Is there any WiFi Error solution?

I went through google, here, and other android blogs and where I found people who've had a similar problem to mine, there seemed to be no concrete solution.
What I'm talking about is literally in front of my eyes, though I didn't know the extent at the time, the wifi \ bluetooth died. I was listening to a podcast and the wifi turned off. I had no problems that led to this, no issues with the ROM (Energy) and anything else to indicate anything was wrong. So after turning it on it would just say error, and that was it.
Like other posters who've brought this up, I cleared cache and dalvik, went to stock, went to other backups from different ROMS, and still nothing. So is there anything concrete anyone here knows about? Thanks in advance!

So as to fix this problem,some people suggest to do a Factory reset.But, it is completely unnecessary.Instead you can try the following methods, which where tested by me successfully.
1. Dial *#*#526#*#* to reload the wifi driver.If it doesn’t work, restart your phone and dial it once gain.It will work for sure.
2.There is an app “Wifi-Fixer” from android market,which claims to be fix this problem.But seriously,it hadn’t worked for my mobile phone(Samsung Galaxy Ace).But,
if you are interested, can download and try it here.
For HTC users, I have a pretty good trick which works very well.
When you have obtaining IP address problem,
1.Turn off wifi.
2.Open “Allshare”, then you will be asked to connect to a wifi network.
3.Then select the wifi network that you need to connect from the list opened.
Magically, you will be connected without any extra effort.This works 100% sure without fail.
If that doesnt work try this:
1.Dial *#*#526#*#*.Then a message will be shown “Driver loading Successful”.
2.Now Start the WiFi, it should work.
If the message “Driver Loading Unsuccessful” is shown, follow these steps:
1. Dial *#*#526#*#* again and click options button on your phone.
2. Select Rx test.
3. Select Channel >9 .
4. Click Start and exit.
5 . After some time, turn on the wifi.It should work.

It is possible you've fried your wireless card.
Can you test Bluetooth calling?
If enough heat built up for a long enough period of time both could be affected.
ie charging while on wifi using Bluetooth and a heavy CPU workload is a perfect recipe.

Okay Diablo, thanks for the suggestions but of course, it didn't work. So many times I read these threads where people are having trouble for one reason or the other and nothing ever seems to work... Now I'm that guy.
So like I said, I would dial those numbers and nothing would come up. Now I did try wifi fixer and it really looked it was doing something, but again, nothing happened.
And 9h0S7, I'm fearing you may be right... I've read the bluetooth and wifi are on the same antenna, and I can't get the bluetooth working either. A friend of mine checked the board and everything looked fine so visually speaking nothing seemed corroded or messed up in anyway.
Anyway, thank you both for your help and I continue to hope this can be fixed!

Help! No Wifi connection now...
I had the "Wifi Error" problem with my Samsung Galaxy Ace device, so tried to follow the procedure described with Allshare. It didn't work, and now my device is not able to connect via wifi in any way! I've tried restarting the phone many times and dialling the code to reload the driver, I tried to download Wifi fixer, but no method works. The phone "sees" the Wifi network, tries to get the IP address and then disconnects. I don't know what to do... I'm desperate...:crying: :crying: :crying:

[Q] HELP! My Mobile Data Will Not Stay On After Opening Service Mode!

So last night, I was reading through some posts here and elsewhere about the MTP software not properly loading onto PC's and I was having the same issue. One thread said to go into Service Mode by dialing *#7284# and changing the USB options. Well, as soon as I went into Service Mode, I lost my 4GLTE signal. It would pop up as if connected and then immediately disappear. I restarted the phone several times, removed both the SIM and the SD card, and was still having the issue. I called myself from my landline and the call went through, I was able to answer it, but the icon still kept disappearing. I can also still send texts. I tried going into apps and using them with wifi off and they won't stay connected to the internet when the icon disappears.
So I chalked it up and decided to factory reset today because I've had the phone for almost 2 years now and I figured it would help with some other issues I was having. Well, after I reset it, it is still giving me the same issue, although it seems to stay connected a little longer now before cutting out. On wifi, everything works fine, but once I shut it off, I lose my connectivity. I didn't touch any other settings in Service Mode and it was as soon as it went into Service Mode that I saw the icon disappear. Then I thought it may be a SIM issue, but I don't have another mini-sim to try or a phone that I can try my SIM in. I'm running Simple Mobile on my phone currently. It isn't rooted. Now I'm mortified that I won't be able to do anything with my phone unless it's on wifi... *sigh*
Has anyone else had a similar issue??? Did you find a way to fix it? Any other suggestions that I may try? I don't want to deal with trying to root right now because If I brick it completely I'm going to scream...
Help?
P.S. - I apologize if this is posted elsewhere on here, but I wasn't able to find a similar issue when i searched. If you have a link to another post here, then please drop it on me... also, I'm fairly tech savvy. I just have no idea why this would happen without me actually making any changes.

