安卓8.1可帮您选择最快的公共WIFI啦。

奥利奥发布之后，终于迎来了安卓8.0第一次意义重大的更新——安卓8.1，而且8.1还不断推出新的酷炫功能，比如说，谷歌今日宣布奥利奥将会显示公共WIFI的网速，帮助用户决定这些WiFi是否值得连接，而且会将WiFi的网速情况分为四个等级：非常快，快，普通，慢。

根据谷歌发布的声明来看，“很快”和“快”的区别在于，你可以使用前者直接看高清画质的视频而不用等其缓冲完成，而使用后者，你只能观看大部分视频。大多数的咖啡店的WiFi处于“普通”的等级，但是这种网速只能浏览网页，使用社交媒体和听歌。

公共WiFi是时好时坏的，但在您第一次连接WiFi的时候，不必去猜这个WiFi是好是坏，因为在您连接之前安卓8.1会直接显示WiFi的网速。

因为私人WiFi连接时需要输入密码，所以安卓8.1无法显示私人WiFi的网速，而且谷歌也不能随便地测试私人WiFi的网速，但是可以显示WiFi的信号强度。谷歌说，网络管理人员可以使用canary URL让安卓的WiFi助手不再显示网速信息。

This Android 8.1 trick will help you decide if anopen network is worth connecting to.

Some of the cool, more subtle features of Android 8.1are still rolling out weeks after the first significant update to Oreo wasreleased. For instance, today Google announced that Oreo will now display thespeed of nearby open Wi-Fi networks to help you decide whether they’re even worththe effort of connecting to. The Wi-Fi settings menu will now display one offour speed labels: Very Fast, Fast, OK, or Slow.

The difference between Very Fast and Fast, accordingto Google, is that you can stream “very high-quality videos” on the former and“most videos” on the latter. Most coffee shop dwellers should be fine with theOK level, as that’s enough for web browsing, social media, and Spotifystreaming.

Public Wi-Fi can be spotty. Forthe first time, AndroidOreo 8.1 lets you take out theguesswork & see the speed of networks before you hit connect.

Private Wi-Fi networks that require passwords don’t displayany speed data since it’s really none of your business and Google can’trandomly test them, but they do continue to indicate signal strength. Googlesays network administrators can also opt out of Android’s Wi-Fi Assistantshowing speed info by using a “canaryURL.
