So you think ST585v6 modem is not the problem causing my connection FireWalled? This model is utilizing UPnP. I even tried this: Network Connections/Advance/Optional Networking Components/Networking Services/enabled or checked UPnP User Interface.
Still my LW is FireWalled, though I have a Turbo-Charge Connection.

I am still working with the suggestion of Lord of the Ring. My installed anti-virus is Kaspersky6.0. I tried checking the setting to include LW in the exceptions but I can't find it. The settings is only limited to allow which port has to be scanned for virus. I tried adding and removing LW with its port to no success. I also tried to disconnect (exit) my anti-virus with no positive result.
