Or another option is to bring in a unidirectional antenna. As anything is possible to be doing, you can easily find stuffs of that sort.
Your PS3 antenna is located by the right hand side, so be sure that you never block it with any thing else, coverings, books or just anything that blocks free signal flow. Same is the case with your router, be sure nothing obstacles the antenna and also be sure that no interference occurs. Routers for home use are shipped with a 2.4 GHz frequency, any device operating in the similar frequency can reduce the router signal strength, so keep off such devices or change your frequency.
