I wrote a message on the forum 3 years ago about this issue. I managed to figure it out going via the website. This is my thread and solution;
I tried to follow the things I'd done in my solution. But I can't seem to find where BT WiFi is in the MyBT extras page.
This seems to coincide with a new firmware update: SG4B1000E020
Does anyone have an idea how I can turn this BT hotspot off?
Edit: I found where the bt wifi fone page is, but it wants me to sign up to it. Do I sign up then remove it, or if I sign up am I committing myself to some kind of contract? This is very overly complicated.
It's possible you need to be signed into your account for this link to work, but here's how I get to the opt in / opt out point.
Thank you for the link.
I found this page before. I'll attach a picture of the screen I'm seeing. Do I need to set it up and then turn it off?
