WiFi Speed Labels
Another exciting new feature from Android 8.1 Oreo (which only Nexus and Pixel users have so far) is WiFi speed labels. This is a small change, but one that's pretty helpful.
Basically, our Android devices can now check how fast a WiFi network connection is and will display the information right in the WiFi menu on your phone. That way when you see multiple wireless internet connections, you'll see which one is fastest, and know which one to connect to.
As you can see from our image above, Android 8.1 Oreo now lists WiFi as Slow, Ok, Fast, or even Very Fast. This just saves you from connecting to the wrong one and having to reconnect at a later point. It's a small but helpful change.
