Lots of bufferings when watching TiVo recordings or live shows
Here’s my setup: I’ve a Orbi AC3000, both the RBR50 & RBS50 are connected to my TiVo modem with CAT-6 cable. The TiVo modem has a router feature which has been disabled. All devices have latest firmwa...
This is the first I have heard of a "TiVo modem." The original TiVo boxes came with a dial-up modem to connect to a phone line, but this was before internet access was common. (I believe modern TiVo's no longer include one.)
Could you be more specific about exactly what product the router and satellite are connected to and who your internet provider is?
Your iPhone and iPad are connected to the Orbi and have a strong WiFi signal and you are using the TiVo app?
Thanks
My model of my TiVo modem/router is Technicolor DPC3848VM Docsis 3.0 Gateway. I’ve the Netgear Orbi AC3000, it has a router RBR50 & a satellite RBS50, both of them are connected to the back of DPC3848VM. Currently, the DHCP & WiFi functions of DPC3848VM have been disabled. My internet provider is Cogeco and I’m using their “Cogeco TiVo” app on my iPhone & iPad. Yes, the WiFi signal from Orbi is extremely strong (maximum bars). My house is only 2000 sq ft. The buffering issue only happened when streaming videos from TiVo & Plex. Prior to my purchase of Netgear Orbi, I do not have any buffering issues with DPC3848VM. The only reason why I purchased the Netgear Orbi is because the DPC3848VM can’t cover my whole house, some areas have weak WiFi signal. With Netgear Orbi, it covers my whole house with strong WiFi signal, but it’s not able to stream 1080p videos smoothly. Btw, I’ve about 40 devices connected to the Orbi.

The RBS50, if connected to anything, should be connected to the RBR50, if you want to use ethernet backhaul instead of wireless backhaul.
I agree with everyone else - 15 ft apart is too close - your devices are probably having a hard time deciding which Orbi to connect to as the signals are probably severely overlapping.
Your explanation makes sense. Thank you so much. I will order the Netgear Orbi AC3000 again and give it another try with your suggestion (RBS50 will be connected to RBR50 and try to separate them further).

Separate them as far as you can, even if the separation seems forced, like putting them right next to outer walls on opposite sides of your home. Try to get that minimum distance of 30 feet, but it's OK to have 50-70 feet between them as well. Think about it in terms of a bubble surrounding each device representing the wifi signal. If those bubbles overlap too much, you create a problem The ideal distance is the one that supports the highest speed connection between the devices while minimizing the bubble overlap. They have to overlap some to support a wireless backhaul connection, but if you are using a wired backhaul connection, then you can actually have them barely overlap at all.
I'm going to attempt to visualize this by showing different distances between the satellite (S) and router [R]. The satellite's signal is represented by parentheses below, and the router's signal by square brackets.
This would be ideal for wireless backhaul - enough bubble overlap to support a highspeed backhaul:
( S [ ) R ]
With a wired backhaul, you can separate them further, but you'd have a "dead zone" right in the middle of the two:
( S------)--[------R ]
What you had in your setup probably looked more like this:
( [ S R ) ]
Any device located between the the router and satellite in this case has two very strong signals under the same SSID, possibly causing the device to bounce between the two signals, causing streaming to be stopped and restarted over and over. This is the reason for a minimum distance.
