Why do you insist on private routers for boarding houses at higher education institutions: technically speaking, it's difficult to get through?

The private connection equipment is variable in shape and deployed at random, analysing common bypasses and corresponding detection entry points.

Private connections are often banned, either because equipment is cheap or plugged in, or because many routers have turned on AP isolation or modified MAC to create barriers to identification. The mere “checking” of houses is costly and resilient.
