手机在刷国际版或类原生系统后,连接国内的WiFi网络会出现WIFI无网络或者连接能力受限的提醒,一定程度上影响使用。


其原因是:Google在Android 5.0后引入了 【Captive Portal】机制来检测WiFi网络认证,以判断WiFi的网络连接性。
aosp默认会将默认检测的服务器设为Google自身的地址,而中国网络环境特殊,无法直连Google,类原生及外版系统
默认都是以Aosp规范作为检测依据,顾导致此问题。


解决方法
注意提前打开开发者选项的【USB调试】【USB调试(安全设置)】
使用adb命令对【Captive Portal】服务器地址进行修改:

1.删除原有的服务器设置

1
adb shell settings delete global captive_portal_https_url
1
adb shell settings delete global captive_portal_http_url

除了使用上面两行删除命令,还可以直接将原参数修改为0,同样可以达到同样的效果,命令如下:

1
adb shell settings put global captive_portal_mode 0

2.设置新地址

1
adb shell settings put global captive_portal_http_url http://connect.rom.miui.com/generate_204
1
adb shell settings put global captive_portal_https_url https://connect.rom.miui.com/generate_204
