I am using the following skeleton program, DC 9.21, and Windows Vista
Home BASIC in my test:
- Run the following program under DC 9.21
- Turn on Vista PC
- Connect a cross over cable between rabbit and Vista PC
- Rabbit first try DHCP and fall back to 192.168.0.123
but VistaPC will come up in IPv6! and we can’t talk to rabbit
Once Rabbit falls back to 192.168.0.123, if we disable/enable the
network controller on Vista PC, it will come up with IPv4, and everything will
begin to play
I also tried embedded ethernet controller from Lantronix called XPORT,
and it didn’t cause Vista to switch to IPv6
If I uses a XP PC instead of Vista PC, everything works
If I connect the VistaPC and Rabbit to a DHCP based network, Vista PC
will come up as IPv4 and everything will play
Disabling “IPv6 on VistaPC” doesn’t solve the problem: VistaPC simply come up with no network in our test
If rabbit is forced to come up with static IP (without DHCP at all), VistaPC will come up in IPv4
I am convinced rabbit’s DHCP section is having a conflict with Vista
Any advise?
Thanks!
