i have an RV042 dual wan that is connected to a dsl line and a cable modem line. i run several apps that stream data and use several web pages at a time. i am having an intermittent problem where my programs and webpages will not be able to connect to what they were connected to. for example AIM gets disconnected and will not reconnect or i won't be able to access a web page. I have two desktops connected and can be running a continuous ping to say "google.com" successfully yet lose connections in individual webpages and programs. (Another ex: i cannot access google.com in web browser on one machine, but can on the other machine - while ping google.com is working on both). i'm wondering if it is because the a program establishes a connection through one provider and cannot switch easily to the other... say if my dsl went down and existing connections through the phone company cannot reset through the cable company. An example - i unplugged my cable modem and all of programs and web pages lose connection and cannot reconnect, even though the dsl line is still up. For some reason, I thought the load balancing feature in this router could handle all of this. Can anyone tell me if I am wrong in thinking this?
