How to add a LAN and assign an IP address

Anonymous

We have been using Windows 7 on an old Dell Latitude D820 laptop for remote monitoring of an inverter. Have recently purchased a Lenovo Thinkpad which is running Windows 10 Pro. Need to set it all up on the Lenovo with Win10. The software is all setup, however it needs a network connection.

Some information on the Windows 7 laptop. The one below is what the inverter requires to connect.

The next 3 are how the Local Area Network is setup, and how the IP address is defined.

Given the above information, how do I (i) Add a Local Area Network on Win10 and (ii) assign an ip address of 192.168.1.101

I did start to look at doing this, but the network setup on Win10 is quite different. Like I could only see "Ethernet" which indicated a connection to the internet. Also the network properties had both IPv4 and IPv6. I assume I only configure IPv4.

One thing about this network is that it is a completely CLOSED network, no internet connection, only the LAN going to the inverter. From time to time I do connect to the internet, but only for Windows updates and Lenovo updates, and then revert back to LAN only.

The network is all hard wired, CAT5/CAT6, no wifi/wireless.

    Hi, Cephas777. I'm Robinson, and I’m happy to help you today.

    The "Ethernet" is the correspondent to the "LAN" option on Windows 7, you can use this procedure to configure the IP using the Control Panel.

    1-Right-click on Start then click on Run

    2-Type: Control Panel and click on OK

    3-Click on "Network and Intenet" then click on "Network and Sharing Center"

    4-Click the "Change adapter settings" option on the left navigation pane

    5-Right-click on the Ethernet adapter and click on properties

    6-Search for the option Internet Protocol Version 4(TCP/IPv4), select it and click on properties

    7-Then you just need to set the right IP and save the changes

    Well it's a good outcome really, as I just tested the laptop connected to the inverter with the ethernet cable. It works fine. So as a "LAN only" type connection and only connected to the inverter, it works perfectly.

    Just that when I have to use the internet, I will have to change the settings back to how they were previously.

    Yet, surely an "Ethernet" connection can connect to a Local Area Network (LAN) AND the internet. I assume I need to define a default gateway like that displayed at https://www.howtogeek.com/wp-content/uploads/2017/10/sia_top.png?width=1198&trim=1,1&bg-color=000&pad=1,1 , OR use a modem/router to assign/set the static IP addresses.

    Thanks for your help Robinson. :)

    Results of ipconfig

    > Ethernet adapter Ethernet:

    Connection-specific DNS Suffix . :
    Link-local IPv6 Address . . . . . : *************************
    Autoconfiguration IPv4 Address. . : 169.254.208.24
    Subnet Mask . . . . . . . . . . . : 255.255.0.0

    As this is for a LAN, I found this article at
    https://www.digitalcitizen.life/how-set-your-networks-location-private-or-public-windows-10/  describing how to change "Public" networks to "Private"

    Then ipconfig again

    > Ethernet adapter Ethernet:

    192.168.20.1

    I'm not sure if I needed to do that prior to the instructions below ?

    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : *******************************

    and I was able to ping 192.168.1.101 , so all seemed fine until I tried to access the internet. Hmm, now no internet. Is that because I made it "Private" ??

    The Network Diagnosis states:

    > DHCP is not enabled for "Ethernet"
