receive 2.4Ghz signals. 3, choose the most suitable channel Similar Wi-Fi networks can interfere with each other as the neighbors ' cordless phones interfere with each other. To solve this problem, the router needs to switch the channel it uses, Miller said. Most routers can automatically switch channels, but manual settings can be a better idea, especially if there is a blind area of the signal. "If there is a blind area-usually far away from the wireless router, open airport Utility in th
The priority rules for the current Android WiFi auto-connect are as follows:1, the priority value of the range is set to [0,1000000], if beyond this range will reset;2, the most recently connected AP has the highest priority, in the automatic connection will first try to connect it;3, not connected but scan to the AP, according to its signal value of the strength of the order, the stronger the display of th
Unity provides two ways to enable developer's Android device to connect to the profiler for performance analysis:1, through the wifi,android device and the computer in the same WLAN.2.
