   What, exactly, is your (unspecified) "this router"?  Look for "Model"
on the product label.  Firmware version?  Connected to what?  Configured
how?  Any useful information at all might be more helpful.

   Why, exactly, did you buy your (unspecified) "this router"?  Is there
some actual problem which you are trying to solve?

   You apparently have more than one router.  Which is typically a bad
configuration.

   Most likely, you should not have more than one of "these domains"
(subnets).

   Think, for a moment, about how little useful information that
non-description conveys to the non-psychics in your audience.

   What leads you believe that the _device_ is the problem?
