I supposed because a little virus I have lost the automatic wifi connection.
Each time I reinitiated the system , fortunately not very often, I have to introduce again the password for wifi connection - even with automated connection marked - ever and ever again...
While I try to discover the deep reason in windows 8.1 for this disconfiguration I would like to have a script in the desktop to login with ease in the wifi connection.
Is it possible and how ?
Best Regards
