You are correct on the router port connections. The MagicJack was powered down, pulled from wallplug, for 30sec to reset it. There are
2 phones connected. Cap-Tel and AT&T. Both work. I moved the MagicJack to #4 on the router. I made 3 calls and
the connection was acceptable using the AT&T phone. There are NO extension cables to MagicJack, Computer, Router
or Modem.
I just received a message from TP-LINK. They said Port Forwarding would do nothing in this case.
