No network/internet after SATA PCI card install?

[shud]

Hey guys -

Pretty new to Linux and Ubuntu in general.

I wanted to throw a bunch of my drives onto my Ubuntu box, so I plugged them in, turned it on, and it mounted them no problem (all NTFS).

Now, to do this on my fairly new mobo, I had to throw in a PCI SATA/IDE card since my mobo only has one IDE port.

At some point I noticed that I couldn't get any internet connection. I'm getting an IP and the right subnet, gateway, and Comcast DNS servers from my router.

Somewhat funny, my VMware machines all have internet access!

Is this some kind of IRQ conflict with the card? I have no idea about network config files.

EDIT: Update...I can ping the gateway (192.168.1.1) without any issue, but I can't ping any other computers on the network. I'm so lost.
