upstream router and the Internet port on your Linksys router .
3. Run Cisco Connect on each computer that you want to connect to
the Linksys router . Each computer needs either a wired or wireless
connection to the Linksys router . For more information, see “How to
The computers that are connected to the Linksys router are now on the same
