Advertisements The issue I am having is with Multi-Room Viewing. Some background: I have 4 TiVos with the newest one purchased 2 years ago: 1 Series 2 (S2) 1TiVo HD (HD) 1 TiVo HD XL (XL) 1 TiVo Premiere (Prem) These have always been connected for multi-room viewing and have never had an issue with them working. The network configuration is a cable modem (ARRIS TM502G) connected to wireless router (ASUS NT-66UBlack Knight). The S2, HD, and Prem are all connected with wireless G adapters. The XL is connected using a powerline adapter (Zyxel PLA4205). I also have TiVo Desktop with published Music, Photos, and Videos to all 4 TiVo units. Now for the problem: About a month ago, the XL stopped being able to see the other 3 units and the published content on the PC running TiVo Desktop. All of the other 3 can see each other and MRV works fine. About 80% of the time, they can even see the XL and transfer from the XL to themselves. The XL can connect to the TiVo servers and get daily updates. It can connect to Netflix, Amazon, and YouTube. I can download shows from the XL using KMTTG. If I reboot the XL, the other TiVo units (and the PC content) show up for a short period of time, roughly 1-10 minutes, and then they disappear from the Now Playing List and you cannot connect anymore. During these brief times that I have been able to connect, I have even requested a show to transfer and about a minute after it started, the other unit disappeared from the screen but the transferred continued to completion. Over the past week, I have spoken to TiVo Customer Support at least 6 times. We have tried everything: Power cycling the entire network structure and TiVo units Connecting from one of the other units to the XL in hopes of forcing it to recognize that the other ones exist Connecting to each TiVo via a browser back door to prove that the router could see it and no ports were blocked Changing the network settings to get an IP address from the DHCP server Changing the network settings let the TiVo determine its IP address Changing the network settings force it to use a particular IP address (each of those last three work for about 5 minutes and then back to the same issue) Calling customer support takes 30+ minutes to even speak to someone and each time they take another 5-10 minutes to read all the accumulated notes. They have consulted with their Level 2 support and tried many things but still to no avail. The final thing I was told last night was that it was the powerline adapter that was the problem. They could not tell me why it was problem since the XL connects fine to the router for everything else and the other 3 units can usually see the XL connecting through that same adapter. Does anyone have any ideas? Im willing to try most anything at this point. I would rather not just get another wireless adapter because the XL is 2 floors from the router and in a media closet and so the connectivity is not great. Anything else?
