And how, exactly, are you connected to the internet ?
Hi Paul
No , i have no router, and I'm connected via cable to the internet only by
cable modem
And yes, the yellow light is light-up when I plug-in the network cable.
I've tried both W2k and XP prof.
Maybe I havn't installed all the drivers.I looked on the Asus site and all
the drivers for W2k/Xp I have installed.
As far as I know I cann"t get an IP adres.
My other computer worked fine though, so it must be a problem with my new
machine.
Even I have tried to give my computer a static IP adres,(with the help of my
internet provider), I cann't get on the internet.
I love to hear from you to solve this !!

I am not an "IT guy" or a professional computer builder, just
a home user, so I make many mistakes.
As I understand it, the cable modem doesn't need an IP address
and bridges protocols. I think that means you won't be able to
ping it, unless it has some kind of maintenance interface on it.
In any case, we can use your computer to test itself.
Your computer has two Ethernet interfaces. The Nvidia interface is
100BT and the Marvell is 1000BT. A 1000BT interface supports MDI/MDIX,
which means you don't need a "null modem" style Ethernet cable
to connect it to other devices. The Marvell chip will reverse the
transmit and receive wires internally, if it doesn't find signals
where it expects them. This is why, for the following experiments,
you will not need any special cables - the ordinary Ethernet cable
will work for all trials.
You can actually do a self test of the computer onto itself.
This is the configuration I use:
Enable ICS
169.254.254.74 -----Nvidia----(Proc)----Marvell--- 192.168.0.1
(Address via DHCP) (Static address)
What I did on my computer, is pretend to connect the
Nvidia 100BT interface to the Internet. If you look in
the "Network and Dialup Connections", there should be two
icons for the 100BT and the 1000BT interfaces.
I selected the 100BT (Nvidia), right clicked on it, and
select "Properties". There will be a tab at the top of the
dialog box, labelled "Sharing". Enable ICS by ticking the box
in the Sharing dialog.
What enabling ICS does, is turn on both Ethernet interfaces at
the same time. It allows a second computer, to be connected
to the Marvell interface (the one shown as 192.168.0.1). If
a computer on the Marvell interface attempts to send packets
to the internet, the ICS software in the OS routes the packet
to the Nvidia interface, and there it will hopefully find the
Internet.
In my figure above, I show what happens if you enable ICS when
the computer is not connected to any network. The left hand
interface (the one where "sharing" is enabled) becomes the
Internet interface. DHCP is enabled on it, and the Nvidia
interface will send DHCP "Discover" packets to whatever device
is on the other end.
For example, with ICS enabled, you could do this -
Enable ICS
Cable_modem -----Nvidia----(Proc)----Marvell----- 192.168.0.1
XXX.XXX.XXX.XXX
When the cable_modem is connected, the Nvidia interface will
use DHCP, to get an IP address from your internet provider
(home.nl). That will define a numeric value for XXX.XXX.XXX.XXX .
If we use one Ethernet cable, and connect the two Ethernet
ports on the A7N8X-E together, with an ordinary Ethernet cable,
this is what happens:
Enable ICS
169.254.254.74 +--Nvidia----(Proc)----Marvell--+ 192.168.0.1

+-------------------------------+
First of all, the light emitting diodes (LEDs) on the two
Ethernet ports should light up. That means the two interfaces
have negotiated a rate to run the physical interface. The lights
should be indicating the wire is being run at 100BT.
The value 169.254.254.74 is a magic value. It is a value that
is used, if a DHCP server cannot be found. As far as I know, it
is considered a private address. The 192.168.0.1 value is
also magic. It is a private address and in this case it is
a static value. The value is assigned to the Marvell interface,
as a result of selecting "ICS" on the Nvidia interface. (You may
be able to change it, but I've never tried it.)
When the computer is connected to itself, open a MSDOS box and type:
ipconfig /all
This will print the IP address information for the two interfaces.
Verify the IP addresses being used are the same as the ones above.
Now, we can try a ping test from one Ethernet interface to the
other. In the DOS box type:
ping 169.254.254.74
where the numeric value I've used, is the address of the Internet
facing port (the Nvidia one, in this case). You should see
Reply from 169.254.254.74: bytes=32 time<10ms TTL=128
Reply from 169.254.254.74: bytes=32 time<10ms TTL=128
Reply from 169.254.254.74: bytes=32 time<10ms TTL=128
Reply from 169.254.254.74: bytes=32 time<10ms TTL=128
The LEDs on both Ethernet ports will flash when the packets are
sent.
If that works for you, it will have proved that packets can
be sent and received from both Ethernet ports. Now, you
can connect the Nvidia Ethernet port to the cable modem
Enable ICS
Cable_modem -----Nvidia----(Proc)----Marvell----- 192.168.0.1
XXX.XXX.XXX.XXX
In the DOS box, type
ipconfig /renew
What that should do, is cause the Nvidia interface to send
DHCP "discover" packets. It will stop using 169.254.254.74,
and should start using a real Internet address like
XXX.XXX.XXX.XXX . If you then do
ipconfig /all
you should now see a public address, assigned by home.nl,
applied to the Nvidia interface, while the Marvell will
continue to be 192.168.0.1 .
If the ipconfig /renew step says something like "cannot
reach DHCP server", then there is still something wrong.
About the only other thing I can think of, is there is
a problem with the MAC address. The MAC address is loaded
in the BIOS, and is originally set up at the factory.
The MAC address is supposed to be unique, and Asus will
assign a number to your motherboard that no other Ethernet
is using.
The MAC address can be erased by accident, while you are
flashing the BIOS. If you have flashed the BIOS, you could
have wiped out the MAC settings.
This thread discusses the MAC address issue. You may
need to flash the BIOS again, using the MAC values printed
on the labels on the motherboard as arguments to the
flash command.

So, try some tests and tell me what happens, and what
you see.
