I currently have a Linksys WRT54G version 6 with 2 computers wired using cable modem located on 2nd floor. My home theater is on 1st floor at opposite end of house. Would like to be able to have my Sony S550 DVD access the internet, the Sony has to be hooked up to the devise by Ethernet cable, also thinking of purchasing a devise to stream video to TV and use my lap top in this room. I guess a wireless gaming adapter or wireless access point would work for the DVD but wouldn't I have to change the Ethernet cable if I wanted to use other devises? . The street price of Linksys gaming or access point, devises are $60 to $70. At that price I could purchase a new router. I am asking if my current WRT54G version 6 could be used as a wireless gaming adapter and then I would purchase a new wireless N router to take the place of my current WRT54G. Would/could the 2 wireless routers communicate with each other and do what it is I want done? If so, how difficult is it to accomplish that?
