PostPosted: Thu May 25, 2006 1:29 am    Post subject: Setting Up NIC for Installation Reply with quote

I have a Dell Latitude D820.

My NIC is a Broadcom BCM5751M NetXtreme® Gigabit Ethernet Controller for Mobile PCs.

When I'm installing Gentoo, I can't connect to the internet, which means I can't view the Gentoo handbook.

Can anyone help me get this NIC set up?

So far, I've tried just pinging to see if it set it up for me, and then net-setup eth0, which didn't work.

There are a serie of commands you can use in order to properly configure your network device. I assume you're using dhcp in whatever network you're on:

1. Check what devices we have available
Code:

lspci


Look for a line starting with "Ethernet controller", see example below:

lspci wrote:

[...]
03:02.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139 C+ (rev 10)
[...]


2. Locate the device name

Code:

dmesg | grep "^eth[0-9]"


Output may look like this:

dmesg | grep '^eth[0-9]' wrote:

eth0: RealTek RTL8139 at 0xf887e400, 00:11:d8:83:5f:08, IRQ 225
eth0: Identified 8139 chip type 'RTL-8101'
eth0: link up, 100Mbps, full-duplex, lpa 0x41E1
eth0: no IPv6 routers present
eth0: link up, 100Mbps, full-duplex, lpa 0x41E1


3. Run dhcpcd to receive DNS-information and an IP-address

Code:

dhcpcd eth<NUMBER>


4. Use ifconfig to confirm this

Code:

ifconfig eth<number>


You should probably read The Gentoo Handbook Chapter 3. Configuring your Network.
