So i got a linksys WRT54GX2 wireless router and a Belkin Wireless G+ Router and 1 Cable modem. My house has 3 floors but my cable modem is on the top floor and my linksys router for sum reason cant reach the bottom floor desktop maybecause the network card is crapping out ro smth but i dont wana buy a new network card if i have 2 routers lying around. Soo what i want to do if its possible is 1 router top floor braodcasdting to the 3rd + 2nd floor and then hook up another router on the 2nd floor to broadcast to the bottom floor desktop. is there anyway to do this without hanging a cord from the top floor down to the 2nd floor router?? RECAP of what i want: router + cable modem on 3rd floor router on 2nd floor no wire hanging down the staircase from 3rd to 2nd floor router.
