Ever since "upgrading" to TE4 earlier this year my router will lose its internet connection to the cable modem from time to time until one of the Mini's is unplugged. It's not always the same Mini. When we lose internet I start unplugging the Mini's one at a time from the switch and when the offending Mini is unplugged the router instantly reconnects to the modem. Plug that Mini back in and the internet connection is gone within 30 seconds. Tivo has given me a cumbersome procedure to reset the Mini and it may last a while but the problem always returns. We travel a lot and when this happens not only does nothing record but I have no access to my home network to access files, cameras or anything else. Short of reverting from TE4 - which means losing all recordings - has anyone heard of this issue and a permanent fix? Worst case, I can put all the Mini's on a seperate switch and turn it off when we travel but that shouldn't be necessary. Customer service says I'm the only one with the problem but I don't believe that for a minute. FWIW, I have Comcast service coming into my own Motorola DOCSIS 3.0 modem connected to an ASUS RT-AC1750_B1 router with all ten Mini's and the Roamio Plus connected via Ethernet to a Cisco 24 port unmanaged gigabit switch.
