Can't switch on WiFi

Hi guys!
I had problems with my wifi and I found a solution online saying that I should delete these three folders:
/data/misc/wifi
/data/misc/dhcp
/etc/wifi
I done that and now the phone's WiFi cannot be switched on anymore (WiFi switch stays gray and cannot be turned on).
Is there anything I can do other than a factory reset or flashing phone?
Can anyone zip up those 3 folders and post them here?
Thanks !
Phone info:
Model: Note 4 N910C
Android version: 5.1.1
Phone is rooted.

Can someone please post these folders?

Do you have any custom recovery (CWM,TWRP,etc) ?
Don`t you have any backup (Nandroid) ?
If so , then restore the back up through the recovery.
If , not , then I think you`ve to flash stock firmware through Odin (at your own risk).

I have the same problem but i didnt deleted any folder. Just stopped working and i cant switch on wifi. Weird is that today when i was browsing google play from 4g data plan the window with wireless networks appeared and i was able to connect a wireless network. After 10 second was off again and the switch button is grey again. I am on stock 6.0.1 and not rooted. I think is a hardware problem probably the wifi+bt chip has some unsoldered pad to motherboard.

I don't think it is hardware problem. Restart and fully charge your phone and try to turn on wifi. Maybe you have some application (battery saver and similar) that prevent you to turn on wifi.

I'd take it into a Samsung Service Center and let them have a look at it. As there is obviously nothing you can do to repair the problem yourself.

I will try to repair it tonight by myself because i dont have guarantee anymore. I will post here the result maybe we can repair this error.
i tried last night . I heated the wifi chip until i was able to move it slowly and the let it cool. Surprise after reasembly wifi was working ok all night and today at work i saw the same problem .
I think we must change the wifi chip but i cannot find it to buy... Any help ? Anyone knows an app or something similar to see if the chip is detected by motherboard? I think it must be detected if the mac adress of the wifi board is displayed...

Unfortunately there doesn't seem to be any fix for this. You'll need to send it back to Huawei for service. I just went through that myself a couple of weeks ago.

Hotspot - Internet connection not working

I do get a Hotspot, can connect fine, but there is no Internet access on the connected device.
Does anyone else have the same problem?

A2017U here with no issues.
Sent from my ZTE A2017U using Tapatalk

Anyone with A2017 can confirm that it is working?

I recently upgraded my A2017G from B03 to B08. When I ran B03, the hotspot feature worked fine for me. After the upgrade I see the same behaviour as mentioned here. Client device connects to the hotspot, but the client can't access the internet as the Axon does not seem to route. I upgraded to B09 and this still did not fix this issue. I will try to revert to B06 and eventually to B03 to see if it brings back the functionality...
-EDIT-
I reverted back to B06 and the hotspot function is working again!
.

Assuming you are rooted.
Add to your build.prop - net.tethering.noprovisioning=true
Then open terminal emulator and type:
Su - enter (grant access)
settings put global tether_dun_required 0
By doing these two changes I have never had an issue hotspot or being billed for it. If you are not rooted and have hotspot on your plan, I would suggest trying an open connection (no password on the hotspot) at least to see if it works then continue troubleshooting.

Not rooted.... And no success with the open WiFi..
Weird.

Ya I've had some laptops just not want to work. I would try another device (phone, laptop, etc) and see if anything will work. Also try the troubleshooting wizard in Windows but doubt it will help.

Yep, could be device specific.. I'm rooted & tablet or PC connects just fine, but my Grace Internet Radio receiver, which connects easily to my router will not connect to the hotspot.

Can confirm that the same behavior is there with an A2017G. Apparently not with all devices.
This article sound exactly like my issue (and has a possible fix):
http://www.geektalks.org/fix-zte-axon-7-wifi-hotspot-tethering-no-internet-access-issue/

Works perfectly for me, couldn't live without it.
I use it regularly to work on the go connecting my laptop and to share my data with my son (iPhone 5s).
Great speeds too.
A2017G, stock B08.

