This reply maybe a years late-its 2015.
But in case some people get this problem which I had.
Correction on a wireless network W8.1 as follows,
Search/locate Network Connection in "charms"
Right click on Wi Fi - select DISABLE-Wait a minute then
Rt click Wi Fi again to ENABLE.
sign in to your internet provider when you see your SSID.
Also a note if your printer nor receiving wirelessly to cpu
Turn ON Bluetooth.
I hope this helps.
