My router decided to reset itself today and lose all the settings. I had to put them in as I suggested above and it all seems to work.
Not sure why it didn't before but if yours doesn't work try switching it on and off from the back or barring that reach for a paperclip and locate the reset button. Be sure to not press this reset for longer than 8 seconds or you'll lose the software installed by your ISP.
Make sure you change the 'configure' AND 'expert configure' settings as I describe above as they both need to refer to Voxalot.
Maybe the original poster of this question didn't change both settings?
