I moved, now my on board Ethernet, or PCI network card is not functioning
 

Last month, I left Texas in order to live in New York State.
I shipped my PC UPS, it was packed well for shipping (in original
packing material). All is fine,except I can no longer connect to the Net.
When I boot, I get a message that the wired connection is established;
when I try to ping Google or Yahoo, there is no connection.

I want to upgrade, I'm running an older version of Ubuntu,
but it will be no better without a working Internet connection.

I an running an AMD 64x2 with a gig of RAM, the BIOS is Phoenix.

There is no physical damage to the box, but could this be a setting in the BIOS?

When I moved, I simply disconnected the Ethernet cable and shipped.

I tried to enable the PCI network card in BIOS, after disabling
the on-board eth0. Re-enabled the on-board, and still no connection.
The Cable Modem does show an Ethernet connection, as well activity
on both the modem and LAN port.

Thanks for the response....

Can you do the following and post the results:

Do you have your IP address hard coded or are you using DHCP? If hard coded, it may be wrong now since you moved to a new location. Just a thought as it seems that the hardware is working from your description.

Static or DHCP?
 

..it is DHCP, as it was in Texas. I look at the Network settings to confirm this.

Let me throw out a few questions.

Is this a new cable modem or one you brought from Texas?
Have you verified with the ISP that they have the correct MAC and if they can see the MODEM?
You might need to get the cable company to verify the signal strength at the MODEM is sufficient.
Are you directly connected to the MODEM or are you using a router?
Is this the only computer connected?
I assume that an IP address is not being assigned via DHCP.

The modem is new, it works perfectly with my laptop running 9.04.

I ran isconfig route -n, this is the output:

I ran DHClient and received ..."No working leases in persistent
database - sleeping."

I've reset the mobo to default settings, but this still is an issue.

Only a 2-year-old box, hope it is not the mobo.....

Are you using a router? Or connecting the computers one at a time. The typical home cable service only provides one IP address based on the MAC.

No, when I switch from the Desktop to the Laptop; I switch the
Ethernet cables.

The MODEM stores the network adapter's MAC in its volatile memory which is preventing your laptop from connecting and acquiring an IP address. You can configure the laptop with the same MAC as your desktop using the ifconfig command and then run dhclient. As a more permanent method add a hwaddress line to the /etc/network/interfaces file:

Of course you can cycle power on the MODEM which will erase the memory when you switch computers too.

Whoa! This worked....
 

When I lived in Texas, I had the same ISP (Time Warner), but I could
switch PCs on the fly. There was a different Cable Modem there.

When I first connected in my current setup, the Laptop was the
Internet device used. In the temp housing I had when I first
moved to NY, there was a Wireless network setup off the
Roadrunner, but it will cost me less to edit my
/etc/network/interfaces file

Thanks sooo much for the input michealk, and the other contributors....