Possible radio issue?

After doing some digging, I'm thinking there's an issue with my radio? Is there a way to easily flash the radio? I'm thinking that may fix whatever is keeping it from staying connected. I have noticed that in the last few hours it has been staying on longer, and when I connected it to my laptop, it stayed on for the most-part while connected. This is a weird issue, I am really wondering if anyone has had it. I will keep updating and if I find a solution it will be here, just in case this happens to anyone else. I'm hoping one of you helps me though. :victory:
Either way, i have uninstalled (and now reinstalled Kies and the USB drivers). Going to install ADB and Odin as well and keep reading up... back to work I go!

**FIXED**
I have no idea how, but the issue has fixed itself. I had my provider (Simple Mobile) cycle my SIM card and that seems to have fixed the problem. I will never know what actually happened I guess... but should this happen to you, I would suggest having your provider do the same thing.

WIFI Scan Doesn’t Find Any SSID’s

Wi-Fi works with all existing, configured AP's. It can’t find new ones during scans. I was in a motel all last week and couldn’t detect the local Wi-Fi. I could manually add it and it would work. I don’t know when it started but it was working not too long ago and I haven’t made any major changes to the phone recently. I loaded Wi-Fi scan app and it detects and connects to mine and my neighbor’s AP's so I suspect it’s not the hardware. Settings look good. I disabled AppOps and unfroze anything that might be related. I can't boot to safe mode. I think it's because of exposed. https://forum.xda-developers.com/xposed/tool-samsung-xposed-safe-mode-disabler-t3652781
SM910V, rooted, 5.1.1
Thanks, Geno

I thought I'd bump this. The only thing I did since the original post is to TWRP the phone back to an earlier date before I set it up to my preferences. It worked there but there's to many custom setups to start again from there. The WIFI manager app does what I need and was quick and easy.

Phone Restarts at the Most Random Times

Hey everyone! I was having phone troubles and was wondering if anyone could help solve them. I lurk more than I post on the forums, so forgive me if I make any mistakes.
My phone is an AT&T Galaxy Note 5 (of course) 32GB variant on stock 7.0. For what ever reason, my phone restarts with out reason and sometimes does it multiple times a day. It usually happens when I am on Wi-Fi, or the phone is looking for Wi-Fi. At first, I thought it was due to 3rd party apps trying to access data with low signal, but the problem still occurs after multiple factory resets. The phone doesn't restart as much when I turn Wi-Fi off, but the problem still occurs with Data.
The problem began around the time I updated my phone to Android 7.0 when AT&T released the update. I usually keep Wi-Fi, Bluetooth, Location, and Sync enabled if that helps. I also clear the cache partition after each security update.
I also believe that it has something to do with the Wi-Fi because even listening to music sometimes with Wi-Fi enabled, causes the audio to freeze or stutter. I read on a post that this might be due to Wi-Fi scanning or Bluetooth Scanning for location purposes, but the phone still restarts with those options disabled. I am unsure of what else to do besides just living with the problem. I took it to AT&T to see if they could help, but just wanted to sell me a new phone.
If anyone could help, I would greatly appreciate it. Thanks for reading and for the help in advance!

This is most commonly a botched upgrade and the way to repair it is to flash the entire current firmware to the device again which will delete all your personal files, photos, contacts, text messages, music, app data and anything else you have stored on the phone. Most of the time you can download your firmware from a link provided through this site, be weary of any other source of downloads links besides xda-developers.com!! Your AT&T store can flash the entire firmware to your phone again for you while retaining your data, but if you are holding out on upgrading so you can gain root this will defeat your efforts. For 99% of the people you should just take your phone to an AT&T store.
There's a chance that the next upgrade will repair your phone by replacing the problematic file but you'd be lucky to have that serendipitous outcome.

I was about to take it to an AT&T store, but I turned off Data Saver mode and did the latest update, and everything has been fine since. It's really the weirdest thing but I'm glad nothing too much had to be done to fix it. Thanks for the help and reply though!

