    Hi, I’m running v1.0.338 on two of my machines with Fluidnc Firmware. They work brilliantly BUT one machine always defaults to network search 10.10.10.1-254 which I always have to edit to 192.168.1.1-254. Is there a way to change this and can I save a ‘static’ ip so I don’t always have to search my network ?

    Check your PC NICs (network cards) one has a 10.x IP.. Disable/remove the IP. If your PC only has the correct IP it would default to it

    Thanks for your prompt message, I can investigate this. Interestingly my laptop and another PC in the workshop do actually correctly scan 192.168.0.x.
    In hindsite, my miller PC may not be connected to my network as I have been connecting to the controller by wireless network so this would explain things.
    The nextwork interface works brilliantly and has solved my electrical noise problems which we though were associated with usb noise.
    Thank to you and your team for creating this amazing program.

    Hello, in addition if it can help you.
    On my router I assigned (reserved) fixed addresses for Control, Interface and two PC's, I also defined a priority QOS for these four addresses.
    I hope it helps.

    on the PC that rescans, open a command prompt and type
    ipconfig /all
    and it will show you all the network connections it has got.

    On my PC which I knwo has got 2 adapters (the Gigabit is on the motherboard, the 2.5Gb is an adapter I added) it shows
    Code:
    Ethernet adapter Ethernet 3:
       Media State . . . . . . . . . . . : Media disconnected
       Connection-specific DNS Suffix  . : ate
       Description . . . . . . . . . . . : Realtek PCIe GbE Family Controller
       Physical Address. . . . . . . . . : 2C-F0-5D-6E-C7-C8
       DHCP Enabled. . . . . . . . . . . : Yes
       Autoconfiguration Enabled . . . . : Yes
    
    Ethernet adapter Ethernet 4:
       Connection-specific DNS Suffix  . : ate
       Description . . . . . . . . . . . : Realtek Gaming 2.5GbE Family Controller

       IPv4 Address. . . . . . . . . . . : 192.168.1.81(Preferred)

       Lease Expires . . . . . . . . . . : Monday, 05 May 2025 12:34:53
       Default Gateway . . . . . . . . . : 192.168.1.1
       DHCP Server . . . . . . . . . . . : 192.168.1.1
       DNS Servers . . . . . . . . . . . : 192.168.1.1
       NetBIOS over Tcpip. . . . . . . . : Enabled
    
    What you are looking for is which one is assigned an IPv4 address in the 10.0.x.x range, and then to determine if that is statically assigned or not.
    Your PC may have Ethernat and Wifi on board, and some desktop motherboards have 2 ethernet ports built in, and what Peter was suggesting is that one of them is assigned an 10.x.x.x address, so we are looking for that. Once you find it, you can turn off the static assignment in the Windows settings.
