Hi@Dmytro_Korolkov,
Thank you for reporting your need to our community.
Generally speaking, advanced functions mainly work on devices on the main network.
May I know what is the model number and hardware version of your router?

Access Control or Wireless MAC Filtering is used to block or allow specific client devices to access your network based on a list of blocked devices (Blacklist) or a list of allowed devices (Whitelist).
The function name might be different on different router models, please follow the steps below to set them up:
1. For Access Control, you may log in to the router's web management interface, go to Advanced > Security > Access Control to configure Whitelist or Blacklist. You could also refer to this FAQ for more details: How to configure Access Control.
2. For Wireless MAC Filtering, you may log in to the router's web management interface, go to Wireless > Wireless MAC Filtering to configure Filtering Rules. You could also refer to this FAQ for more details: How to configure Wireless MAC Filtering.
