Hi, and thank you for your question. My name is ***** ***** I'll be assisting you today.
If you want to permanently disable the WIFI function on your laptop, please carry out the following steps:
First, press the Windows key and the R key together on your keyboard; this will bring up the RUN box.
There, type in services.msc and press ENTER.
In the Services window, scroll down to the "WLAN AutoConfig" service and right-click on it, and select Properties.
Set the Startup Type to Disabled and then STOP the service as well. This should do it.
