So here is my set up. I have a computer DIRECTLY connected to broadband internet. A Linksys router takes a cable to a D-link router and from there a cable goes into the back of another computer(my computer). Here is the problem. For some reason my card does not recognize if have an internet cable plugged into it. Also, seomtimes device manager slaps a yellow caution sign onto the card, but that will go away after I install and reinstall the card. There is another cable going from the back of the D-Link into my playstation and I get online just FINE with the playstation. Any suggestions on how to fix this WOULD be great. Thanks
You probably either have a FAULTY/incompatible ethernet card, or faulty drivers. Try downloading the latest drivers for your ethernet card from the manufacturer's website. If installing them doesn't improve the situation, replacing the network card (quite cheap to do) might.And why two routers?So, you have two routers between your broadband modem and your computer. Is that right?

I believe that's not going to work unless certain changes are made in the settings one or both routers. I don't RECALL the details. I know D-Link has some info on this on their website.
