Operation Steps:
To increase the WiFi safety factor, you can turn off DHCP without wiring, so that when you connect to WiFi, you need to set up a static IP.
Here's how to set up static IP under Android 4.0.
Note:
1, open wifi;
2, click on the need to connect the WiFi access point name;
3, enter the password, the input method hidden will find "Display password" and "Show advanced options", or long by signal, pop-up window "Modify the network";
4, check "Show advanced Options";
5, the next pull will appear "IP Settings";
6, change the DHCP in the option to "static";
7, change to static later, the following will continue to appear several items, fill in the following way:
IP Address: Your mobile phone's IP address, is generally 192.168.1.XXX (XXX can be between 2-254, can not repeat).
Gateway: The IP address of your router (most routing default IP will be 192.168.1.1).
Network prefix Length: Do not need to modify.
The IP address used by the domain 1:wifi access point, typically 192.168.1.1 or 192.168.0.1, should refer to the settings on the route. You can also use a different DNS server address.
Domain 2: The same as the domain 1 can be.
