Thank you for the question. Can we please try a remote session to work on the problem you are having?
Were you previously able to connect using the computer Wifi to your Wifi router?
Did anything lead up this?
What happens when you try to connect?
next time i switched on there was no responce.
a small red cross appears in the conection icon.
PACKARD BELL. ALL IN ONE DESKTOP.
Ok please try removing this Wifi network connection from your Windows 7 computer and then letting your computer rediscover it.
When you left click your Wifi network you will be asked for the network username & password.
After entering this you will have joined your Wifi network again. Is the red cross still there?
