Advertisements A fixed IP may not help but, as the saying goes, "It couldn't hoit." and it eliminates one source of possible problems. As far as what address to use, generally a local network will have addresses in the range "192.168.n.n", so I start with 192.168.1.101 and go from there. You do need to find out what the IP address of your router is. If you don't know, don't have the documentation and it isn't written on the actual router, post the make and model of the router. Also open up a command prompt on your computer and enter the command "ipconfig". It should show up as "Default Gateway". You set the IP address for the TiVo using the "Phone & Network" setting. Here is what TiVo has to say about it. I use "184.108.40.206" and "220.127.116.11" for DNS servers. They are the Google public DNS servers.
