OK, I have a Series 3 and a Series 2 on a wired network on 192.168.1. The S3 has a static IP address of 192.168.1.10. the S2 on .11. I can ping them from other machines on the network. There's a Lynksys router at 192.168.1.1 connected to a Cablevision cable modem. Every other PC on the network can connect just fine to the Internet. The TiVos fail to connect. "Failed while negotiating" is the error message. If I go To View network diagnostics, the port configuration and DNS tests pass. The TiVo service connection test fails. I tried restarting the TiVo as suggested. This setup has been working great until today. The one change is that I had to swap out my old Linksys router for a new one that supports a VOIP phone line. But every other machine on the network can see out just fine after the swap. What can I do?
