I’m watching videos on my Pi3 in the bedroom. They are being streamed from the V4K with USB hard drive. V4K is hardwired to Router, Pi3 is using Wi-Fi.
Wi-Fi signal strength shows good, but the videos tend to play great for about 15 minutes and then they start to require buffering. Often they just stall out and the video closes, or the Pi3 freezes and I have to wait 5+ minutes for it to come back to its senses.
My guess is that its a latency problem getting to the V4k. Is there a good way to test this theory out?

It shows decent signal strength when I go to setup wireless (4/5 bars). Maybe I’ll run a continuous ping and see if something happens during the day. Signal strength could be spiking and I’m obviously not looking at it that closely when I’m watching a video.
Probably not within the next couple days (sick girlfriend), but I’ll try moving the setup downstairs to hardwired it when it won’t disrupt her watching plans.
Don’ t know anything about the keying message. That’s Greek to me.
I’ve updated some of my router settings. I’m going to put in a new access point (and I’m going to adjust the SSID to see if there might be a failover problem), and I’ll try the CRDA thing you linked to.
I launched 500 pings after I first posted and its pretty clear there is a signal problem.

I’m just kind of shocked that its this bad while showing a good connection, but now that I’m reading more about it it sounds a lot like the strength can be very misleading.
Just curious as to what router your using? My cheap Comtrend AR-5381u ISP provided modem/router combo pretty much requires at least a monthly reboot otherwise I experience the same issues.
I switched which fixed the problem. I’ve wired the first floor of my house, so I have a router in the basement and an access point on floor 1. The access point was an older netgear router.
Pulled the netgear and got a used ASUS RT-N66u from work to put in its place. Problem completely gone now.
