My Toshiba L355-S7915 laptop is not staying connected to the wireless network at my house? - toshiba network camerawife

I have a Toshiba L355-S7915 and not connected to my home wireless network. It is a password, but I checked and I have forgotten where true. Sometimes it connects, and if so, then the connection drops within a few minutes. I need some ideas of what I should do to resolve the problem. Please help.
