Router connection issues

[toli]

Any possible solutions or even a direct cause of the problem would be helpful:

My parents' computer cannot identify their router. They are using a wired connection, and I have tried switching both the cable and ports. The port light is green and solid however. My laptop can connect fine and both are running Vista Home premium 32 bit.

The computer can ping itself and I have tried to use ipconfig release and renew but nothing has worked so far.

Here is the ipconfig for the working computer:

Windows IP Configuration


Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . : gateway.2wire.net
IPv4 Address. . . . . . . . . . . : 192.168.1.103
Subnet Mask . . . . . . . . . . . : 255.255.255.0

Link-local IPv6 Address . . . . . : fe80::5efe:192.168.1.103%15
Default Gateway . . . . . . . . . :





and now for the broken one:

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
IPv4 Address. . . . . . . . . . . : 169.254.136.46
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :

Tunnel adapter Local Area Connection* 6:

Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :

Tunnel adapter Local Area Connection* 7:

Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :


I have tried setting static ip addresses but it does not work. Also the network says Unidentified network (public network)

I will be the first to admit my lack of computer know-how but obviously something is wrong here.

Thanks

Windows Vista
Open up a command prompt (Start > All Programs >Accessories > alternate click on Command Prompt > select "Run as Administrator"
Type the bolded commands into the command prompt window:

Reset WINSOCK entries: netsh winsock reset catalog
Reset IPv4 TCP/IP: netsh int ipv4 reset reset.log
Reset IPv6 TCP/IP stack: netsh int ipv6 reset reset.log

When finished reboot

I tried this but it was unsuccessful. However there was an error when trying to reset the ipv4:

[b]Reseting Echo Request, failed.
Access is denied.

Reseting Interface, OK!
A reboot is required to complete this action.

Did you open the command prompt as administrator?

[toli]

yes the other two commands worked fine

Reinstall your network drivers
