HTC Desire HD or Chacha also can connect to internet without problems, and the same goes for my laptop and ps3.
I tried changing network password, name and nothing. I removed the pass for my network and still the same...and after reseting the router no changes.
As far I remember the day the problems started I almost didnt use my phone, and didnt change any settings at all.
As for the device, I'm runing the original rom with android 4.3. On monday I had a small update throught Kies to "PDA:NE1 / PHONE:NE1 / CSC:NE1 (TGY)" and it worked perfectly.
any idea of what could be the problem?
thanks!
is there any solution to this?
I am having exactly the same problem with a brand new galaxy trend plus. since we bought it and brought it home yesterday I've searched all over the internet and tried almost every advice I found on problems with wifi connection, but with no success. the phone is running on android 4.2.2, and we have another phone and a tablet on 4.2.2 which never had any problems with the wifi.
I'm seeing what I think is this same issue on my Galaxy S5 on our corporate network. We have a captive portal page that needs to be accepted every few days, but once you accept once, you're good for that period of time. However, after that first captive portal, my phone is assuming that every time it connects there is a captive portal, so it isn't connecting automatically. If I forget the network and re-connect after I've hit the captive portal for that first time, it works as expected and will auto-reconnect if I roam to a different AP, etc.

need help!
Hi everybody,
Is there a solution for that problem? I did everythig that told in manу threads but still got nothing helpful. I found the Google developer's thread so it is suppossed to be not a bug but a special feature that no one can turn off.
I usually use pablic WiFi captive portals and nowhere I can set stable coonection on my Samsung Galaxy Tab 3 SM-T215.

It's described here: http://forum.xda-developers.com/showpost.php?p=58252752&postcount=38
"Sign into network" auto disconnect
The sign in autodisconnect function is caused by an internal android system app called Captiveportallogin. I used romtoolbox to freeze it and configured my network manually after a day of it auto disconnecting.
Hi everyone
Here's the situation. My Mum passed away in December very suddenly. Her Desire Z is really causing us trouble. She had a screen lock pattern set, which we haven't been able to guess.
We have reset her Google passwords (since we didn't know the old ones) but the device has WiFi turned off, and mobile data turned off, so when we try to login to one of her Google accounts to reset the screen lock it says "invalid username and password". For these reason I also can't send an unlock reset from Google device manager. I've obviously tried connecting it via a USB cable just to copy photos or any other files but it won't even do that while it's locked. It just doesn't seem to recognise that a USB cable is connected, unless it's plugged into a charger.
I've googled it at length and tried all sorts of tricks like calling the phone and clicking certain buttons, opening the keyboard at exactly the right moment, and so on. Unfortunately nothing has worked.
I know how to hard reset the device, but is there any way at all to get access to it before I do so?
Thanks so much for any help you can offer.
Hi All,
I own a LG G3 for past 1 yr and 4 months. Every thing was fine until last month when I accidentally dropped my phone and the display cracked. Of course, touch did not work. So last week I went to an authorized LG service center to change the whole display (which involves the process of taking out the motherboard and fixing it with another display. This means the whole frame is changed). He did this process in front of me only. After the change, everything works well except for a weird WIFI problem which I never faced before the screen was replaced.
The WIFI would frequently connect and disconnect. Even in the search list, all the SSIDs would be shown occasionally and sometimes won't show up at at all. Note again, this happens with all the potential WIFI connections around, Not only with mine. In short, the WIFI search results list won't be stable.
Even if my WIFI shows up in the list and I try to connect it will show - "saved"/"disconnected"/"Disabled" status. And yes, occasionally my WIFI gets connected and internet starts working. But not for too long. Prolly the connection lasts for 5-10 mins or so. All my other devices connect using the same AP and so i don't really have a doubt on my router AP.
I visited the authorized service center again. Without even having looked at the problem he says motherboard might be the problem, and asked me to change it. Even if i persist him to have a look at the problem, he won't . My last resort is XDA
The ways I tried.
1. Factory reset.
2. Flashed roms 21A and 20P (from scratch, erased all data and caches). Still No joy.
3. Tried forgetting the network and connecting again.
4. Toggle WiFi on and off
P.S : I also have another problem of SD card getting unmounted automatically and an error message pops up as "SD Card removed unexpectedly. Please unmount SDCard before removing to prevent", but immediately a toast message comes as SD card inserted. xx.xx GB space available. This keeps on happening in a loop until SD Card wouldn't show up in File manager at all. But, this problem was there for a long time even before the screen was replaced unlike the WiFi
problem which occurred only after the screen is replaced.
I really don't know what exactly is going on with my phone. Please let me know if any of you are familiar with these problems and have solved it. Would really save a huge money for me
Ladies and gentlemen of XDA, I have come before you today to admit to my defeat.
I have scoured the internet and tried all kinds of fixes and such and still no luck. So hopefully someone here can help me figure out what I'm missing.
I rooted both my husband's and my G955u. Both of our phones took the root well and were performing spectacularly. Then, randomly one day, something went glitchy with my phone. For some reason or another, I ended up putting the phone in airplane mode. For the life of me I can't remember why. The airplane mode icon would not turn back off. I turned the phone off and back on. Each time, I see the signal connection icon at the top, but there are no bars filling it. I cannot call, text, or use data unless I am connected to wifi.
I unrooted and flashed back to stock. No fix. I applied other root methods. Still no fix. Factory reset, cleared cache, took sim card out. Still nothing. Sim card works fine in other devices and no sim card will work in my phone. I have flashed each and every stock (2bqk5, 2bql1, 2brb1) with no luck. Took it all the way back down to 2bqk5 and allowed ota updates all the way to 2brb1. Still nothing.
Had an error for a while that when I entered recovery mode, it would either show no command or error followed by a screen saying that it had failed to unmount my EFS. That screen isn't showing up anymore, so I somehow fixed that. My IMEI and SN are both showing and are both correct. Phone network shows unknown. Mobile network shows state as connected. Mobile network type shows as IWLAN. Not Roaming, IMS registration status is on.
I have tried to flash the combined tar file of the modem and the Nonhlos.bin I extracted from my stock bql1 files. Flashed through Odin, still no fix.
I am at a total and complete loss. I don't know what else to try. Husband's root is still intact and working great. Can anyone help a noob figure out what I haven't done yet? I'm sure I'm missing something stupidly obvious. Any and all help is greatly appreciated and stories of your epicness will be told by my children's children of the time I was saved from the purgatory that is no cell service by the heroes of XDA.

