I have an Android TV box. I used WIFI connection because I cannot run a cable. But WIFI is getting worse as more people are working from home during the day. I added an ethernet connection using a powerline adapter (i.e. the Android box can access internet either using ethernet or wireless). I understand that powerline adapter is not the same as using a direct ethernet cable. But speed test shows that it has better speed than the WIFI connection. My observation with my Windows PC is it will always use the ethernet connection first and will automatically switch to WIFI if ethernet is bad. Please correct me if my observation is wrong. But for the Android box, I cannot figure out what it is using. I went to setting and saw both connections exist. I started watching my movie and notice that it is choking. I am not sure how to determine if it is choking on WIFI or the powerline adapter. I disabled WIFI and it worked fine again. I could stick to the powerline and forget about WIFI. But the powerline adapter is always impacted by high interference devices such as Vacuum , hairdryer or microwave. That's why I hope to keep both connections if Android has some smart to pick the one that has better throughput.
