As the title suggest, Ethernet port is dead (no lights when plugged in) on Roamio Plus. Had an old USB to Ethernet (Belkin 10/100) lying around so I gave it a try. It allows the Roamio Plus to connect to the internet, download updates, and even streams Netflix with no problems, no hesitation, no stuttering. Tivo mini in the bedroom also connects to internet and streams Netflix equally well. HOWEVER, it will not play live TV or recorded content from the Roamio without severe stuttering (plays 1/4 second, then pauses for 1 second.) So here is more background: Bought Roamio and Mini about 3 years ago. Had both connected via cat6 ethernet to Xfinity combo router modem. Everything was good! May 2017 Returned rented Xfinity modem and purchased modern Motorola modem/router Still connected via cat6 ethernet. Everything still good! September 2017 Just before or after Hurricane Irma passed, it no longer connected to the internet. Diagnosed ethernet port dead - no lights whatsoever on the ethernet port. (Confirmed with multiple cables to multiple ports on modem. All cables worked perfect with all router ports when testing them with the Apple TV sitting next to Roamio. Problem #1 Roamio can't connect to router / internet (tuner still works fine!) Problem #2 Tivo Mini can't talk to Roamio (due to Roamio ethernet being offline.) Plan B I happened to find an old Belkin USB to ethernet adapter (10/100) that I had used years earlier with an old series 2 Tivo. So I give it a try. This is slightly strange, but probably no surprise to techies…. IP address is assigned. Roamio connects to router & internet. However, on network setting pages, it shows "Ethernet Off" but yet shows the current IP address. So, I think the logic here is that "Ethernet Off" is displayed because there is nothing plugged in / nothing detected on the built-in ethernet port. But it does in fact have an ip address assigned through the USB adapter. It streams content from the internet - like NetFlix. Everything seems normal. Everything is normal EXCEPT the Tivo Mini in the bedroom WILL NOT play live TV or recorded content from the Roamio without extreme stuttering mentioned above. The Tivo mini WILL stream NetFlix from the internet just fine. So my somewhat old USB ethernet adapter works just fine for single Tivo purposes but does not play nice with Tivo Mini. Have rebooted both units many many times. Have spent considerable time on the phone with Tivo support. Also tried assigning static IPs to no avail - though I didn't make any configuration changes to the router. Not sure if anything is required on the router side or not. Didn't want to monkey things up since this router works with everything else and has been working fine since May with both Tivos. My Roamio appears to not have WiFi. It doesn't show up as an option under 'Network Settings.' Plan C Attempted MOCA Having just set up MOCA on a different pair of Tivos at a different address, I thought I would try to do the same here. If the Roamio can continue getting internet access through the USB/Ethernet adapter, then I can set up a MOCA network (with ROAMIO as the bridge) to connect to the Mini that way. HOWEVER, when I begin configuring for MOCA, even though I have an IP and internet access, the MOCA process stops because its looking at the built-in port and reminding me that I don't have it plugged in or access to the internet. Even when I tried with a cable plugged in and connected to the router, I still got the same message - "unplugged" because the port is toast. So using the built-in MOCA is not an option since it seemingly insists on using the built-in ethernet port. Also, the new Motorola Modem/Router does not seem to have MOCA capability, unlike the modems supplied by Xfinity. Plan D I'll try a different and more modern USB/ethernet adapter and maybe that will play nice between Roamio and Mini. So I purchased an "Ativa" brand USB 3.0 to ethernet adapter - figuring it should be backwards compatible to USB 2.0 (which is what the Tivo ports are) from the local office supply store. I would have preferred to buy a name brand like Belkin, Linksys, etc… but their Ativa was the only brand in the store. Brought it home, plugged it in….. No Joy! The lights would blink away on it but I wasn't even able to get an IP address assigned with this unit. Perhaps the Tivo doesn't have the drivers for these new adapters? So my questions are: 1) Has anybody had any luck using a USB/Ethernet adapter to connect a Roamio or Bolt to a Tivo Mini? If so, what brand & model? This would be my preference because it's a simply plug and play and won't require any configuring. And it would likely be the cheapest option to restore functionality to the Tivo Mini. I'm am considering purchasing a newer Belkin USB adapter, maybe a 3.0 version (though I know I'll be limited to 2.0 speeds) and see it if performs any better. 2) The other option would be to switch to a MOCA enabled router/modem. That would completely bypass my ethernet situation. Welcome any recommendations for Modem/Routers with this ability. 3) Use a stand-alone MOCA bridge. I don't have any experience with these but welcome comments suggestions on these too. Thanks for taking the time to read this not so short story and thanks in advance for any suggestions or advice!
