I have an Inspiron 5100 with a Broadcom 440x 10/100 adapter.  When I have a network cable plugged into my laptop, it recognizes that a cable is there and says that I'm connected to the LAN, but when I try to use any internet programs like Internet Explorer or anything like that nature, it says that it can't find the server.  All of my internet programs do similar things.  It was working fine last week, but this past Friday is when it stopped working, and I've been trying to get it to work eversince.  I've used the IP config utility through the command prompt.  I have a Dell Dimension desktop that almost 6 years old now, and that connects to the internet just fine with the same setup as the Inspiron 5100.  If anyone could offer some help as to my situation, it would be greatly appreciated.
