My daughter's Vostro 3450 has recently developed an issue that it loses connection to the wifi AP - the wifi strength icon has the circle turning when this happens.  It is not the wifi ap as there are other devices nearby that do not exhibit this behavior.  On one occasion when this happened the laptop was beeping according to my daughter.  Should I log a service call or is there something I can look at to determine what is happening? 

Thanks for your assistance.
