Prostar Computer :
I hate to say it, but it sounds like your wireless LAN card has failed. You've done pretty much everything you can to rule out software issues at this point.
If you're comfortable replacing it yourself, replacement cards (the same make & model) can be found online.
Thank's again for your help.
Finaly (today) i was trying to install all the win 10 updates, and i found that "realtek semiconductor corp. - net - 7/13/2017 12:00:00 am - 2023.59.601.2017" failed all time, i did a quick search in google and downloaded the last version from this site (
