The first day i had the vero i managed to stream 4k over wifi with no issues at all. I was was super impressed. Couple of days later i was having issues with streaming with buffering when there was none on the first day. I tried a powerline adaptor and also had issues with buffering. I decided to install iperf to diagnose the issue.
Please could some review these stats and let me know if they are good enough for 4k streaming.
I feel they should be, there are errors but not many. I also tried powerline adaptors which got very similar results except without any errors at all. I rebooted after changing network adaptors.
