Detailed description:
The issue goes like this,
The device, Realtek RTL8723BE Wireless LAN 802.11n PCI-E NIC randomly, and suddenly stops functioning. and does not respond to troubleshoot. Even after trying the administrator troubleshoot, and trying a restart, it does not work.
i have to connect my phone and do usb tethering in it to use internet. (dont have an extra lan cable at home)
When i uninstall the device driver, and uninstall the device, and restart the laptop, it works when it starts again. it works for a while and then again stops working.
i dont understand what the issue can be.....i guess it can be that the connections are loose....or dust has settled on them...or the device has some hardware issues...
i have attached photos of the problem that the trouble shooter shows and the problem that the device manager shows.
Please comment, reply, help me out with what i can replacing the wifi internal device....or using an external adaptor...(my laptop has only 2 usb ports and 1 c type port) please suggest what i can do....
and yes, i have tried to update drivers from windows, from asus site, from realtek site, but nothing works for a long time and the issue continues.
only solution that works for a few hours, (the solution which i perform and i can connect to wifi from laptop) is that, manually uninstalling the driver, and the device. then restarting the laptop and then while restarting it installs the driver automatically. (which apparently is the latest version..2018 version) and then this works for a few hours before disconnecting suddenly.

Hello Kavan,

Have you double check if your BIOS is updated as well?

If possible, you may consider to use an external wifi adapter for cross check,

or please send your device to service center for further examinaiton.

Thank you.

main culprit is lan realtek system driver and its .inf files.

install the old version driver , download from asus site or from realtek official website

I did update the BIOS and then it worked for a while...and stopped again.
Will try with the older driver of now its the latest one...and currently its working....but after a while it may may stop after i restart...anything can happen 😅
Will try that with older driver if it happens.
if nothing works, i might have to consider getting the internal card changed...
lets see how it goes
Thanks a lot. Stay safe🙂
