Thanks Dhawal. The login works.
What I was after was a way to set up the gateway from a computer. Entering and naming multiple devices is much easier with a real keyboard! I have since learned that thee best way to do this is with the iSmartenit AIR application from http://www.simplehomenet.com/support.asp?page_id=DL_Software which essentially is the iSmartenit app that runs on your desktop in a browser window. Very nice indeed!
Thanks to you and Justin for the wonderful support!
