Lol, LD is in computer, we have been dealing with the teen boy

ones, many stories and hard times :-(  ,  we are still using Linksys though ( had two of them, bought 2ed one to replace the old one as it has more functions)

Beside that, cut power works too, but as the last resort, so I bought a safe ( from costco, with hole)  to put the main moden in, and then bought a timer to cut the power supply at set time.  Those are on top of the Linksys, because the kids know how to reset the Moden, and bypass the linksys.   Anyway, I am not in computer....  but after all these years...  

Last thing,  after the whole house off WIFI, it is still not the end,  somehow, he discover his cell phone allowed him to access the free neighbour's open hotspots  by his cell phone provider, so we changed his cell phone plan... oh, all of those struggles....  

Good luck to all the parents with boys...
