Been trying to register and sync Vodafone Sure Signal V3 for a week. Vodafone Chat Line hopeless. Is this a firewall issue?
My Sure signal connects to my router but is then unable to register or sync with the sure signal site.
Make sure you have turned off "smart setup" on the Homehub.
See link how to do that.
Have a look at this video to see if you are setting it up correctly.
