Heyah! So ive found an issue with my unit where if i open & close/move the display/lid to and fro in some cases the wifi disconnects and doesnt detect until i disable-reenable the driver in device manager
so this is probably a lose contact in hardware side? im on BIOS 2.12 if that helps (i dont think its software related)
if anyone tries what i did above and share your results that would be great.
its a temporary fix for me to disable-reenable the driver but its annoying whenever i move my laptop in some way ( THE DISPLAY/LID IN PARTICULAR)

if i dont touch/move it everything is fine until i do the mentioned thing. dont have any screenshots for this matter.

TL:DR found issue with wifi when opening closing moving display/lid can anyone reproduce this?

Have the Exact issue,
Its actually worse for me, WiFi adapter Randomly disconnects even if the laptop isnt being moved and sometimes disabling and re-enabling it doesn't work . You maybe right that it is a hardware issue (but why does it work rest of the time?), since a friend has the same laptop without these issues.
if you have found any solutions please keep us updated thanks!

Unfortunately clean install didn't work for me, I think I'll retry bios downgrade to 2.11
Got some work to do so I'll probably be very late. You can try the above driver solutions mentioned above by edy, didn't work for me--doesnt mean it wouldn't work for you. Good luck!

I would like to mention that my BIOS version is 2.11 ,the problem still exists. Ive tried the disabling the battery saver as mentioned ,the issue occurs less frequently now .

Do the following: copy the idhardware from the wireless network card and paste it in google! It will go some drivers and download the latest:

I've already tried different drivers and different bios. With different OS linuxmint, Manjaro, Ubuntu, windows 10.
The disconnection I meant was the device being totally unrecognized by laptop and showing red Cross symbol over Ethernet icon.

There is no option for wifi when this happens. The airplane mode also doesn't help with restarting the connection. It just picks up where we left off.
So manual enable wifi driver restarts the process and reconnects with device.
Hardware related it seems. I thought maybe others with same laptop has build quality issues like this.

What is the version of operational system? 1703, 1803 ou 1809?

1809. And as I said I've used many other OSes and it's the same.

I also want you to download the driverpack program that is in the signature to update the other notebook drivers! It is possible that some other driver is causing this problem!

Uncheck these programs:

havent tried this but i just found something else in the events log of driver. this was registered in it 2 days ago.

Device PCI\VEN_168C&DEV_003E&SUBSYS_080711AD&REV_32\4&d7fc392&0&000F had a problem starting.

Driver Name: netathr10x.inf
Class Guid: {4d36e972-e325-11ce-bfc1-08002be10318}
Service: Qcamain10x64
Lower Filters:
Upper Filters: vwifibus
Problem: 0x25
Problem Status: 0xC00000BB

EDIT: to my surprise its because of the Battery saver options in windows and linux for some reason.

yes ive tried things above fren, it seems like the battery saver disconnects wifi device as a whole. just confirmed that it works fine whatever i do if i have it disabled. thanks for your help. i just realized its not hardware issue. finally!!

Try this driver: https://www.ath-drivers.eu/qualcomm-atheros-download-drivers-nr-355-with-code-1939.html

OK! Try disabling this here:

Tried that too, sadly didn't fix the problem
Hey, thanks for trying to help me this far. I really appreciate it.
I have an external USB wifi adapter so I'll survive

I'll probably open my laptop later, I will see if I can do something about it then. Maybe buy a new inbuilt pcie adapter ..
Until then my 300mbps tplink is more than enough
Once again THANK YOU for trying to help!!

I think this is not a problem in the hardware, but rather some incompatibility between the driver and windows10! Are you using version 1803 or 1809 of windows 10?

windows 10 1809, okay i think ill do the driver update you mentioned above in a clean install. ill let you know in 12hrs or later. but the whole day today i didnt have any issue, ill report back later after a clean install of windows

There is no need to reinstall the operating system! Have you already tested with the driver I provided?

I would like to mention that my BIOS version is 2.11 ,the problem still exists. Ive tried the disabling the battery saver as mentioned ,the issue occurs less frequently now .

I've marked yours as the answer for now. Although it's effect is not 100% at least we know it does SOMETHING about the issue.

I've had less wifi disconnection after doing the same myself. But the problem still arises when I move my laptop in some way.

I don't think the issue is with my lid open close, may also be issue with the pcie connectivity. I've tried to beat my laptop up in some known places (yes torture) it's not pinpointing so.... If you are able to open your laptop up, check the wifi device connected to the board properly or lose connection.

I've read somewhere that the audio drivers conflict with the wlan drivers ,its seems to be true because sometimes my speaker starts crackling (i found a band-aid fix for that ) and my wifi stops working along with it. Is there any way for me to check whether that's the case?

i'll some other solutions too and keep this thread updated

OMG yeah, although I use my headphones like ALL THE TIME I hear that small jitter and my video stutters at that particular moment I can notice. I suddenly check my wifi just to see it fucced up.

Oh, I've noticed that before this thread too. That's why I tried to uninstall realtek driver and reinstall, tried without any audio drivers too. But IDK I didn't come to a correct conclusion. Maybe I should look more into this too.
