Problems with video streaming from NAS
I have massive problems streaming video files from my NAS to my android tablet. Maybe someone can help.
My setup is:
- Orbi RBK40 on the first floor in AP mode, connected via cable to my router.
- One RBS40 satellite in the basement, connected via cable to a Synology NAS and a QNAP NAS.
- One RBS40 satellite on the second floor, connected via cable to my NVIDIA Shield TV.
Everything is on the latest firmware 126.96.36.199.
My main reason for buying this system was to be able to stream videos from my NAS to my Shield TV and to my tablet / phone. I mainly use Kodi for this, accessing the NAS via NFS. Sometimes, I also use Plex.
Copying files from the NAS to the Shield or tablet, I see datarates of 10-13 MB/s.
I also see these datarates with iperf between the NAS and the tablet:
[ ID] Interval Transfer Bandwidth
[ 4] 0.00-10.00 sec 133 MBytes 112 Mbits/sec sender
[ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams
[ 4] 0.00-10.00 sec 978 MBytes 820 Mbits/sec 0.176 ms 83867/125130 (67%)
So this should be plenty fast to stream everything, including my uncompressed Bluray rips (which will use up to 6MB/s)
Now if I try to stream movies via wifi, I have massive buffering problems. I am talking 10s buffering, 5s playback, 10s buffering, 5s playback...
Once I connected the Shield TV via cable to the 2nd floor satellite, those problems disappeared completely for the Shield. Unfortunately, this is not a solution for my tablet or phone... However, this can't really be a bandwith issue, I am talking about 1m distance from the satellite without any obstruction.
My old wifi solution before the Orbi was the router built-in wifi and a cheap wifi range extender from TP Link. With these components, my data rates were much lower, but I never saw those buffering problems. It seems to be an Orbi-specific problem, maybe something to do with QoS settings.
I already tried doing a factory reset to all components and re-installing everything, but with no success. I have absolutely no clue how to solve this problem. I like the perfect wifi coverage of every spot in my house, but if I can't use this to access the data on my NAS, I can't keep the system.
