Thanks. A couple more things I'm interested to see and I can give you my lengthy spiel about how to fix this. 1) I'm looking at your 4-way Antronix splitter. You mentioned you have 4 total TV's (One TiVO and 3x Mini's). Do you also have a cable modem, or are you using a different provider for internet? If you do have a cable modem, I need to know how that plays into the setup since it would require another splitter somewhere. 2) Assuming Spectrum is giving you the minimum signal level required at the drop (0dBmv), you should be losing approximately 10dBmv by the time your Tuning Adapter is connected. Can you post photos of the following diagnostic screens from the Tuning Adapter? From the main diagnostic menu... Network and Tuning Statuses - Should be 2 pages of information. RF Statistics - Should be 2 pages of information.
