Vista - Stops locating networks, after being used continually or idled

I have a Compaq Presario C552US, I just purchased two days ago. It's running
Windows Vista Basic. Sometimes after using it continually or when idled for
a couple of hours, it wont locate networks anymore. I know I'm within range
of networks when this happens, and my wireless button is always turned on.
It sits and thinks for a while, and then says something along the lines of
"Can't find any networks" It even does this inside my home, where I know with
100% certainity there is a network there. I have to restart the computer and
then all of a sudden it finds networks again. I'm having to restart the
computer all the time, and I'm sure that's not good for it. Any idea what's
going on with it?

You may need to re-configure the power management. Or this search result may help,
