you always have the option of using your own router
I appreciate you are trying to help, but it's a poor solution since in many cases it means spending money on a new router when a perfectly good one is already in their possession.
the OP has just obtained a HH5 as shown on the BT.com website it has to be purchased anyway and if the fon/wifi service is an issue then rather than buying a device that is on as default it is as easy to buy a router that does not have the service on it by turning the feature of the enduser is the one losing out on a useful service while out and about
What about all the people getting a HH4 and a HH5 after signing up to BT? Should they buy a new router or perhaps maybe BT should fix it so that it does not take 28 days to opt out?
it does not always take 28 days that is the worse scene scenario
More often than not I've seen it take 28 days, or close to that.
as to most people they do not seem to worry about it as they see the advantages as it has little if any affect on your broadband service as the main user of the connection always has priority and if the connection is maxed out no one can use fon /wifi anyway and the service has been around since the hub 2
Once the user opts out of FON via the website they are not receiving any benefit from FON, so their router should stop broadcasting FON to others within hours in my opinion.
Sadly, whenever I've tried a factory reset on the HH4 is defaults FON to ON and does not deactivate it for weeks even if the user was already opted out on the website.
