I would appreciate any help setting up a new computer on our home network. We have a Linksys wireless B 2.4 GHZ Broadband Router. Connected to a Comcast cable modem. I attached the Linksys wireless G 2.4 GHZ USB network adapter to the new desk-top PC and I have a message that reads "Local Area Connection, A network cable is unplugged." I am on the Internet now, from a wireless network connection from Linksys on my laptop. Any suggestions would be greatly appreciated.
