hello, i have a 2wire DSL wireless router from ATT&T. wireless works great ofcourse near the router like maybe 50 feet or so away. however we have another desktop machine many rooms away and i need to get the wireless range to reach to the other rooms. its a fairly big house. i have tried the linksys range booster, but it was a waste of my time and money. is there a better commercial router that can send the signal farther or a stronger signal to get through all the walls? what are you suggestions?
