I am using wireless mac filtering on my router and I have provided access to 2 users but one of them is sharing his connection with many others through his Samsung Note9 which has function to act as a router and provide wifi hotspot. I don't want anyone to share my wifi connection without my authorization.
My concern is that that is unauthorized access to my internet and I don't know how to stop that sort of activity. Please let me know if anyone knows how can I stop that guy forwarding my wifi to many others. I cannot stop sharing my wifi connection.to this guy. If there are any router settings do let me know I am using D-link router.1
