Resetting WiFi

Is there a way to reset which wifi network Konnected is connected to?

I tired going to it's ip address on my network. 192.168.1.64. But, nothing shows up.

After the board was added in Smartthings an option comes up to edit wifi. Got it now. 

65coupie where did you see that option? I need to do the same thing but have not found where to edit wifi.
