I have a Dell Inspiron B120 laptop with a Broadcom 440x 10/100 network card for the Ethernet connection.  I had no problems connecting to my DSL modem and the Internet (was even plug-and-play) until today.  The Ethernet light on the DSL modem does NOT light up when I connect my laptop to it.

I know that my DSL modem still works, because my desktop connects to it just fine - the Ethernet light on the DSL modem does come on, and my connection works.  So the DSL modem works.

The Ethernet cable isn't at fault, either.  Even when I move the Ethernet cable connection from my desktop to my laptop, my laptop still won't connect with the DSL modem.

Given that I can safely rule out the DSL modem and Ethernet cable as culprits, does this mean the NIC card in my laptop is dead?  If I need to replace the NIC card, what should I buy, and where can I buy it?  On the one hand, I'd be inclined to get the same NIC card.  On the other hand, I'm not happy that this one died on me in less than 4 years.
