Yes, as I've indicated, wifi is turned on the iphone, connected to a wifi network.
The wifi button is on for the computer, and the computer is connected to the same wifi network.
The wifi network works fine for all browsing, in chrome and internet explorer.
Dragon is opened and active on the computer. I have tried to set up the Remote audio dictation machine profile, but that requires connection from the iphone to the computer, through Dragon Recorder.
Back to the same problem: open Dragon Recorder, open Options, click Wifi Sharing, get the message "Wifi: No Connection!"
