Previous articles have briefly explained the basic knowledge of wifi. For more information, see WiFi learning for Android (1 ). On this basis, this article further improves program functions, the main functions are to enable the wireless network card, disable the wireless network card, check the network card status, scan the network, scan the results, connect to wifi, disconnect WiFi, WiFi connection status.Run the following command:Connecting to wifi
enable automatic dialing.
2. view the connection status
If you want to know the connection time of the Current ADSL dial-up broadband Internet access or query the connection status, follow these steps:
◆ Click Start> Settings> control panel in the task bar to open the dial-up network window. In this window, you can see that an available connection is established under "LAN or Internet connection". The default name of this available connection is "Local Connection ".

Javascript Network Monitoring and javascript Network Monitoring
This article describes how to implement network monitoring using Javascript. Share it with you for your reference. The specific implementation method is as follows:
This code can monitor whether the network is connected and the speed of the network.
(Function () {var network = function () {var monitor = this;/*** @ param {Funcation} speedInterval */var speedInterval = null; /*** @ param {Function} networkInterval */var networkInterv
