Things You'll Need
Instructions
Position the PS3 so that there are as few obstructions around it as possible. Other metallic or electronic devices can interfere with the Wi-Fi signal. Especially move cordless phones or other devices that use Wi-Fi as they function on the same radio bandwidth as the PS3's Wi-Fi.
Set your PS3 on its narrow left edge. Bend the cardstock so that it forms a semicircle around the back and sides of the PS3 about six inches away from the console at the back and eight inches away on either side.
Tape the open end of the cardstock to the front of the PS3 so that the cardstock holds its curved shape. Don't put any tape over the disc slot on the Playstation. Cut any excess cardstock.
Tape aluminium foil to the back side of the cardstock. This will focus the Wi-Fi signal on your PS3 and boost your signal.
