Would the ISP interfere with the Netburner but not the camera ? The camera is, by far, using the most bandwidth.

Does the camera get accessed via a standard web page, or is it a java applet or program? Also, I'm not sure if a device can be both a DMZ and port forwarded. All the routers I am familiar with for DMZ will forward all traffic. I could not have a single IP address for both DMZ and port forwarding.

How about rebuilding your app and switching the camera and netburner port numbers. See if that makes a difference.

I don't see how swapping ports would make a difference. Why would one port number be intermittant and not another. Why would it work at some locations/times but not others ?

The camera does use a Java applet.

Are there any web sites that reliably use a Netburner on a home cable modem ?

What kind of router do you have at home? Most of the time home routers have some firewalls which filter out 'suspicious' traffic. The firewall logic may understand the webcam traffic, but might think the web traffic is suspect. It seems unlikely, but worth a try to disable the firewall on the router temporarily to see if it alleviates the problem.

When I have a problem like you are having I will usually build a subset of the app that is simpler
(like not using java applet) and work my way back up to find what is failing. I have had no problem using DSL/home/linksys/port forward with netburner serving packets. I would try sockets alone, then web server with HTML, then java applet in that order. One of those will show the intermittent problem and the others below it shouldn't.

I have disabled the firewall. In addition, the Netburner is in a DMZ that is outside the firewall.

It is a Netgear WGR614 54Mbps router.

The Java Applet is run by the camera, not the Netburner. The camera HTML is in its own Iframe and does not effect the Netburner. The main web page is hosted on my commercial hosting. That commercial monthly web server has all the high bandwidth stuff like the pictures for the buttons. The Netburner page runs in an Iframe and all the Netburner has to deliver is perhaps 150 bytes of HTML. The Netburner HTML is above.

Just for grins I bought a D-link DGL-4100 router that is intended for gaming. It will be here in a few days and I will see if it helps.

Got it, Netburner is only serving HTML.
Have you tried netburner in its own page (independent of all of the other iframes) accessed from outside running something like your application (or your application on its own page) to see if browser is getting involved in the intermittent activity because of layout/HTML/etc. problems?

Yes - in some cases just typing in the Netburner numerical IP and just putting the controls in the middle of the page seems to help somewhat. It is still not at all reliable however. I had someone try it remotely and they said:

"Browsing to the same page in I.E. 8, after loading a java add-on, results in a picture of the train layout in one pane and a 404 error where the controls should be. The 404 error says the site is accessible. The page is faulty.

If I access the same page via chrome, it works but is a bit balky to start and complains of an expired certificate. Allow it to ignore that problem and you can see and control the train. No sound. Not sure there should be."

Apparently it works, at least for that person, in Chrome. IE 8 produces the 404 error like it does about half the time at the internet cafe.
