I've had a similar problem. I suspect that the DVB-T I'm using is conflicting with the WiFi Detector. The reason is that with one dongle I get the final message on the boot screen to say that the gain of the DVD-T has been set and with another wifi dongle the error message that the wifi dongle cannot accept the command.
Only seen a WiFi Hotspot on the iPhone but not seen on the iPAD and only with one of the WiFi dongles. I also have a WiFi sniffer software package and cannot see the WiFi hotspot on one but have the on the other.
Bottom line is like you bought what was specced but so far not getting a working system.
Ordered a second DVB-T if that does not work then I am not clear where to go from there.
