Happy with 802.11ac networking transfer speeds for TiVo environment

I added three TiVo’s to my home setup using 802.11ac wireless networking, and wanted to share my positive results.



I have 5 TiVo’s, two are Roamio’s and three are Premieres. One Roamio and one Premiere are physically connected to my switch, and the other three TiVo’s are connected wirelessly using 802.11ac wireless hardware as Ethernet bridges.



My primary wireless router is the Netgear R6200, and then at each of the three remote TiVo’s I have a Netgear EX6100 range extender. The EX6100s have a single physical Ethernet port, and each TiVo is plugged into that port on its designated EX6100.



Each EX6100 is configured to act as a wireless bridge, meaning that it is connecting to both the 2.4ghz and 5ghz AC wireless networks, and I have disabled the capability of the device to act as a wireless access point. This means that all of the bandwidth of the device is available for internet connectivity as well as TiVo streaming/downloads.



In throughput testing I consistently achieve results where I can transfer an hour-long HD program (5GB) from one of the wireless TiVo’s to another wireless TiVo in 16 minutes, on average. This works out to about 40Mbps of consistent throughput when *both* TiVo’s are wireless.



When the transfer is from a wireless TiVo to a wired TiVo, the throughput is almost exactly doubled, and I can transfer the same hour-long HD program in 8 minutes, or about 80Mbps of throughput.



If I download the program from one of the wireless TiVo’s using pyTiVo it takes just under 30 minutes, or about 24Mbps.



The reason for moving to wireless is that we bought a new house that was built in the 90's, and it has no usable technology wiring to speak of. There are a couple of locations with coax, but unfortunately I have to use amplifiers at each location which blocks MoCa. Even if it wasn't blocked, I tested with MoCa without the amplifiers and found it to be buggy (TiVo reboots, failed transfers and streams, etc).



To run Ethernet cabling to the locations would require tearing into the walls and floors/ceilings of a two story house, and I didn't want to go to that trouble or expense. So, I opted to give it a try with the faster 802.11ac networking, and it has worked like a charm.



Bottom line is that after a week or so of use I haven't had any transfer, streaming, or internet issues to speak of. I just wanted to share this info in case it proves helpful to anyone else considering the move to 802.11ac wireless.
