RR cable - Amp / Splitter - 1. TV; 2. cable modem

cable modem - Vonage adapter - PC

if add wireless router, add between cable modem & Vonage adapter. (If my Vonage adapter is also a router, you can change this around but otherwise this is the setup.)

For troubleshooting, can plug in the wan/internet port of router to PC directly without Vonage adapter.

So,
  Regular setup:  RR cable - Splitter - cable modem - wireless router - Vonage adapter - PC. 
  Troubleshooting:
     (1) testing Vonage adapter: RR cable - Splitter - cable modem - wireless router - PC
     (2) testing incoming TV signal: RR cable - M/M connector (location: back of my desktop home computer) - TV
     (3) testing incoming Internet signal: RR cable - cable modem - PC

Other setups/suggestions:

(1) You are FAR better off to hook it up like this.... 
     Internet -- Vonage Box -- Wireless router
The reason being that the Vonage box requires a stable constant stream of data to work properly. Also the Vonage box will when required slow your wireless router down to make certain the phone is not disrupted.  I tried it hooked up the other way and had problem after problem with it... however once I hooked the Vonage box directly up to the internet no problems at all.  [ 03-06-2009]   myComment:  this is an old fashion way to setup for old devices.

(2) While in my experience setting up a wireless router to work with a Vonage router (not non-router adapter like mine!?) is more complicated than described above, the need to have the Vonage router first in series off of the Modem with the wireless router to be next in the series after the Vonage router, is decade old technology. First, in my opinion, compared to what was available at least 5 years ago, Vonage VOIP enabled routers suck as routers. As for priority of voice data to maintain a minimum quality in VOIP communications, routers such as the D-Link DIR-855 Xtreme N Duo Media Router (and less expensive models) are specifically designed for prioritizing data handling for uses such as VOIP (Vonage), streaming HD video, etc. You also get an n 300Mbps wireless speed router with Gigabit hard-wired capabilities. I am adding this comment so someone finding this thread does not read it and be misled about what is state-of-the-art in July 2010. Now if you'll please excuse me, I am needed elsewhere.

There is another problem you may have if you buy a new Wi-Fi router/access point and put it in the line between your cable modem and the Vonage adapter.

Many ISP's (phone and cable companies providing internet service) now will only talk to ONE device at your house. Their service agreement may even say that you may only run ONE computer on the line. This is largely an attempt to get you to buy their N router. If you do that, you won't have a problem, they'll tell you what to do.

If you buy another, you may find that nothing works. The reason is that their cable modem is set to talk to ONLY your personal computer's card using it's MAC address (the serial number of the network card in your computer).

You can "fool" them and have it talk to an N type router by buying one that has the "MAC address clone" feature. Linksys and others sell such routers. They have instructions on how to set up "MAC cloning". Written largely in geek-speak.

Here's a relative friendly discussion of how to do it. If you need it. The symptom will be that when you plug in the new modem, you can attach to it wireless but will have no internet connection.

An easier way is to get a geek friend to set it up. JUST MAKE SURE YOU HAVE A ROUTER WITH "MAC address cloning". Lots of them around.

call Vonage to upgrade firmware.  Note 1: my adapter is  VDV21-VD.  No need to get a newer model (the VDV22-VD) since it may give no help.  Note 2: the setup of this guy with problem of "Audio issues - drops in and out" is Cable modem -> Vonage box -> wireless router.  .  So cable modem - wireless router - Vonage adapter is a better setup.     src
