Unable to connect to home Wifi from Samsung Galaxy SGH1897 due to Internet Security 2011

I think Internet Security 2011 is blocking me from adding home network via WiFi to me cell phone.  I can connect to other WiFi's with no problems.  Trying to connect to home WiFi, the phone sees the network, but can't get beyone "Obtaining IP address".

 

Assuming it is Internet Security 2011, how do I turn off Internet Security completely to see if it will then allow a connection?  Or do I have to completely uninstall it?
