Did you get a chance to try those steps?

Since your router LAN IP is not the same as the V9 there shouldn't be an issue with IP address conflicts.

Do you know why you're using subnet mask of 255.255.254.0 instead of 255.255.255.0 ?
Do you know the difference between a MAC address and an IP address?  Notation difference?

Were you able to reconfigure your V9?
