Wired network connection
For wired networks, connect one end of an Ethernet cable (purchased 
separately) to the Ethernet connector on your computer, and then connect the 
other end to the network router or broadband modem. Consult your ISP for 
detailed setup instructions.
NOTE: Broadband modem and router installation procedures vary 
depending on the manufacturer. Follow the manufacturer’s instructions.
