To turn it off on the Smarthub you need to opt out of BTWifi. If you Opt out of BTWifi you can not use it when out and about. It can take weeks to turn off.
For information, your private network's bandwidth gets priority over BTWifi so if you need it you get it. It will not be taken up by people logging onto BTWifi.
The BTWifi signal will have been broadcasting since the day you first switched on your Homehub so it will not just have activated with you having used it recently.
I doubt it is the BTWifi that is causing your Netflix problem. As I said, if you need the band width you get it even if that means there is none left for BTWifi.
Have you personally opted out of BTWifi. It will not be turned off on your Homehub until you do.
I agree, I was surprized to see my wifi status has been turned on and no off switch. What a complete shambles. Didn't know all this was in the contract. Now I have to go thru all this trouble to 'OP' out why tamper with someone's HUB in the first place. Very dis-respectful of BT.
Up until now I was happy with my package.
Total shambles & let down by BT
home hub 6...
I have the same problem BTwifi set to active on the home hub after an update, i have not activated this on my extras so it should be off...
but here is the other nasty suprise, as soon as it set to active after an update it kicked of other devices that are conected via the home hub wifi... and they struggle to conect at all after that
at the same time, all the PCs conected to the home hub via RJ45 cables start to have problems conecting until i give them a static IP...
this is not quite what I expected from any router least of all one that is advertised to be one of the very best for wifi...LOL
