This evening at home WIFI connection with a computer, can not be found online, but the phone was able to connect the Internet, looking for a bit simple reason, just think of it during the day in the company, with a computer connected to the company's intranet WIFI, modify over-IP address, specifying the IP address of the wireless connection, so this time, although the connection on a home WIFI, but the IP address is incorrect, it is not on the net.
The solution is to:
Control Panel Network and Sharing Center ----- ----- ----- Change adapter settings to find the mouse connected WLAN ---- ----- right click and select Properties to find the protocol version TCP / IPv4, double-click ------ change IP to automatically obtain IP, and then click OK on the line.
