Well, I now have the Web interface... But after clicking on the Download and install Full Web interface, it did its thing and then told me to restart... I so I did, restart the HDR but only to be presented with the same Web interface screen.
Now when I press on Download and install Full Web Interface, it reports:
Error 404: Not Found
File not found
With the URL being the IP of my HDR and /install.cgi
EDIT:
Ooh... Just switched the HDR from Radio to TV (after power cycling and putting it in and out of standby a few times), and refreshed my browser... and hey - got the full interface!
Looking good! And loving it! WOW scheduling timers via the Web! (Now have to find out how to and set up NAT so I can access the HDR from work!)
