Wifi and Bluetooth stopped working under Android - Teclast X98 Air 3G

Dear Community,
I would like to call for your kind help because I have got completely lost considering an issue that I have faced. Suddenly the wifi and bluetooth stopped working under Android on my tablet. Everything is factory standard, I haven't modified anything and even applied factory reset from the Android menu and hard reset from recovery mode. No change.
Networks are visible but it stops with the message "Connecting" and if I set a fixed IP, it connects but no data is transmitted. In case of bluetooth, I'm unable to enable it.
It is a strange issue because it works OK under Windows 10 that gets all the regular updates. I started to experiment with old wifi and bluetooth drivers to see if there was any conflict with drivers but I didn't manage to learn anything by that.
I am completely confused because I have had this tablet for a year and it suddenly started to have this problem. I thought the reset would solve it and was stunned to see that it didn't.
Would you please kind and try to help me out with some advice?
Any feedback would be much appreciated!
Kind regards,
Viktor

What's your model ?

Wifi turning off when phone idle or sleeping

I've got an annoying problem with my phone where the Wifi turns off when my phone is idle or asleep. This means my WhatsApp for Web disconnects and also my Moto Connect plays up too.
I've got the same problem at home, work and parents house so can't be an issue with all 3 networks. The keep wifi on during sleep option is set to Always before anyone mentions this to me.
Phone is running Lollipop 5.0 in the UK and is NOT rooted.
I noticed it doesn't happen when the phone is charging though.
Any ideas?
Right I've now tried changing the Sleep setting to Never but get the same problem.
Also tried connecting to the router via WPS but no luck.
Router is a Superhub 2. I've ruled out that it's the Superhub as I have a Samsung Galaxy S4 Mini that is running fine without a single drop out.
Definitely something Moto X related.
I've also tried on both the 2.4GHz and 5GHz bands with same results!
Try looking within the WiFi settings on the phone. Mine has this
. Added photo
Sent from my HTC One using XDA Free mobile app
Mine is identical to yours other than the fact that I don't have the wifi optimization option.
Right I've just cleared the cache as instructed by Motorola support.
Still have the same problem even after clearing cache.
Ok I can confirm that the issue goes away when in safe mode.
This is starting to piss me off as I don't have any way of checking if it's an app affecting my wifi disconnections!!!
I've finally found and fixed the problem myself!!
I decided to turn my bluetooth on (even though it wasn't connected to any bluetooth devices). This seems to stop the phone from causing the wifi to go to sleep!
It seems like it's a bug in the Moto X Lollipop firmware. How do I report bugs to Motorola??
It's funny how most say it's apps that cause strange behaviour but for me it's been the actual Android firmware each time I've ever had an issue!
I hope it gets fixed soon.

It's a known bug of 5.0, and already fixed for 5.1. Source, at the "Bug fixes section".
Great that you found a workarround.
Cheers!
Manuel.
Hey glad to know it's a well known bug. The work around still doesn't work. It still keeps disconnecting all the time! Driving me mad!! If the 5.1 update doesn't fix it for me, I'll need to try and get a refund and go for something else. Shame as I really like the Moto X but I can't live with an issue as stupid as this!
I'm not sure Motorola are aware of this issue at all. See their comment below from one of their support staff I'm speaking to now:
Santhosh: We have not received any reports regarding Wi-FI issue after the Android Lollipop update but please give me a moment I will provide the solution for this issue.
His solution for the issue was to get me to do a factory reset lol. I already did this when I first got updated to Lollipop!!
Going to try doing another one now to see if it actually makes any difference. Then will install a few apps at a time or something.
I am connected to WiFi just about all of time, and I have never experienced this.
Right I've done a factory reset and started completely afresh with none of my data or apps restored. WiFi has been solid; I've not had a single drop out!
I'm going to install just a couple of apps at a time and keep an eye out if the issue comes back until I find the culprit.
Hi
My phone was perfect (until now) with the WIFI since november 2014 even after I upgraded it to 5.0
But today, it suddenly starts with this problem by itself. so I restored it to factory defaults with no luck, I installed a new firmware, and still has the bug.
So, why it shows up until now by itself without any mod, app or update?
Sorry for my English.
Today I upgraded it to 5.1 and the issue persists
I had to back to stock 4.4.4. and now my wifi has been fixed so far, working good without interruption until now.
I hope this has fix the problem from sourse, and I'll wait a few days to upgrade it again.
EDIT: Has been a month since my downgrade to 4.4.4. and my WIFI still rocks.
Just want to say that I'm having the same issue since the update to 5.1. Wifi is set to be always on during sleep, but I regularly wake up my phone only to find it connected to 4G, and switching to wifi a few seconds after waking up.
I'm on a locked bootloader (unrooted of course). I did a full reset after the update...
I'm sorry to say that I've seen more little glitches since 5.1 than anything I noticed on 5.0.
EDIT: another issue I'm having is the stock mail client not syncing saying that there is no network connection. My exchange account (push) works fine however...
Just to say the issue has started for me too since the update to 5.1.
I've done 2 factory resets but no luck trying to fix this very annoying problem.
Motorola have asked me to send my phone in for repair so I'll try that and see what happens.

No connection issue /w lg wear urbane

Hey. So I've faced a kinda strange issue. The watch seems to be connected to the phone, everything is okay. I get notifications etc. However, once i try to use "Ok, Google", it seems that simultaniosly the watch looses it's connection and i get that red circle trying to hear me out and, finally, no connection with crossed cloud logo. This situation occurs when wifi is turned off\automatic\forced to my local wifi. My cellphone is Xiaomi mi note. Please advise if any1 of you had the same problem and how can it be solved.

