PC cannot connect to router

Acer / ASPIRE

Specs: Windows Vista
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
Default Gateway . . . . . . . . . : 192.168.1.254

Tunnel adapter Local Area Connection* 6:

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

Tunnel adapter Local Area Connection* 7:

Connection-specific DNS Suffix . :
IPv6 Address. . . . . . . . . . . : 2001:0:4137:9e50:2892:3464:3f57:fe98
Link-local IPv6 Address . . . . . : fe80::2892:3464:3f57:fe98%10
Default Gateway . . . . . . . . . : ::

Tunnel adapter Local Area Connection* 9:

Connection-specific DNS Suffix . : gateway.2wire.net
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

hmmmm.......there's definately something going on with their laptop.

About the only thing I can think of that you haven't tried is uninstalling, then reinstalling the TCP/IP protocol stack.

Give that a try and see if that doesn't fix the issue. I've run into situations where something in the stack gets corrupted and it stops working properly and this fixed that particular issue.

If that doesn't work, maybe try uninstalling the entire NIC and then reinstalling it and see if that doesn't fix the issue.

I appreciate the tips, but would you happen to have a step by step guide I could reference for those solutions?

Thank you
