   You have one of those?

   "the place that we are in"? Do you mean that you are in a building
which provides Ethernet connections for your Internet service? If so,
then a cable modem like a CM400 woud be generally useless to you, with
or without any kind of adapters.

   "the internet provider"? Care to elaborate?

   _That_ is true.

   I doubt it, but from your description of your situation, it's hard to
be sure.

   MoCA adapters are useful in a situation where you have a co-axial
cable run, but you wish that you had an Ethernet cable run between the
same points. If you do _not_ have a co-axial cable run, and your only
co-axial thing is the CM400, then you don't want MoCA adapters.

  Hello, to you all,
  
  Let me try to detail this out, and perhaps there will be better resolution,
  I work for the AAFES, on a military base, the internet provider that supports all of the base have ethernet connection for the room only, the Netgear routers have coaxial connection only ( three or four models) that we have set on POG, and so we can't sell them as they would need some kind of adapter that will convert the coaxial to ethernet connection thru cat5 cable.
  Is that possible? is there aby adapter available.

       Ok. As I suspected/feared.

       That sort of adapter would not be practical. MoCA is not what you
    want, despite its having the right types of connectors.
    
       CMxxxx = cable(-TV) modem, totally useless without a cable(-TV) ISP.
    
       Cxxxx = cable(-TV) modem+router, not useful as a router without a
    cable(-TV) ISP, but perhaps not totally useless.
    
       It should be possible to configure a model Cxxxx modem+router as a
    wireless access point, which might be of some use in your situation. It
    depends on what's behind that Ethernet jack in the wall, but running the
    experiment could be educational. For the details, see, for example:
    
          https://community.netgear.com/t5/x/x/m-p/1463500
    
       That's written for a Netgear C6300-as-WAP, but the steps are about the
    same for any other router (any make/model) which lacks a one-step WAP
    option. (Especially similar for another Netgear Cxxxx.)
    
       If the equipment behind the Ethernet jack in the wall permits, a WAP
    could provide wireless access, and perhaps another couple of Ethernet
    ports (depending on how many there are on the particular Cxxxx). It
    would not provide any privacy/isolation of the kind which a NAT router
    would. Whether anyone cares, I couldn't say. In that respect, it
    should be no worse than connecting a computer/device directly to the
    Ethernet jack in the wall.

  Thanks a lot, I guess we will have to return them all back to DC or vendor, or transfer them to another location.
  
  have a great day and thank you all for the time and help.
  
  stay safe.

       Yeah, it's likely that they'd be more useful to someone else as real
    cable modems/modem+routers. At least you dodged the MoCA adapters.

       And a suitably solemn Armistice Day to you, too.
    
    > stay safe.
    
       That sounds like your job, but I'll try to do my part.
