in the box down by the clock there is a icon that is for the network. if you right click on the icon and open profiles then click the refresh button this should do what you wish. I have a couple of questions which may be pointless but here goes anyway. you say you connect the laptop to the pc, how do you do that is it by a ethernet cable or usb. Second is if you have a modem have you considered a wireless router. you could connect the pc hardwire to the router and the laptop to the wireless the advantage is that you should not encounter the problem again.
