A cousin told me my ethernet adapter or network board will depend on my motherboard. My computer upgrade document says the motherboard is gigabyteGBabyte video onboard. I heard gigabyte'sGBabyte's network adapters are GigabitGBabit or Realtek.

In CentOS, System -> Administration -> Network -> New -> Ethernet, first, only "Other Network Board" was listed, so I selected it and clicked Next, then there wasn't GigabitGBabit, but there was Realtek, so I selected Realtek.

So I tried Realtek with dhcpdhcp, but eth0eth0 wasn't found.

we didn't upgrade that time, the motherboard is Asus. /sbin/lspci -v/sbin/lspci -v shows that the Ethernet controller is Atheros L2, subsystem is Asustek.

http://www.linuxquestions.org/questions/Linux-networking-3/unable-to-activate-eth0-attansic-l2-on-centos-5-1-a-619969/

A cousin told me my ethernet adapter or network board will depend on my motherboard. My computer upgrade document says the motherboard is gigabyte video onboard. I heard gigabyte's network adapters are Gigabit or Realtek.

In CentOS, System -> Administration -> Network -> New -> Ethernet, first, only "Other Network Board" was listed, so I selected it and clicked Next, then there wasn't Gigabit, but there was Realtek, so I selected Realtek.

So I tried Realtek with dhcp, but eth0 wasn't found.

we didn't upgrade that time, the motherboard is Asus. /sbin/lspci -v shows that the Ethernet controller is Atheros L2, subsystem is Asustek.
