   Ok.

   You seem to be working much too hard.  If your (unspecified) "a new
3d printer" has a web interface, then what makes you think that you need
to talk to it over a USB cable?

   Which "A few commands"?  Who decided on "192.168.1.14"?  Why?  What's
the IP address of anything else on your LAN?

   Hint: Visit http://netgear.com/support , put in your model number,
and look for Documentation.  Get the User Manual.  Look for "192.168.".

   What, exactly, are you putting into the (unspecified) browser to get
what error message, exactly?  As usual, showing actual actions with
their actual results (error messages, LED indicators, ...) can be more
helpful than vague descriptions or interpretations.  Copy+paste is your
friend.

   If your router is a C3700, then the default subnet of your router is
"192.168.0.*", and "192.168.1.14" would be incompatible with that.  I'd

guess that that's the primary cause of most of your problems (so far).

   With my weak psychic powers, I can't see the user manual for your
(unspecified) "a new 3d printer", so I know nothing, but my advice would
be to reset the printer to its default settings, and start again.  Then:

   1. Connect an Ethernet cable from the printer to a LAN port on the
router.

   2. Power on the printer.

   3. Point a web browser at the router.  (As the C3700 User Manual
      says, "Type http://routerlogin.net or http://192.168.0.1".)  Find
      the "Attached Devices" page, identify your printer in the list of
      attached devices, and note the printer's IP address.  (Later, you
      may also want its MAC address.)

   4. Point your web browser at the printer's IP address.

   5. Do whatever you're supposed to do with the printer.

   6. If you want to find the printer at some particular IP address,
      then reserve an address for it, as explained in the C3700 User
      Manual under "Reserve LAN IP Addresses".  You may need to power
      cycle the printer for it to get its new reserved address.

   If that fails, then go back to your manual USB-terminal
configuration method, and choose an IP address for your printer which
begins with "192.168.0.", and then use that.
