It is a RPI3B. I am just trying to find the reason it has has steadily gotten worse over the last few months of upgrades. Netflix and now amazon prime both seem unusable due to screen lockup’s.

It does not seem to be the WiFi as hard wire did the same.

I swapped sd cards and did a complete reinstall. that did not help.

Being I am not computer person. I probably just need to wait and see. Thanks for the response and all the hard work.

"Screen lockups" - do you mean buffering, stuttering?

Make sure you've configured inputstream.adaptive to a maximum of 720p as the RPi3/RPi3+ cannot software decode 1080p without stuttering.

You can test your Wifi and Ethernet throughput using iperf, which you can install from the network-tools add-on (you'll need iperf running on another machine in your network to test the throughput between the two machines). I'm pretty sure the ethernet performance won't have changed, but your wifi is dependent on the environment it operates in, and that could have changed, but there's little anyone here can do about that - it's why Wifi is almost never recommended for streaming.

It's also possible your ISP is the problem, and your internet connection/performance has degraded during the last few months resulting in increased buffering.

If this were a common problem with these builds then more people would be reporting it, and they're not, so this sounds like a situation specific to your network, either your Wifi or your ISP. Run a speedtest on your internet connection to confirm you're getting what you expect, and iperf on your Wifi.
