Nothing has changed. My TiVO was tweaked a year ago. It last connected on Wednesday. NBN is working fine. Does anyone have any ideas on what I can do to get my TiVo connecting again? DNS Resolution has succeeded. But I note that Port Configuration has failed. How do I fix this? I am 67 yo female and not at all into "techo" things. I have tried restarting the machine but it still does not connect to my network.
