Android Wifi with same name I want to know if i add wifi network with say ssid="test" can i anyway add same ssid="test" with different configurations like ip and gateways?

EDIT :

Suppose wifi has been configured with below configuration :[Added manually]

SSID : "Test"
Security : None 
and No Any advance settings provided.


Now can i add another wifi with settings below :

SSID : "Test"

Adding  any number of duplicate SSID's is possible if you have a unique IP address. 

In lay man's terms SSID is nothing but just an identification given to that particular network given to distinguish that network from others for simplicity. What defines that network is it's IP Address.If you have a conflict between an IP address then it may be a real problem.

For some devices(like Samsung) you need to check the to Display open Network connection if available in order to view open connections and for some devices it shows by default.

Ex:-Let's say you have two network's with SSID as Test.
Test1 has an open connection available for public use and Test2 is for personal use and is encrypted. Your mobile device will simply connect to a network whose signal strength is good. As the IP address is different there will not be any conflict and you can do your browsing.

In case there's any  conflict(same signal strength) then the device will ask the user to select the desired network or search for a new network.

Caution:-Browsing an open network for reasons related to finance leads to severe security threats browse at your own risk.

An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there.

The most simple definition for IP Address I could give is-

IP address act as you house address to which the shipment has to be delivered.If you have two same addresses then to whom will the shipment be delivered.
