Internet connection is lost after resuming from hibernate
SYMPTOMS
When you wake a Windows Vista-based computer from sleep, the
default gateway setting is lost.
When you run the ipconfig /all command to view
the IP configuration, you can't see the
default gateway setting.
This problem occurs if the following conditions are true:
• The computer is configured as a Dynamic Host Configuration
Protocol (DHCP) client, and the computer is
connected to a DHCP server.
• The DHCP server configures a scope together with options 3 and
249.
• The computer is included in this scope.
CAUSE
After you wake the computer from sleep, the DHCP Client service
(Dhcpcsvc.dll) is responsible for informing the IP stack about
the routing information. The routing information is stored in
the network store interface. This problem occurs when the
network store interface already has the routing information that
the DHCP Client service wants to store. When the storage
operation fails, all routing information in NSI is lost.
Therefore, the computer loses all the routing information. This
includes the default gateway.
