click up a CMD termainal,
ipconfig /release /all
Remove power from cable modem for 15 seconds by your clock.
remove your ethernet and usb cable from modem.
Power up cable modem, wait for leds to return to normal.
Plug in ethernet cable.

ipconfig /renew

try doing a
ping http://192.168.100.1

That is a web page server in Motorola SB4xx or SB5xx cable modem.
if works, you can talk at the cable modem on ethernet.

I'm having what I think is the same problem. I've repeatedly done al
of the renew, ping, and power off/on routines that you mentioned an
many more. I'm now to the point where I can get a connection, but i
doesn't last for long, and will "flicker" off and on. The LAN statu
still shows "Connected," but I can't always pull up a web page. I'v
tried multiple ethernet ports (one attached to the motherboard and on
on a PCI card), multiple ethernet cables, multiple modems, an
with/without a router. I do not have the Windows firewall turned on
but have tried both with/without my Norton firewall. Since the proble
continues regardless of the hardware, I'm convinced that it ha
something to do with software/settings on my computer, but I have n
idea where to start. I thought it might be the firewall settings, bu
it continues even when that is turned off. Actually, if I remembe
correctly, I get a different message when the router is taken out o
the mix - it says that there is "Limited or no connectivity" and i
cannot find my IP address. I went to the web page that you mentione
and found the following log entries - do these give any indication o
what might be going on? (My current hardware is a Motorola SB510
cable modem and a Linksys BEFSX41 broadband firewall router.)

I haven't checked again recently, but these problems did not occur wit
my USB port. However, I want to use the hardware firewall, and this i
only possible with an ethernet connection. Any help with this would b
appreciated

If you can ping 66.94.234.13, you are connected to the internet and
doing 99% good. If that ping works and ping yahoo.com fails, your DNS
servers are AFU.

Since I do not do windows, I cannot help you.

Next chance you get, download a knoppix iso and burn to cd.
boot cd set dhcp on ethernet and use a public dns server.

If that stays on solid, you know it is software.

Always helps to get a second opinion to rule out hardware.

Anytime you change the hardware connected to the cable modem, you have to
power reset the cable modem at least 15 seconds just to talk to the modem.

Those are normal on a booted cable modem.
You need to show your up/down stream signal values to rule cable modem
connectivity.

You have to get to known state to trouble shoot your problem.
Get the knoppix to rule out hardware and software.


Well if USB works SOLID, that indicates the cable modem connection is
working.

Does not rule out ethernet port side of modem.

I hear that. Viruses are trying to disable those.

Buy or get a friend to burn a knoppix cd to help you rule out hardware
problems.
