Silver lets see if we cant get this worked out.. first of all im going to need some details about your hardware. I want name and model numbers of anything between the WinMX computer and the Internet coming out of the walls... lol
I also want to know what if anything you can think of changed when this all stopped working.. updates, new devices.. firmware updates, anything you can think of please.
Can you also please confirm you are using the latest WinMX Group Patch. It should say Patch Operational in the update bar under your WinMX vnumber and just above the Networks button.
Id also like to know what firewalls and antivirus your using now, any protection software you have installed. Get me this info and well see what we can do.
Can you tell me why you have the Vonage also if you have a Wireless Linksys? Im not trying to be daft or sarcastic, just need to know why you are set up with a modem and two routers.
