windows 8.1 is the odd duck with charm-bar deviance's.

guide 1, page 15
what I do is press windows key, to make w8
act normal. (like all other non w8 do)
then step
Tap or click the wireless network icon
to go farther you need a wifi router at home
and know your broadcasted SSID wifi name (yours)
then your login credentials.
if you router has WPS ,this is more easy. (button marked WPS)
