Your Computer Loses IEEE 1394 Network Connectivity When You Resume from Suspend or Hibernate

If you bridge an Institute of Electrical and Electronic Engineers (IEEE) 1394 network adapter with another network adapter, suspend or hibernate the computer, and then resume the computer, network connectivity on the IEEE 1394 adapter may not work for approximately 10 minutes.

This problem occurs because the Arp1394.sys driver flushes its cache during a standby and resume operation, but the bridge miniport driver does not.

To work around this problem, use either of the following methods:

• Deactivate and then reactivate the bridge miniport connection in the Network Connection tool.
• Clear the Address Resolution Protocol (ARP) cache by typing the following command at a command prompt:
  arp -d ip_address

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
