When I boot into gentoo, I get the message(s)

Comcast uses DHCP, however the IP configuration from Comcast gets saved to your router, not your PC. For all Comcast knows, you have one PC directly connected to the cable modem. A router is a beautiful thing.

If it worked fine on the LiveCD, then it's not a driver issue. Did you forget to emerge dhcpcd? What happens when you type "net-setup eth0" after chrooting to gentoo from the CD, or booting from the HDD?

Also a look in your /etc/conf.d/net might be helpful

Apparently the program net-setup doesn't exist on my computer, only on the LiveCd. What package should I emerge to fix this?

/etc/conf.d/net

What happens when you run the command "dhcpcd"?

Hi,
From what has been said I would check the following in this order:

Check the driver is loaded for your network card, this is done automatically when you boot from the livecd but not once you boot into your own installation.
normally you would add the driver to load in /etc/modules.autoload.d/kernel-2.6
see the section 7.e http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=7

I do not know your ISP /router however the most likely scenario is:
Your router gets an IP from the ISP using dhcp.
You plug your pc('s) into ports on the router and dependant on your router configuration you maybe able to use dhcp to get a dynamic ip for your pc OR choose a static range of ip's (Dependant on your router )

Personally I use a static IP for my pc's to connect to my router. In which case you would use a config file similar to KhenemetSobek posted.
If you decide to use dhcp you change the config to iface_eth0="dhcp"
see section 8.b http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=8#doc_chap2

Once you have taken these stages, the command 'ifconfig eth0' should show a properly configured interface, if not you have a problem which needs further investigating.

Assuming the above worked and you have configured name servers in /etc/resolv.conf you should be able to connect to the internet.

Let us know how you get on.

OB.

I doubt that its a configuration issue. did you build the kernel yourself or use the genkernel utility? Sounds to me like you didnt compile that module to support your NIC. You can check this by: boot using the livecd and run lsmod. Boot normally and use the same command then compare the results. If you can post the output of lsmod, and lspci | grep ethernet here that would be helpful.

I have the same problem. No internet from the hard drive, but can from the livecd.
Originally I used genkernel but then I reemerge gentoo-source and recompiled the kernel. I'm going through a linksys wireless B router, but connected through ethernet. I did emerge dhcpcd. My etc/conf.d/net only has one line uncommented.

This should help you out.

In my kernel I have <*> National Semiconducto DP8381x Series PCI
Still no go. I can also not get to my /etc/modules.autoload.d/kernel-2.4. In /etc/modules.autoload.d I can see that there is a kernel-2.4 from ls-a; but when I try to go to it it says it can't find the directory.
