Realtek RTL8201 NOT FOUND

**ruckstande** · August 7th, 2008

I just installed Ubuntu 8.04 on my computer. I have a new Biostar NF4 4X-A7 mobo with a Realtek RTL8201 built in ethernet adapter. I didn't have this problem with my defunct Asus board and this is really frustrating. I can't really find anything about this adapter not being found. Please help.

Okay this is really disheartening. Am I correct in assuming the NVIDIA nForce4 4x chipset isn't compatible with Ubuntu?

Anyone know anything about this? I was really hoping to be able to start this project soon but I've hit a big roadblock.

I have a Jensen pcmcia wireless adapter, which has a realtek chip inside (RTL8180L). It works fine under 6.06 and 6.10 and Vector, but not under 7.04 and up.
lspci returns the following:

How do I make this pcmcia wifi card work under 7.04?

Any suggestion is appreciated!

b.t.w. my pc is an old dell laptop (latitude cpx 500 with 384 MB ram)

"Not Found" is a bit vague, but let me feel around in the dark and see what I can do. I think this is supposed to use the module forcedeth. Please open a terminal and do:

Code:

sudo modprobe forcedeth
sudo lshw -C network

Did your Realtek get a logical name, ideally eth0? If so, please do:

Code:

sudo dhclient eth0

Did you get an IP address?

If none of this works, please let us see:

Code:

dmesg | grep -i eth

Thanks.

Go into the BIOS and turn PnP aware OS to "off"

I'll try that first thing. No nothing says eth0. Nothing appears at all. When I say "No device Found" when I click on the networking icon next to the speaker it says "No Device Found".

Okay, I installed a netgear card just to get this box online. That is identified as eth0. The other device is eth1. Here is the result of sudo lshw -C network:

One other thing, Ubuntu now sees the card but not as a Realtek as described in the motherboard manual but as an Nvidia Corp CK804 Ethernet adapter.

I ran this command as well: ifconfig -a
