"I have the same router on my 4 computer network. Every time this happens I end up replacing the router (3 times all under warranty) a quick fix that helps until the next reboot is offered on Linksys website . Linksys.com follow the tech support leads to easy connect.
Good Luck"

I followed the instructions, it established the connection on the main computer. then I just hit repair on the two computers downstairs, and it updated the connections, it all works! Id like to thank everyone that helped, thank you very much.
