Error message on both Tivo boxes that TCP port 37 needs to be opened for my upstairs and downstairs Tivo boxes to communicate. How do I open TCP Port 37 on my Xfinity router?
i also need a solution to this
I'm having same issue. It started today. Called Comcast but they only did a modem reset.
Did you check Tivo support?
The first thing I checked was Tivo support - that is where I learned about the closed port.
