KeepWiFi

KeepWifi đảm bảo WiFi của bạn nằm trên, ngay cả khi điện thoại của bạn đang ở chế độ ngủ.

Annoyed by observing your WiFi connection switches with 2G/3G when your cell phone takes its pause?

This service will keep your Wifi connection on air, even if your phone's screen goes off.

There is also an extended version (KeepWiFi locale) with Locale Plug-In and you can use to it say thank you.
