Hi Leilajoycey,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Pavilion g6-1247sa Notebook and cannot connect to the wireless network. Here is a link to troubleshoot the wireless.
The first thing I would do it reset the router(unplug and wait a second or two and plug it back in) and restart the computer.
Hope this helps.
Thanks.
