USAFRet - I am using 1 of the 4 router ports to go to the switch. As part of the debugging process, I just found out that the problem is slightly different than what I originally posted. When I connect my laptop to the switch directly with a cable, I can access the internet, so the switch seems to be doing its job. What is most baffling is that if I try to connect the laptop to the ethernet wall jack in my office, (when the switch is connected to the router), it is unable to access the internet. Which led me to believe that maybe it was a problem with the internal cabling which feeds from the central point in the house into the office and other rooms... However, when I take the switch out of the equation and connect the other end of the office cable directly into the router (essentially taking the switch out of play), and then connect to the wall jack in the office, everything seems to work fine ! So am very confused as to why the connection via the wall jack works directly with the router, and not when it is through the switch..!
