RE: Router not honoring blocked devices, nor reserved IP addresses

I Have the same issue with a new router they just activated 2 weeks ago on Dec 3 , 2025. All devices that have their MAC in the "Blocked Devices" list allowed on the network.

Please help. Should I buy an off-the-shelve router but the behind Comcast router and set up the BLOCKED DEVICES" on this secondary router?

PLEASE HELP!!! Much appreciated !
