I have had a mibox (walmart) working perfectly for the past few months.

This includes Netflix (at 1080p). Starting any show would be fairly instant, as I have a 1Gb/s internet connection.

However recently netflix has not been behaving well. Shows start very slowly (buffer for many seconds), play at low resolution, and sometimes fail to play at all, or constantly buffer during playback. This only happens on the mibox - other android devices and PCs on the same network have no issues. This happens on both ethernet and wifi.

This is not the 4k streaming problem (as I don't have a 4k tv), and the stream starts up and actually plays (albeit at low quality and constant buffering)

Very strangely though, some (very few) shows play perfectly. They start immediately, and play fine.

Has anyone else experienced this?
