I have a wireless router at one end of my house, and a laptop that will not pick up the signal at the other end of the house. Is there anything i can do to boost the signal to the laptop? im getting really tired of havin to sit close enough to the the wall to plug this biotch in. help me out. is there anything i could put midway between the router and the laptop that would pick up the wireless signal, amplify it, and rebroadcast it?
