lenovo B40-30 odd WI-FI problem

I have an odd WiFi problem with my B40-30 (3+ yrs old laptop problem from very start). Initially running Windows 8 upgraded to Windows 10 home 64 bit (full reinstall).


Problem: the WiFi suddenly hiccups and dies and then comes back. I put a USB WiFi dongle but same behaviour.

But I connect the USB to my mobile to use as a tethered modem which actually goes thru the wifi and it works like a breeze.


I havent taken it to a service centre as it may be complicated to explain / diagonise and I dont want to mess the system 


Device manager does not show any disabled hardware 

Driver used is Qualcomm Atheros AR956x Wireless Network Adapter

Driver Files athw8x.sys and vwifibus.sys version


any ideas how to resolve this issue

Hi Sanjayminni!


Welcome to community forums,


If the issue happens even when using a WiFi dongle and all WiFi driver is updated, this is a possible motherboard issue.


Best to consult with a third party technician for better diagnosis.
