Thanks for Sugguestions
Currenlty i am using IPv4 Filtering
I tried DDWRT but on ddwrt wifi sucks very badly cant even get connected outside my living area
also there is an issue or bug (dnt know if only i m facing or every one) , i can only create a total of 24 rules incl every thing like DHCp Reservation, filtering, schedule all total 24 , i will try to reset router and upgrade to FW 1.30 and see if it get solved
as i noticed just now Devices option has been removed from Managment>users>device
that option was for mac filtering
