Can't connect to Internet through Ethernet cable. USB cable connects OK

[Don_G]

I am using an XP Computer with a DSL line through a SpeedStream modem that
allows me to connect either through the USB port or the ethernet port.

I can connect through the USB port, but when I plug in the ethernet cable, I
can't get a connection even though the modem's DSL and ethernet lights come
on. In the command prompt, I can't even ping www.yahoo.com.

I went into Control Panel - Network Connections to disable the USB network
connection and enable the Ethernet network connection.

I brought up a command prompt and typed:
ipconfig /flushdns
ipconfig /release
ipconfig /renew.
ipconfig /all does not show a valid IP address with the ethernet connection.

Nothing works to get my Ethernet connection working. It did work a few
months ago, but not now. Is this the fault of my internet service provider?

Can anyone give me some hints for troubleshooting this problem?

Things to try:

1. Go to Device Manager and make sure the network adapter (NIC) is not
disabled. If it has a red "x" next to it, right-click on it and Enable it.

Control Panel>System>Hardware>Device Manager>expand Network Devices to
find your NIC.

2. If the NIC is enabled, go to Control Panel>Network Connections.
Right-click on the Local Area Connection that represents your NIC and
left-click on Properties. A Properties box will appear. Double-click on
TCP/IP to get its Properties. Set DHCP and DNS to automatic.

3. Try a different ethernet cable.

4. You didn't give us any information about your computer. If this is a
desktop computer and the NIC is on the motherboard, go into the BIOS and
make sure the NIC is enabled.

4. Try a different NIC (last resort - please try the other things first).

Report back with results. If nothing above worked, please include some
information about your computer, too.

Thanks to Malke. I tried all the recommendations and nothing helped. I
have a desktop Pentuim 4 CPU running at 3GHz with Windows XP Home Edition
"Version 2002 Service Pack 2." I called my ISP's help desk and they put in
a repair ticket for another DSL modem. I hope that fixes it.

Regards,
Don

I hope so, too. If it doesn't, we can go further with this but it's
smart to try a different modem.

There is two other tests that "Don_G" could do. If you have a friend
with a laptop that have a Ethernet port, get a cross-over cable and
test connect the two PCs together. Also, while the friend's laptop is
close to the other PC, try it with the DSL modem. This will/should
"narrow" down where the problem is.

Thanks to all who responded. A Laptop PC didn't work either. My ISP
replaced the modem and the Ethernet connection started working properly.
