Mini problems with powerline--potential solution
Several of us have had problems connecting the mini using powerline adapters. The symptom is that the Mini loses connection with the main TiVo, even though you can watch live TV. Also, when watching something, you may get random messages that the network is not fast enough.
I may have a solution (at least it worked for me). I have the TP-LINK adapters. They come with "Powerline Utility" software. I was using the default plug and play settings when I was having the problem. I tried playing with the "Advanced QoS settigs" and found that the "Voice over IP" setting worked for me. I don't remember what the default was, but it caused problems. Hope this helps someone.