I had the same problem along with being unable to receive MMS. Once I updated MMS setting "APN type" to "default,supl,mms", both started function correctly. Hope this helps.

This is a common issue with mobiles with Chinese software and for Chinese market. There should not be problems with G and U models. My is G version and everything works ok. I used to use Lenovo mobiles and have had the same problem. It can be fixed by DF Tethering Fix application from Play Store. There is one condition - you have to root your mobile.
Regards

I've got the same problem with my ZTE Axon 7. I tried to set the phone back into the B03 version but i don't know how to fix that? Can you tell me how i can revert the system on the ZTE from a later version b09 to an earlier version b06 or b03? Can you guide me trough this proces? I hope so.
Thank you very much

Everyone to fix this issue you have to flash the bootstack zip for your version of the ROM,

I've tried everything except this.
So I flash bootstack and I was able to connect my old phone using tether, said ZTE on wifi icon. But then it jumped to a different wifi. So I forced it to my ZTE and now all it does is trying to obtain IP address.....Over and over. Please help if possible, thanks in advance.

Open More/Cellular network/Access Point name. Choose your active access point and edit APN type. If there is anything there add dun in the end of line. Mine looks like this: default, supl, dun.

Do you have Dual SIM?
I have A2017 (China) LineageOS 14.1 20170424 and also experienced Hotspot issues with 2nd SIM.
The 2nd SIM is setup for data.
I get a DHCP address, but can't connect to the internet.
I suspect a routing/iptables issues.
I've managed to get it working with this workaround:
Connect to the hotspot (DHCP). if you don't have internet access go to "Set-Up Wi-Fi hotspot" and press save.
This re-saves the connection and internet access is fixed - works for me.

Oneplus 5 does not connect to wifi networks

Hello!
My Oneplus 5 does not connect to any wifi networks. It is able to see all wifi networks in the range, and is also able to save the network if the password entered is correct, however, it won't actually connect to any network that is saved. I have tried using advanced options while connecting to a network to change from DHCP to Static settings, but it still won't connect to any network. I have also tried changing the wifi band frequencies (2.4 and 5 Ghz individually) to connect to a network but that too does not help. Mobile Data and carrier signal on the other hand work flawlessly, and so does bluetooth connectivity, NFC and personal hotspot (which is why I am very confused). I should also mention that when it fails to connect to a saved wifi network, it occassionally displays "Disabled" under the network SSID (replacing "Saved").
I have changed 3 different ROMs (LOS, stock OOS and No Limits ROM, even replaced the stock kernel with blu_spark r69 when I tried using No Limits and stock OOS to try and see if that fixed the problem), but the phone just won't connect to any detected/saved network using any of those ROMs. I have reverted it fully back to stock now (OOS 4.5.14 and stock kernel and stock recovery) and am still having the same problem.
Sorry if this issue has been solved before and if I am reposting something, but I really need this fixed ASAP and am not able to find a working solution after searching the forums and googling the whole day. Please help me! Thanks!
Edit: finally fixed the problem thanks to Ivints and PeterGuru. Check out the post that Ivints linked below (especially the comments in page 2 of the same)

I'm having exactly the same problem that the guy who started that post had. I'll let you know when I fix it and everything goes well again! Thanks again, bud!

if you want to stay on Nougat look for the O2N revert flash file it's in the Oxygen 5 beta threads that will let you get back to a nougat based rom.
The Oreo update touched other partitions outside of /system so those wifi drivers don't work with Nougat anymore

I see... I'll look for that thread and get the flash file! thanks! I'm currently using xXx's No Limits 9.2 OB03 ROM with bluspark 3.2.1 recovery and bluspark r77 (Oneplus 5). The only reason that I feel like reverting back to Nougat is that I want to be able to use Xposed again. So i guess I have that option in hand not too! Thanks, bud!

