6 tuner roamio ( updated but no hydra ) connected to Netgear Nighthawk X6 R8000 router via ethernet cable, and 3 mini's hooked up via MOCA. ( POE filters in place ) All work flawlessly in terms of watching TV and recorded shows. However, when it comes to netflix, HBO, Amazon, etc... I have issues related to sporadic connectivity speeds on all streaming apps. When it's working, netflix speed test on main box will typically read 40 Mbps+.. may work for hours, or days with no issues.. then BAM..... falls to basically nothing... like 0.03 Mbps and nothing plays. TIVO still can connect to download guide service.. albeit slowly.. netflix still says connection ok.. but it's just to slow to watch anything and Prime and HBO won't connect at all. No amount of rebooting of tivo box/minis, routers, Spectrum modem, will clear the issue. What I found does, is to physically replace the ethernet cable from the Roamio to router, with one of a different length, run test again and 99% of the time the problem goes away. I can then plug back in the original cable and it will work... but if I simply just unplug / replug in the same cable without a different cable first.. it will not work. I can also switch to wireless connection when I'm having issues with ethernet cable connection and it will work. ( can't keep it that way due to MOCA required for my minis' ) Everything else on my network works... speed test reaches up to 380Mbps on a direct hardwired computer into the same router when the issue is happening on Tivo. Static IP addresses are assigned in tivo and reserved in my router. I've tried a different netgear router, using switches to isolate the tivo.. you name it but to no avail. I have searched these threads and found similar issues with network speeds.. but nothing that seems to directly relate to my issue and the fix of plugging in different cables. Does the resistance of the cable length somehow trigger the tivo box to communicate back to router to reconnect??? Tivo tech support had me do the basic unplug and wait dance a few times but had no real clue as to what is really going on. Don't want to send my box to tivo to look at repair / replacing as I really think it's some kind of issue I can resolve eventually through some settings on tivo, router, ??? with the help of this community. Plus I have a 6tb drive I dont' want to lose my recordings on. Rant over.. ;-) Open to whatever at this time before the wife makes me turn all my tivo hardware into boat anchors.