Solved on my own. Downloaded the app shortcut master and launched secret menu #27663368378. Chose options 2,1,2,3,4 and restarted phone and I had network access again. Hooray!

Was just about to post about this, I too have been experiencing those issues, difference is my phone has not been rooted. Has the issue completely resolved?
Yes. That completely fixed my issues. You may not have to root to fix the issue if you can find the right secret code to access the service mode menu. But once the nv was restored, all was golden.
This is the screen you need to get to.
wow you went through all those downloads and flashes !
This was my first time ever rooting. I had no idea what I was doing or what exactly I needed to fix it I just knew I was pissed to high heaven and refusing to pay 200 for the replacement phone they said I needed.
Originally, geek squad tried to say that I had a chip failure due to the mipi device fail that showed up on menu *#0011#. But I didn't buy it. Turns out it wasn't a hardware issue. Just the NV data being a butt. Saved me 200 bucks. I'll take 50 million menus, flashes, and downloads over that anyway. That's what unlimited data and pdanet hotspot tether is for.
What did the menu have in it? I'm having a similar problem with not connecting to the network (unroot), but on my Galaxy S7. I've tried a million things, only to find out the "MIPI DEVICE FAILED".

I have the exact same issue on my S8+, MIPI device fail and can't get any network signal. On xfinity mobile here. I can't get that menu you're talking about, I downloaded Shortcut master and launch the menu you mentioned in your first post but it won't launch. Do I have to be rooted? Please help!
Mipi device failed. change the charging port and maybe it solves it. it has happened to me with a s7 and a note 8 and I have solved it by changing the loading port

I'm having this issue in this model and the menu "*#27663368378# Chose options 2,1,2,3,4 and restarted phone" didn't solve, it will be necessary to change or reconnect the charging port or other part?
