In the past, I have had strange behaviors like this as well.  Turned out 
to be a ARP race condition with my firewall with static IP assignments. 
  As soon as the second device would ARP, I would loose connectivity 
with the first device.

Check that you have no other device using the IP address that your D70 
is using.  Also, make sure that nothing else is competing with the 
Google Voice registration.
