Hi,

Here are suggestion to resolve a common problem with Windows 7 connectivity concerning IPv6

-          Check for compatibility

-          Update driver network adapter

-          Go to Device Manager

-          View Hidden Devices and click on + icon to Expand Network Adapter

From here, you can either:

-          Disable Tunnel Adapters (6 to 4 ISATAP) – with adjacent IPv6 host

-          If you choose to depend on tunnel broker

-          Check and configure

OR

-          Check your if your anti-virus firewall NDIS is filtering the port

-          Check with your anti-virus support desk for operation on opening the port

A.)   Open Device manager

B.)   Click View tab at the top and click on Show hidden devices.

C.)   Now Expand Network Adapters by clicking on the (Arrow) icon beside network adapters. (Now you will see lot of icons down in the list)

D.)   Check in that icons if there is any ANTI VIRUS FIREWALL NDIS is there and is FILTERING THE PORT.

Example: AVG Firewall NDIS Filter Miniport

E.)   If there is ANTI VIRUS FIREWALL NDIS icon FILTERING the port, then kindly please follow these steps;
