I have a Series 4 that WILL NOT connect to my Linksys E2000 Router when I have the following settings. Under Wireless - Wireless MAC Filter. When it is Enabled - Permit PC Listed Below. And I have the MAC Address entered into the Table; I can't get connected to the "N" Adapter on the Tivo. If I Disable the Wireless MAC Filter, Then the Tivo will connect. It makes NO since, since the MAC Address is "CORRECT" in the Table!!! Any thoughts, out their?
