no network access

Hello,
At first please forgive me for my bad english...
I have very common problem (as i see on the forums) but I still haven't found the solution.. I have 2 computers ... the old one (with win XP installed) and brand new one (with win 7 x64 ultimate inastalled). The problem is ... on the old computer internet works fine, but on the new one i Just can't get it work. It allways says "No network access". I have no router ... computer is wired directly to my cable modem. I tried nearly everything ... but still no succses Network card (realtek ) is integrated to my motherboard and have installed the latest driver. Here are some snapshots...
I can snapshot&attach any other window, just tell me wich one.

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 Windows 7 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 Windows 7 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.

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 Windows 7 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 Windows 7.

Yes I did get a cd, but there is only driver for usb connection. No setup, or anything usefull. The cable guy said that the modem doesn't need extra driver installed. It seems like it have an avtoupdate... I don't really know.

Yas, I set up menually my static ip, becouse dhcp didn't work even on xp... I did the same thing on the Windows 7, but no succes.

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.
