Brother it does not matter what ip-address you put and by the way there can be thousands of reasons.....

Let me go through with you some....

1. IP-address not in the same network.

2. You inserted the wrong subnet mask.

3. You defined the wrong gateway ip.

4. your network card is not correctly configured.

5. Diver not supported by your OS.

6. Network card firmware upgrade for your new OS.

and so on .... so on... so on........

Good luck.... If it was Linux i could have helped you better than this one.......

I simply hate windows..........
