How to tell Tivo to use the internet?

[Hathar]

I have a Turbonet card in my TiVo Series 1. I've had it in there for years. It's now suddenly failing to connect. I've done various things to make it work, and now I managed to clear out the dialing options. I need to tell it to use the internet.

I remember that it was a special code you do with the remote, but I can't remember what that code is.

Can someone please help me?

,#401 as the "dial prefix" in the dialing options.
