I just installed a Linksys E3000 wireless Router in an upstairs office where I run 2 Desktops and a wireless laptop. I need to connect a third desktop in another part of the house and also run hardwire to an outbuilding. If I run an Ethernet cable from the New E3000 to another Linksys hardwired Cable Router, and from there connect the third desktop and outbuilding, will all these work OK. Simply put, will connecting the Wireless router to the Cable router be OK????
