Hello: I have an AX50 router. I want to be able to block my daughters devices (wired and wireless) when i want from my pc. I can see a block command from within tether app but i want to do this from my PC and i don't see same control level anywhere?

Also a second question if i may???? How can I simply rename the clients (wired and wireless) from my PC controls so I can make them something I know and understand? I know the PC's behave according to what i name them but other devices are just some odd number and hard to track by IP or anything else. 

Thanks, Jonathan
