Hi @Michael badhan ,
Assuming you have the Sagemcom Wi-Fi hub then the staff here can disable this behaviour for you.
For one of the TalkTalk staff on this community to be able to look into this you will need to update your community profile to include your name, landline telephone number that your TalkTalk service is provided on & an alternative contact number. This will allow them to identify you, and they will then be able to help.
Don't post any personal details in this thread, just add them to your community profile.
Then they will hopefully be able to respond to this post within a day or two.