Factory reset = restore default from the menu, i presume?
Okay, the solution to the issue occured in the manner i did not expect it to be. I should have activated the voice recognition thru BT devices. (google->settings->voice). However, since i own a chinese phone - that topic may rise on phones without preinstalled g-apps (and google search bar accordingly). So in case any1 has that problem - check that bar.

No. The problem occurs randomly, plus I swap firmwares on my phone, so there is none "stable" source of problems. On the other hand i believe that it happens less nowadays. mb android_wear.app did something to this, or watch firmware.

I have look everywhere but seems like is no solution for it. I'm not sure if flash with custom room would be a way. It might be a hardware problem. I can't sent my to Sony because there is not warranty anymore.

Ok, my warranty expired too! I also tried software repair and still not working and i now see that Bluetooth also is not working.
Hey guys. I fixed this on my phone about a month ago. So far no one has commented if it has helped them or not, but here is my post again. Let me know if it helps.
I had this problem on my Z3c for a while (as well as no wifi or bluetooth). My device is well out of warranty. I received a RMA number last week to send it in in hopes that it would be an affordable fix. I was getting it ready to send out today and decided to try a couple more things.
As others have said, I went in to the diagnostics and test the WiFi (passed) Bluetooth (passed) and GPS (failed). I then decided to test WiFi and Bluetooth a couple more times to see if it would eventually fail. It never did. After that, I went to turn WiFi on manually and to my suprise.... it turned on! Bluetooth and GPS were also magically working.
Before this I had tried numerous factory resets, diferent android versions, different roms (without unlocking the bootloader) with no success. I'm not sure exactly what happened, but hopefully it can work for some of you!

I have exactly the same problem but only one thing is different that my Bluetooth is working. There only problem is wifi. I belive that is no hardware problem. There must be some kind of glitch in software where you accidentally doing this things jumped over. I have tried your tip. No success. Im going to do this every day to see if I have luck. My Bluetooth and wifi passing test every time GPS is failing.

Tell me if you fixed it. I'm still having no luck.
Yes, please do post back your results. I'm not sure if what I did was a fluke of what, but I was shocked when I saw my WiFi turn on. Almost every other post I have seen about this either stops getting replies or the OP sent it in for repair numerous times.

I have done exactly the same things like you described. No luck. Strange my Bluetooth is working only wifi can't be switch on. GPS is failing on test like yours. What has the GPS to do with wifi? I don't know if there is any connection.

I forgot to mention I was on the latest factory lollipop image. I'm not sure what you are on. Are both WiFi and Bluetooth passing the tests?
I'm not sure if they are connected or not.

When I was trying to root, I ended up using KingRoot and replacing it with SuperUser afterwards. None of the other methods seemed to work for me.
Ok. I have rooted my phone with giefroot. Very simple. You only follow the guide. But now I have rooted phone and gone to to root Explorer and can't find the file I should delete.

Sorry, I can't help with that. I don't see it on my phone either. I have no idea what that folder is or what it does either.
F*ck, I have same problem, wifi won't turn on. Few times after phone was turned off for long time it worked but mostly just stuck. Bluetooth works so can I be sure it's not a hardware problem?

Note 5 nougat Bluetooth issues

Hello everyone,
So I've been having some troubles with Bluetooth on two devices running nougat, and I haven't really found any good resolutions.
I've been practicing app development lately and was originally Bluetoothing the apk to my phones to test out (email or cord has been the obvious solution but I get obsessive and wanted to figure out why bt would not work). Weird thing is it was working fine for a couple attempts then it would not work. Laptop is an msi apache, it will connect and transfer to other devices running marshmallow and cyanogenmod no problem. But my s6 and note 5 on nougat will not work. It will attempt to send, time out and say device disconnected AND THEN I'll get the prompt on my phone asking to accept the file, but of course it's already disconnected.
Tried clearing cache, resetting network connections, disabling Wi-Fi, re pairing devices on the phones.
On my laptop I changed the device type from 128bit encryption to 40-58 or what ever it was.
Repaired, restarted, tried changing support services to a local service login type, reinstalled the bt driver... I'm assuming it's the phone but just wanted to list a couple things I tried.
Any ideas or just an android 7.0 issue?
Thanks.
Edit- first post and I put it in the wrong section, sorry about that! Should be in qa
What rom are you using? Try another perhaps, I've had lots of issues with Bluetooth over the years due to buggy roms.
Just installed latest firmware (ERC1) on my Note 5 SM-N920T and bt don't work plz help. Just came off a wipe ESF lost IMEI LOST ALL carrier signal no sim card detected. Finally got it back and no bluetooh.
Something similar happens to me

WiFi/Bluetooth not turning on

Hello,
A few months ago I noticed I had trouble to switching WiFi/Bluetooth on on my xperia z3+ (lineage OS 14.1) : when I slide on the WiFi slider, it load "Turning WiFi on..." until it switch back to off by itself. I don't think it's because of software update because I actually stayed on the same firmware for a while where it initially worked then started having this issue. Updating didn't solve it.
What I tried :
-Google the issue, I saw other xperia users having the same problem on different models but I didn't manage to find a fix
-Safe mode
-Wipe everything and reinstalling fresh rom
-Tapping the WiFi button furiously for a while
I'm having internet problems at home, but I can't manage to share LTE to my computer successfully, and I suspect both issues to be linked.
I tought I should ask for help before officially declaring the phone physically dead, so here I am.
Thanks for reading, any answer is much appreciated. Sorry for the long post despite it just saying "WiFi bug plz help".
