WLAN is not connected via a port no. It only has an ip address.

`InetSocketAddress objEndPoint = new InetSocketAddress(IP, port);`for follwing what i should do? – shivani patel Apr 09 '13 at 12:12
Here you are trying to connect to a Server Socket which is initialised with a `port no` on a machine with its own `IP`. You need to know these two beforehand – asloob Apr 09 '13 at 12:15
ok...but port is not needed in WLAN so using ip address how to connect ? – shivani patel Apr 09 '13 at 12:17
You need to be connected to the WLAN before connecting to the Server Socket, ie. before doing this `InetSocketAddress objEndPoint = new InetSocketAddress(IP, port);` – asloob Apr 09 '13 at 12:18
