Controlling Device on LAN

I'm having issues on network when I connect my fetch box to lan via ethernet. When connected via my wi-fi its fine but I would like use ethernet. 

 

My broadband NBN fibre gateway (device) is in the garage and that is connected to an 8 port TP switch which splits to 3 rooms and an alarm. 

 

The Nighthawk is connected via ethernet in one of those rooms. 

 

As soon as I connect the fetch box via ethenet in the other room - I loose the modem connection. The internet led on the Nighthawk switches is turned off and the WAN/Port 4 light also goes off.

 

As soon as I disconnect the fetch box ethernet cable, the wifi internet come backs via nighthawk with all leds illuminating as they should. 

  • OK Karl Murphy,

     

    Your setup is?:

    FIBER WAN-->NBN fibre gateway (device)-->8 Port TP Switch-->(Hardwired output to 3 seperate locations 1.2.3)-->1. Nighthawk Router, 2. Some other device, 3. Some other device

     

    I think if this is your setup then this a big problem...

    It should be more like:

    FIBER WAN-->NBN fibre gateway (device)-->Nighthawk Router-->8 Port TP Switch-->To 3 seperate rooms...

     

    Of course all depending on what ever NBN fibre gateway (device) is and how it is setup?

    Depending on how you have a "Cable Modem/Router" configured?

    I assume that this is hopeless, but I'll give it one more try.

       What's a "fetch box"?  This?: https://www.fetchtv.com.au/

       What is _that_?  Has it a maker and model number?

    Depending on what your (unspecified) "My broadband NBN fibre gateway
    (device)" is, that could be harmless (or not).  Does that gizmo have
    only one Ethernet port?  If so, then connecting it to a network switch
    might be your first big problem.

     

    > The Nighthawk is connected via ethernet in one of those rooms.

     

       What, exactly, is your "The Nighthawk"?


    > Model: C7000|Nighthawk - AC1900 WiFi Cable Modem Router

     

       Is that accurate?  Or do you really have some more suitable device
    (with a different model number)?  Look at the product label.  If you
    really _do_ have a C7000, then what are you connecting to its
    coaxial-cable port?

     

       Are you really trying to connect a C7000 to your (unspecified) "My
    broadband NBN fibre gateway (device)" (whatever that might be)?  That
    would very likely be a very bad idea.  What, exactly, did you connect to
    what, exactly?  (Hint: If a device has different types of Ethernet
    ports, then "connected to device" is not enough detail.)

     

    > As soon as I connect the fetch box via ethenet in the other room - I
    > loose the modem connection. [...]

     

       That's a connection between the Fetch box and the network switch?


       What, exactly, is your "the modem"?  Is it related to your
    (unspecified) "My broadband NBN fibre gateway (device)", or is it some
    other thing?

     

    > [...] The internet led on the Nighthawk switches is turned off [...]

     

       It was on?  Some color or other?

     

    > [...] and the WAN/Port 4 light also goes off.

     

       "WAN/Port 4"?  Do you mean "LAN port 4"?  That might mean more if
    anyone else know what you had connected to that port.

       It's nice that you're happy, but revealing which lights do what would
    be more helpful than whether they do, in your opinion, "as they should".

     

       You may not believe it, but your chances of solving your problem(s)
    may depend very heavily on your providing an accurate, detailed
    description of all your devices, and exactly what is connected to what.
    (Randomly generated model numbers are no substitute for accurate
    information.)  I'd start with your (unspecified) "My broadband NBN fibre
    gateway (device)".

      thank you additude - this has helped me a bit by suggesting when the nighthawk should be conneted. 

       

      My setup is?:

      FIBER WAN-->NBN fibre gateway (device mode is number G240-g it looks like a modem)-->8 Port TP Switch-->(Hardwired output to 3 seperate locations 1.2.3)-->1. Nighthawk Router D7000V2 AC1900, 2. Fetch Box M616T (disconnected from ethernet outlet), 3. No device

       

      Everything worked perfectly for me except in this set up

       

      1. I'm getting an amber led light on port 4/lan/wan internet. That the one connected via hardwired ethernet to the TP switch. It was never amber before - it has been white for months.

      2. When I plug the Fetch box into ethernet outlet 2 - the nighthawk looses its incoming internet connection. What i mean is that the led for port 4 is off and the led for the internet (that the one shaped like a globe) is off. I want to connect Fetch via ethernet to avoid so many devices on my home wifi network.

      3. Bosch Home alarm app cannot connect to the the alarm system when I'm out and above - meaning if the alarm goes off I dont get notified - (which is connected to ethernet to port on switch) 

       

       

      I think if this is your setup then this a big problem... Yes I agree but it was (acceptable to me) until I put Nighthawk into outlet 1. I think the reality is it was never working properly but acceptable to me. 

       

      It should be more like:

      FIBER WAN-->NBN fibre gateway (connection box g204-g )-->Nighthawk Router d7000v2-->8 Port TP Switch-->To 3 seperate rooms...

       

      Ok I can see why the above set up might work better. It also explains why the nighthawk loses connection when I connect other  devices into ethernet outlets, the TP switch might be causing the issue.  

       

      Will my switch slow my wired ethernet outlets down? The swithc is a 10/100?

       

      I get 47mps on home wifi at the moment and a touch more from ethernet outlet 3. 

       

      Of course all depending on what ever NBN fibre gateway (device) is and how it is setup? 

      It was installed as part of a newbuild. NBN docs I found online refer to it as a connection box and it has model g240-g on the front. Port marked uni-d1 is connected to TP switch.  The power and optical lights are green as well as uni-d1 led light. that all i can see. Looks like a modem

      Depending on how you have a "Cable Modem/Router" configured?

      I never made any changes to config out of the box. But since then, in an attempt to resolve issues with alarm, fetch box and solar invertor, I have updated the firmware. Reset it multiple times, turned it on/off and cursed at it relentlessly. 

       

      When trying to resolve the led amber light issue described above, I checked the ports on nighthawk by connecting ethernet from port 4 on nighthawk into port 1 on nighthwk and got two white leds on the nighthawk. I concluded that TP switch was limiting speed to 100mps. Then I tried to find out if I could change the port 4 speed to 1gigabit via the nighthawk webbrowser config control and concluded that it is set to auto-negotiation and cannot be changed on nghthawk from browser. I also checked the spec of the switch which is 10/100 which suggests it not capable of 1 giga which is strange as it was getting a solid led on nighthwk in the past. 

       

      This has taken up my whole weekend. I'm at the stage where I think I should pay somebody to come and fix it.

           Probably wise.  Someone on site should be able to read the model
        numbers on your equipment, which you seem unwilling or unable to do.