SIM card recognized but no service

TL;DR
Moto Z2 Play - XT1710-07
The phone recognizes the SIM card but there is no signal (no service). Tried several things, including flashing a custom ROM. I'm considering buying a new motherboard and changing it myself, but first want to know if anyone knows more about this issue or has an idea/suggestion.
Edit: As an added bonus, something that only now I realized. Now when I charge it, it gets EXTREMELY hot. Like I-can't-even-use-it hot. I used to use the phone while charging all the time, but now I can't even hold it. Seems like the problem is when it tries go past 80% charge. It gets super slow, keeps trying and gets hot. Now I don't know if it's a software problem caused by the various flashings or if it's something that would remain even after swapping the motherboard.
Edit 2: I did a full discharge of the phone and recharged it while turned off. It seems to have normalized the battery problem
Edit 3: RIP. I tried to remove the screen before deciding about buying a new board. In the process, I ended up tearing the digitizer flat cable apart. Now I don't think it's worth it buying both a new screen and a motherboard.
The full story and things I've tried
My phone was working all nice and dandy until it stopped having signal/service. Wifi works normally, but anything related to the SIM card doesn't, like phone calls or mobile data.
A list of things I've tried somewhat in order (both of time and of complexity):
* My SIM in another phone: it works normally, so the problem is not the SIM itself
* Another SIM in my phone: it doesn't work, so the problem is definitely the phone
* Using the second SIM slot
* Changing "Preferred Network Type" between the available ones (4G, 3G, 2G, including Enhanced 4G LTE Mode on and off): this one and the next two items don't really make sense to me, since these options seem to be only related to mobile data (4G/3G internet) connection, not to phone calls which is also not working, but I tried them anyway
* Manually selecting the network: Errors with "Selected network unavailable" and, after trying to register for a while, toasts another error saying "Can't connect to the network, try again later"
* Manually selecting the APN: Tried both selecting between the two options available and manually adding an APN by googling the correct info for my carrier
* Simply booting into fastboot and restarting bootloader: a video on YouTube claimed that it was a temporary solution and that I'd need to do it every time it lost signal. But it didn't even work the first time
* Disabling CQATest and then restarting bootloader (and also clearing its data/cache and removing its permissions): a lot of videos on YouTube claimed this was a solution, including for other Motorola phones. Apparently CQATest prevents the phone from working properly in some scenarios. But I think only when you de-google your phone? Not sure. All I know is that it didn't work either
* Using the phone connected to the wall charger: I think this was another YouTube suggestion, and it actually worked for a few minutes. But I guess it was just a coincidence, as it never worked again
Now for some more... "forceful" attempts:
* Factory Reset: Not sure where I saw this suggestion, but it was pretty much the next logical step. Gathered courage, backed up all my data, etc, aaand... nothing again
* Flashing another ROM: Guess it was here at XDA that I read that it was a problem with Motorola's stock ROM. That, paired with my belief that it could still be related to CQATest being installed, I again gathered more courage to flash a custom ROM. I chose LineageOS and found out that it was no longer supported, but decided to install the last official release. I also read that the problem was the Pie modem firmware, so it all seemed to be going fine since the last official release is Oreo 8.1. I flashed it and BAM it worked! ... for a few minutes and never again. I messed around with LineageOS, tried some of the previous things again, but nothing.
Then, I tried to restore my TWRP backup but it didn't work. So I searched a bit more and downloaded the Stock Pie ROM, flashed it, and closed the bootloader. And then I realized the restore probably didn't work since my backup was made using Pie and my phone was on Oreo. Maybe some files/partitions were missing? Also, when I was creating my TWRP backups, I tried creating a full system image backup but it kept erroring. Only later I realized the problem was that the USB Drive was FAT32 and the full system image was bigger than 4GB. Oh, well, now I know.
So now that I'm with my phone pretty much back on square one, I take it to an authorized repair shop. The clerk said that it was a common problem, and that sometimes it could be solved "by software" and that they'd try that. The other option was to change the whole motherboard, which they didn't do because it was "not worth it" and "almost the full price of a new phone". After two days, my suspicions were confirmed: they didn't fix it with their "by software" attempt. At least I didn't have to pay anything.
When I got the phone back, I put the SIM in again and it showed the icon as if there was signal. But when I tried to call someone, the signal disappeared again. I tried searching a bit more, went through all pages of Q&A here at XDA forums and there were like 3 posts regarding loss of signal. All without any response. On YouTube, I found some videos offering a suspicious .bat file. Upon inspection, it merely erased the modemst1 and modemst2 partitions and then wiped user data and cache. I tried it, nothing to lose. Also didn't work.
Now I'm contemplating a few options:
By watching some disassembly videos, I saw that, when opened, the phone has some parts that act like antennas. I thought that maybe those were not properly connected to the board? Maybe they got dislodged during a fall? Seems unlikely tho, since they are screwed in. I searched for a new motherboard to buy and it's a reasonable price. But I'm afraid it'll have the same problem (or develop it in a short time) since I can't find anywhere what the true cause of the problem is.
Another option is to just give up, buy a new phone and use this one as if it was a "small tablet" lol
So, do you guys have any other suggestions or ideas as to what might be the problem? Maybe a tip like "solder a wire to this spot to create a make-do antenna"? I don't really know where else to search.
If not, thanks anyway for those who read it all
