   I don't know what "primary" and "secondary" mean (to you) with
respect to routers.  Which one where you expecting to connect to which,
how?

> [...] I just don't know how to.

   Clearly.  You might start by describing your "my router" devices in
more detail (say, by a model number), and then explain what the problem
is that you are trying to solve.  If your "my Netgear router" is the
C3000 which the forum has filled in, then that may limit the
possibilities.
