Firstly NIC = Network Interface Card.
Secondly, by re-reading everything, can I assume you are on DSL? If so could you post the Make & Model of your DSL modem and router? At this point I am praying you don't have a Westel DSL modem.... I hate those f-ing things.
And lastly, when it comes to computer troubleshooting, the moment of "I have tried EVERYTHING" never comes. There is always something. Many years of tech support/troubleshooting has proven this to me.
