Windows 7: LAN does not have a valid IP configuration

04 May 2010   #1

Solved - LAN does not have a valid IP configuration

I am not able to connect to the internet using my Windows 7 computer.

It is connected to internet via LAN. So, the router is not directly connected to this PC. The owner of my router is my neighbor.

Internet works for him very well using the same connection. Only my LAN connectivity does not work.

Here is the IPCONFIG info. Any one help me, what can i do to resolve this issue for my client PC.

Did you blank out the default gateway, or is it blank already?

Can you connect to the network at all?

You have no default gateway showing in your ipconfig so file sharing can't work the way you have it. I'm not sure why you aren't picking up your neighbors default gateway.

You can find out and then type in which ever default gateway your neighbor is using but you will need a special program in order to share your wireless connection with your other machines.

If you are trying to share the wireless connection from your neighbor through your machine there is a free program for that called connectify.

Its not Wireless. Its Wired LAN. I didnt not remove the gateway

and the Gateway and IP are automatic. Why would i need to assign?

It was working so far with the same settings.

* I have reset the Winsock
* Tried disabling Ipv6
* Even system restore
* Unplugged and re-connected the LAN cable in both ends.

None of the above worked. Do I have to upgrade Windows installation? or re-install?

Additional Info:

I connected the same LAN cable to my Laptop and the internet worked fine.

Sorry I just assumed because you were borrowing his connection that you didn't have an eithernet cable running from his house to your own.

I also assumed that when you said this> It is connected to internet via LAN. So, the router is not directly connected to this PC. The owner of my router is my neighbor.

Usually when someone is borrowing a connection from their neighbor it's wireless. I'm not sure how you can pick up the connection if you aren't connected to his router?

In any event if you are using a cable you can just have him reset the router per manufacture instructions for his router and you should be able to pick up the default gateway.

# Oops am sorry I wasn't clear. Yeah.. I connect to the router via Cable.

# Am the only admin for this connection even if he is owning. How will I reset the router in his Laptop? And it works for him and another computer. Should I really reset the router?

# Guess its a very old router. Hard to get the manual. Any alternative solution? like re-install or upgrade my Windows copy?

This could be a faulty cable - have you tried another and of the correct type. If it's a cross over type and the router is old then it may not be able to auto 'adapt' for this and a standard wired cable will be needed....

@ Hobbit,

The same cable and connection works with my Laptop. So, I guess the cable is still good

Will over-write windows and see !!
