I have blocked MAC address and used SMart Home Manager but unknown device is still connecting to my wifi
There are unknown devices connecting to my WiFi. After blocking the MAC address through the online sight and blocking internet service through the Smart Home Manager- their usage is still substantial. The usage is more than mine and significantly slows my internet down. Why is this happening and why do the features within the manager NOT actually work? I am approaching almost a year after my initial complaint and this is still happening. I at least want to know who they are even if I have to speak within myself- it has to be someone within 300 feet right?
