Windows 7 Default Gateway problem

Question

I have a strange problem (or at least seems strange to me) the below are IP configurations for two laptops on my home network which consists of a main router 192.168.11.1 and a connected wireless router (i know this can cause problems but has always worked until I got the win7 machine) at 192.168.11.2 with DHCP disabled.

Laptop 1 - Win XP IP: Dynamically assigned by main router default gateway: 192.168.11.1 (main router)

This machine gets perfect connectivity.

Laptop 2 - Win7 IP: dynamically assigned by main router Default Gateway: 192.168.11.2 THIS IS THE PROBLEM... I cannot seem to get this machine to default to the main router for the gateway UNLESS I go to a static configuration which I would rather not do since I regularly go between my home and public networks.

Why is my Win7 machine not finding the main gateway the same way that the other laptop is?

I believe that the rest of my setup is fine as it has always worked and it works perfectly when set as static ip and gateway.

Please help!

Thanks

Solution

To disable IPV6 you must do so by registry or GPO. In you uncheck you only unbind from NIC, but OS still uses on network. On 7 and 2008 disabling IPV6 not recommended.

did you install any 3rd party connection manager with the network controller driver? and please post make and model.

What IP and mask is laptop 2 getting? And are you UTTERLY CERTAIN that DHCP is disabled on 192.168.11.2? And can you give us the pool that 192.168.11.1 is handing out?

DHCP is disabled on the WAP. Whats strange is that one laptop finds the correct gateway on its own.... yet the other has to be set static to do so.

How can you do it in the registry?
