Ok, hopefullt this is what you're looking for:

My router says it's a Haltron Tech model # BRG-35202
My ISP is an off the wall company called TV Max.

I don't beleive I have another Firewall because when I go into my control panel, all I see is a "Windows firewall" and if there is another firewall running, I have no idea where to find that info. Under my firewall options, it's set up to allow LW to get through, so I don't understand why all of the sudden it's not working.
