Just a heads up, BT HomeHub users may have or not noticed, that they are now advertising BTFON and BTOpenzone from their HomeHub, effectively a Public WiFi Spot!!
Now after ringing BT and asking to switch this off I was met with the stupid ass questions of what O/S are you using and how did I find this out, I hung up in the end!
Firstly to check you are advertising it, login to your HomeHub and click on Services Tab and where it says BTFON it will say either Deactivated or Activated.
this has been introduced as a Opt In scheme and to Opt Out you need to go to http://www.BT.com/btfon
Enter your BT Login details and then scroll down and login again on the Opt Out section.
