I am so sorry for the late reply. Today only I could test other cable.
The problem isn't from the cable It seems that the computer send data to the modem but the modem does not respond at all.

As I told you before, the problem could be from the Windows tcp/ip stack. But you tried in another PC also... so my conclusion is that the ethernet port on the modem is probably broken. Anyway try to recover the tcp/ip stack with the utlity winsockxpfix:
http://www.webattack.com/get/winsockxpfix.html
reboot the pc and setup the tcp/ip parameters as follows:

IP address 192.168.1.2
Subnet mask 255.255.255.0
Default gateway 192.168.1.1

Close any firewall (Windows XP firewall included) and antivirus and try to access the web config page at

http://192.168.1.1

Try also to remove the USB modem driver, it could interfere in some way...

Thank you for you help.
I tried the winsockxpfix with no benefit.
I tried to update the modem with other modem firmware and the result was all the leds are off exept the Power led.

Thank you again for you effort.
I read about serial port inside the modem and I saw the pins (5 pins). how to connect to it?
Also, I read about recovery tools and adams2app what all these tools about?

Best Regards

The recovery tool and adam2app are both ADAM2 based recovery utilities. They work via ethernet port only. The serial interface console is a mere ADAM2 monitor and it is unuseful in order to recover the firmware. There's no simple mode to recover the firmware if ADAM2 ftp server does not respond or ADAM2 doesn't exist anymore on the flash rom. If ADAM2 is dead the only effective way to revive the modem is to recover ADAM2 via JTAG interface and reflash the firmware via ethernet port. However, if the ethernet port is dead, you will not be able to recover the firmware. Anyway here:
