My current set up is as follows: (-> means hardwired) ISP -> Modem -> LINKSYS Wireless Router(wireless 1) -> Windows Computer -> Printer . Then also hardwired to the LYNKSYS wireless router is my airport express(wireless 2). When I am downstairs and connected to wireless 1 (lynksys) my mac finds the windows computer on the network and I am able to print, however, when I am connected to wireless 2 (airport) I cant find the network or printer. Is there some network setting i can change to fix this? thanks.
