Problems with network connection after installation

[jsowoc]

I have tried to install Gentoo several times, but this is the first time I have gotten to the stage of a working system... sort of.

I booted into the live CD, the Internet worked, and I did a stage 3 installation. I reboot into my installed system, and the Internet does not work.
How can I find out what I need to set in my kernel or other files to have it working?

Additional (possibly relevant) information:
- I have a Marvel Yukon Gigabit Ethernet card: its driver is marked as "experimental" when compiling the kernel.
- I connect to the Internet via a firewall which normally assigns me an IP address through DHCP.
- I have followed all the relevant instructions in the manual regarding the installation of hdcpcd, setting a hostname etc.
- The Internet works on the live CD, but a genkernel (from what I have heard) is slower than a regular kernel as it needs to autodetect hardware - I don't go switching my motherboard (with integrated network) on a daily basis.

As most of you know it is quite difficult to use a Gentoo system without Internet access, so any help would be greatly appreciated.

Have you searched the forums for Marvel Yukon Gigabit Ethernet to see what others have experienced? I'd try Installing Gentoo, this forum, and perhaps Networking & Security.

Try using a static IP -- just choose an unused DHCP address, or an IP from the appropriate network. There have been problems with some drivers getting DHCP addresses. I forget why.

If that doesn't work, change how the NIC driver is handled in the kernel. If you have it set as a module, compile it into the kernel. If its compiled into the kernel, try it as a module.

Thank you.

I searched for my card, and I found that you have to load the module. Here is what happened:
- I was told that if I didn't need something in order to load my operating system, it was better to compile it as a module, so I did - just about everything that could be a module was.
- I was not told that one had to explicitly load the modules in order for the kernel to use them. I was under the impression that links to these modules were made in the kernel automatically, and it would load them on-demand whenever it needed a module.

What I did was add these 7 characters: "sk98lin" to the file /etc/modules.autoload.d/kernel-2.6
The module was loaded on startup, eth0 properly configured, and the world is a very happy place now.

Thank you once again... now I'm off to figuring out how to get a gui on there - I want to turn the machine into a CS Source dedicated server.
