It must be on the WIN10 side because when I dug into network diagnostics it is trying to connect with my WIFI that I also use instead of the wired ethernet to a hub connecting the computer, scope, and AWG. I am able to connect the scope and AWG but not the computer and scope. I am using a wireless chip and mouse on the scope as well instead of its touch screen.

First, do some basic network troubleshooting using "ping".

On the WIN10 side,
Open a cmd window, then try to ping the scopes IP address:

C:\>ping n.n.n.n<enter>

Where n.n.n.n is the scopes IP address

report back.

What is the netmask on on the scope, and on the Windows 10 machine? Also, that screenshot doesn't show an IPv4 address, it has one, right?

Your IP configuration looks overly complex.

So…

Let’s start with the network topology.

You have a windows desktop.
It appears to have both a wired network interface adapter and a wifi network interface adapter. Is this correct?

From the info provided in post #29:
Wired Network adapter:
169.254.158.245(Preferred)
Subnet Mask . . . . . . . . . . . : 255.255.0.0

Wireless network adapter:
IPv4 Address. . . . . . . . . . . : 192.168.1.129(Preferred)
Subnet Mask . . . . . . . . . . . : 255.255.255.0

Gateway is 192.168.1.1

You must also have a hardware router that provides an Internet service connection. Correct?

The router should have two IP addresses assigned to itself.

1) an external IP address assigned to the physical network adapter connected to the internet service provider

2) an internal IP address assigned to the physical network adapter connected to your internal “private” LAN network

Each of these interfaces have an IP address and Subnet mask assigned.

What is the address and subnet mask assigned to each interface?
(you'll have to look at the router configuration to know for sure)

From info in post #29:
External:
66.118.111.57

internal:
192.168.1.1 (implied by dhcp IP assignment to wireless network adaptor)
subnet mask: 255.255.255.0

Deducing from the info in post #29:

What did you use for the scope:

IP address:
10.11.13.221 <----ok, but could have been in 192.168.1.n range

Subnet mask?
This can be 255.255.255.0

Gateway mask?
This should be 192.168.1.1

With the above noted settings, you should be able to ping without 0% loss.

Do I need to connect my local instrument intranet to the existing network? I intended for this to be a small local net.

The router should have two IP addresses assigned to itself.
Having trouble logging onto router for this info...

Nope, PC doesn't find it. Beginning to think my son may not have plugged in the computer to the hub. Not home ATM so will have to get him to check later.

I think your "instrument network" is physically isolated from your PC network.
You need to connect the instrument network to the PC network.

Usually, the router provides DHCP services to the internal network. If the router supports both wireless and wired networks, then the same "gateway' address would be auto assigned (via DHCP) to any device on the internal network, be it wired or wireless. Technically, you only have one logical internal network, so all devices should be auto assigned an IP address in the 192.168.1.n address range via DHCP.

So...in summary, this is what you should have been able to do:

First...connect the new hub to the internal PC network.
Then, verify each of your instruments support DHCP, then enable DHCP on the instrument.
Then, connect the instrument to the network and reboot it.
After it reboots, it should have obtained a new IP address assigned in the 192.168.1.n range along with subnet mask 255.255.255.0 and gateway address of 192.168.1.1.
Verify the device connectivity by using "ping" from the WIN10 PC.

Note-
If the device supports IP connectivity, but doesn't support DHCP, then you will have to manually assign a specific IP address, subnet mask, and gateway, then exclude the IP address from DHCP in the router's DHCP configuration. What I do is restrict the DHCP IP allocation range (on the router) then manually assign an IP addrees outside the allocation range to prevent conflicts.

Therein lies the rub... There is no wired network connection in my room. Looks like I will need a fast throughput 5G WIFI to ethernet extender in front of the hub. Any suggestions?

Look at TPLink devices.

They can use the AC wiring to communicate between network devices.

Each unit plugs into an AC outlet and establishes an Ethernet connection .

Why is there any need for a physical network? Why is there a need for a hub? Do all your devices support WiFi?

Configure WiFi on each device to connect to the existing WiFi network. That should be as easy as specifying the network WiFi id and providing the password.

Your device will connect to your WiFi access point (sometimes contained in the router) and the access point normally supplies all the TCP/IP configuration to the device. IP address, gateway, mask are all supplied by DHCP on the access point. I’ve connected dozens of devices all on the same network in this manner.

You can have two wireless networks on a single access point, by specifying different network named. Again, devices in either network are configured automatically.

If any device needs a static IP address, you need to exclude a range of IP addresses in your DHCP server. Once you connect with DHCP, I reconfigure the devices Ethernet settings by unchecking DHCP and adding a static address and associated mask and gateway parks. You can determine these by reviewing your DHCP settings or connecting with DHCP and manually noting the assigned setting with a command like ipconfig/all

No, they don't, that is the problem. The scope and AWG are plugged into the new hub and are communicating with each other. But for the scope to be controlled via the PC it requires a LAN connection. I do not have a wired connection in the room. Both computers are using WIFI network connections for the network printers and internet. Still need to get around to implementing backup NAS.

Look at TPLink devices.
Will do. Heard about it but no experience with it. I did go ahead and order a hi transfer speed dual band WIFI extender with 2 ethernet ports. Already have a couple in use for laptops and entertainment center. I do much prefer wired and may at some time get the housed wired for it. So TPLink may be the solution.

Do they have USB? Then you can use a WiFi dongle , like this one. A Google search for “USB WiFi dongle” turned up almost 800 products.

They do, the scope has 2 type A on the front plus a type B on the rear. The front ones are used for a mouse dongle and USB drive. The AWG has 1 type A on the front for USB drive and a type B on the rear. I first tried simply connecting the type B ports to the computer but the Bode Plot function on the scope requires a LAN connection, so... I think type B ports are for file transfer to a remote drive i.e. the PC. So, I need to use ethernet ports. Those do look interesting and would surely be better than adding a WIFI card to PCs that have USB ports available if they have decent throughput speed. I'll keep them in mind. Thanks for the heads up DJ!