Hello there my friends, i have a problem with my op5
its about wifi: it doesn t see my wifi anymore. idk why
it s been connected to this wifi 2 years ,even after switching roms kernels, firmwares
and now , it doesnt see the wifi no more, actually it sees it, in `Saved` section, but when i press on it to connect
it says ` not in the area` but my other op6 its connected no problem
and i even tried through qr code, it says ` check ur connection and try again`

Just one add-on cause I was just a few minutes away from formatting my data. My OP5 unlocked rooted, rest stock, wasnt connecting to my home wifis (2,4ghz and 5ghz). I flashed a full ota zip. I deleted wifi bluetooth via backups settings.
But I found out that connecting to an iphone hotspot worked. So I entered manually the network SSID + password although the same network name was already in my wifi list (with marking: "saved"). I then clicked on the second "new" same wifi and it directly connected to my home wifi. Same happened to the 5ghz network. I then deleted the old 2 ones.
I have no idea why this happened, I only tried to get VoLTE/Wifi Call running with the magisk module. This might changed sth but I dont get the connection here since there should be no interference...

Nokia 6(TA-1000) cellular network not work after Android Oreo

I just upgrade my Nokia 6(TA-1000) to official Android 8.0.0 (Oreo).
Then my Cellular network won't work anymore.
I live in Hong Kong, using sim card service "CMHK".
I think it is LTE/WCDMA mode.
Tried "*#*#4636#*#*" and changing the settings.
But the connection always shown IPv4: Failed(2)
The phone notification show it is connected and running 3G network.
But the upload/download speed is always 0KB/s.
Reset to factory setting already.
Before upgrade Android everything work fine.
Anyone have the same problems?
Now, what can i do....?
It seems I can't even downgrade my Android.
Only, have to wait for next update and hope it will fixed?
I think i am screwed.

I use official update.
All firmware should be correct?
BTW, I get a new sim card from ISP but cellular network still not working.
Also, tried both sim card slot 1 and slot 2 nothing work.
May be new system not compatible with my SIM card service only which is "CMHK" aka "中國移動香港".
Hope next update will fix that...

NOKIA 6
hi,
i updated my nokia 6 TA-1000 to oreo update.
i faced many issues like lte not working.
in battery saver mode launcher is stopping suddenly.
it is not detecting the sim correctly.
i didnt get network signals correctly.
Then i tried to hard reset my mobile ,after complete reset and after rebooting it stopped at language selection,i clicked lets go many times but it is not working .it got stucked there.
is there anyway to get rid of it.i asked for nokia chat support but they are asking me to take mobile to nearest service center.
if there is any solution please guide me with it .thank you in advance.

I just turn off the cellular network yesterday.
After I wake up from bed, my phone Google service can not connect from wifi(can't use email, Google store).
BUT! After reinsert my sim card and turn back on cellular network, everything working now.
Both 4G cellular and Google service all good.
May be some part of the network is cached.
So, if you encounter this problem just turn off cellular network and wait.

It seems that, the old slot 1 cached your sim card.
So, you change to slot 2 work, but you can't use SD card.
And I found that if you wait a long time the cache will clear.
You can try to insert sim card back to slot 1 after 1-2 days.

The only option was left to flash stock firmware, but as it updated to oreo, its bootloader has also been updated so I will suggest you to wait for official oreo firmware to release, please don't try to downgrade your device for now, it can brick your device very badly, keep patience, if any solution will come out, we will definitely tell you

Yes, I got it fixed...
1) Just turn off your cellular network.
2) Wait for 1-2 days.
3) Turn on your cellular network again, it should work.

How can I off cellular network. Will keeping it in flight mode helps?

Thank you for raising this question. My phone got the same problem. I am just wondering if I should send it to maintenance center but I guess they will just do reset.
And by saying "turn off cellular network and wait for 1-2 days", do you mean by just turning off the data usage, or turning it to flight mode/ turning the phone.
