Question : Vonage and D-Link issues...

I am running DSL (cable isn't available), a brand new D-Link DIR-655 Router and a Motorola VT1000 for Vonage.  Before installing the D-Link Router, everything was great.  But, I needed better signal strength, so I upgraded to the DIR-655.  Since then, I cannot talk on the phone via Vonage without losing the internet and/or the phone call.  I have switched the configuration around as follows...

DSL Router - Vonage - D-Link
DSL Router - D-Link - Vonage

Results were similar in both situations as that I lost the internet.  I didn't lose the phone call with scenario 1.

I have a static IP address and configured both devices correctly depending on the scenario above.

I have opened up the firewall.  No luck.
I have set Port Forwarding.  No luck.

Any ideas?  Thanks.

So, looks like you got sick device...
Besides that, are we talking about internet connection over wireless or wire?
This static address in the LAN or assigned to your WAN by ISP?
DIR-655 has 1Gb ethernet ports. Is it possible to set them to 100/full? How long is your cable? What kind of network adaptor in your hosts in the LAN?
