Hi..I currently have three computers all wireless located individually in three rooms of our home..the connection is find on these computers which are serviced by broadband using a 54 Mbps on 2.4 GHz frequency wireless firewall router (Trendnet) located in the den of our home...I have tried to re-locate the wireless router as central as possible relative to these three computers however, the computer in the room that is closest to this router gets faster response time than the others...is there a range booster or something I can connect to my wireless router to strengthen the signal so that these other computers can also get quicker internet response?
