no network access

Welcome to Seven Forums! I'm sure we can get you fixed up.

It's always advisable to have a separate wired router in between the PC and the cable or DSL modem. It's just safer and also allows considerably more flexibility in conning other devices (like more computers). If you can swing it, that's by far the best way to go.

But since you don't have one at the moment, we'll work with that.

Is it your intent to have both connected at the same time or are you replacing the XP box with the new W7 machine?

If you still have the XP box, hook it back up and get it running on the internet. Once you have that done, go to the start menu and click "run". Enter "cmd" and press enter which will open a command line window.

From the command line, type: "ipconfig /all" (no quotes) and press enter. If you can, take screen shot and post it here. What we're looking for is how the ethernet connection is configured. Rather than doing a 20 questions it just may be easier to see a picture.

Normally PC's are set to get an IP address automatically from a router. In addition, the router may do a login to the network using something called PPPoE. Sometimes the modem does it and sometimes the router does it. When you connect a PC directly to the modem, it's possible the PC could be configured to do the login.

If your XP box is configured for PPPoE, that could be the problem. PPPoE isn't a default for network connections so the new W7 box wouldn't be able to login, and thus no internet connection.

This is all a guess at this point until we see how the XP box is configured.

Is it your intent to have both connected at the same time or are you replacing the XP box with the new W7 machine?

I'm replacing the xp box with the new one (don't have the place really for bolth of them)

Here is screenshot from xp ipconfig. Now I'll switch the comps, and screenshot the same window ... so you could compere

I'm back... here are screenshoots from win7

When you installed your cable modem did you get a setup CD by some chance?

The reason I ask is you have the same static IP address on both machines. Did you actually set that address yourself as part of a configuration process?

It's starting to look like you may have PPPoE on the XP box but not on the W7 machine. When you look at Control Panel => Network Connections on the XP box, is there an entry for a "Broadband Connection"? That would be a dead giveaway that you need to create PPPoE connection in W7.

Here's something to try:

Disconnect the PC from the cable modem.

Power OFF the cable modem. Unplug it from the power supply. Wait about two minutes and plug it back in.

I just remembered that a friend of mine had this same issue. The cable modem "learns" the MAC address of PC that's connected to it. In order to get it to "re-learn" the new PC, you have to reset it by doing a power cycle. In his case we also had to remove a little backup battery.

Does the modem have a backup battery? What make and model is it?
