Adding hardware to debian

I thought you said you put the same network card back in and it would not work. How come you think the issue is to do with different MAC addresses?

Also is the router that connects your LAN to your ISP in NAT or bridged mode?

mmm, sorry i probably didnt explain this very well....

Let me try one more time. hopefully this will validate my MAC address theory.

I have 2 computers and no router. Computer W was the computer that hooked to my modem and to the internet with no problems. Computer L was originally setup on a LAN at my work. The next place I tried to use computer L was in my apt. with no router, but I couldnt get an IP, and thus couldnt do anything...so when i learned that some ISP's will make a note which MAC address is using a specific IP i realized that if i hooked computer L up to my modem the ISP would see a different MAC address and therefore give me no internet. So as soon as I changed the MAC address on computer L to match the MAC address on computer W it worked fine.

Does that make sense?

All clear now, Cody! Glad to hear it's all working OK. Some ISPs with the MAC address restrictions can allow up to five different MAC addresses. Obviously if you've got a router you can bypass the problem as most broddband routers have a MAC address cloning option.
