Connecting to GS728TPv2 home network with CAX80 and EAX80?

I just setup the GS728TPv2 in my basement. It's on the opposite side of where my Netgear CAX80 cable modem/WiFi-6 router is located so I ran a cat8 cable to it. I have smart phones and tablets throughout the house. I have the Netgear EAX80 on the second floor which a Macbook Pro is wirelessly connected to. The Macbook Air on the first floor is connected wirelessly to the CAX80 in the basement. The cat5e ethernet cable running from the patch panel in the basement that terminates on the second floor does not work (lines 1 and 2 of the cable are open - it's a 568b setup, so I'm still troubleshooting about if I want to replace that cable).

I registered the GS728TPv2 with netgear and I was able to access the switch by directly connecting it with an ethernet cable to one of my laptops and running the Netgear Switch Discovery Tool. I was then able to change the password and access the user interface (GUI) by typing in 192.168.1.189 into the address bar in the web-browser. I've been able to access the GS728TPv2 GUI from the Mac mini in the basement, the Macbook Air via WIFI and the Macbook Pro on the second floor via WiFi.

The issue is that typing in the switch's IP address into the web browser does not always work - often times the webrowser fails to connect to the server. Also, on my Nighthawk CAX80 interface I am able to view all the devices wired and wirelessly connected to the CAX80, but the GS728TPv2 isn't listed. How do I make the GS728TPv2 show up on the CAX80's list of connected devices, and make the GS728TPv2 showup on my network app on my Macs? And what do I need to do to ensure I can seemlessly connect to the switch's GUI from any computer on my home network both via wireless and wired?

Something very basic must be wrong between the GS switch and the CAX router. Either a basic Ethernet link issue, poor wiring, poor cabling, or ports configured to another purpose.

What happens when connecting the Mac USB-Ethernet port to the port/cable/link intended for the switch connection - locally on the CAX, remote near to the switch?

PharmlyDoc,

It seems that the GS728TPv2 is set as a DHCP client. I suggest you to assign a static IP address to it. Kindly try the steps below:

1. Disconnect the GS728TPv2 from the existing network. The GS728TPv2 will go back to its default IP address which is 192.168.0.239.
2. Connect your PC/laptop to a LAN port of the GS728TPv2.
3. Set a static IP address of 192.168.0.210 on your PC/laptop.
4. Open a browser like Google Chrome or Firefox then at the address bar, type 192.168.0.239 then press Enter. Login to the user interface of switch. Enter "admin" as the username and "password" as the password without the quotation marks.
5. Click System > Management > IP Configuration.
6. On the IP Configuration page, select Static IP address. Then, enter an IP address that is within the IP Address range of your existing network in the field provided as well as the corresponding subnet mask and default gateway then click Apply.
7. Connect the GS728TPv2 back to your existing network and set the PC/laptop back to Obtain an IP address automatically.

To test the connectivity, connect your PC/laptop directly to the GS728TPv2. Open command prompt on the PC/laptop, then ping the static IP address you have set on the GS728TPv2 and ping the IP address of the router. You should be able to get replies.

  Thank you for responding. I reset the switch to factory defaults. The firmware is uptodate. I set the IP address to static as 192.168.1.189 , the subnet mask as 255.255.255.0 . But what about the default gateway? Right now the default gateway is 192.168.1.1 ,which is the IP for my CAX80. Is this correct?
  
  I am able to access the user interface of the switch if I (1) connect my laptop directly to the switch, (2) turn off the laptop's WiFi, and (3) set the IP address of the lan port for laptop to the 192.168.1.xxx range . Once I change the lan port on the laptop back to configure IPv4 using DHCP the connection to the switch GUI is lost. I am also unable to access the internet on my laptop when connected to the switch via an ethernet cable. Do I need to configure the routing settings for the switch?
  
  I also went into the Nighthawk interface for the CAX80 and reserved 192.168.1.189 for the corresponding MAC address of the switch, but that doesn't seem to have helped.
  
  Here are the ping results after setting the configuration of my laptop's IPv4 back to DHCP:
  
  Computer ~ % ping 192.168.1.189 PING 192.168.1.189 (192.168.1.189): 56 data bytes ping: sendto: No route to host ping: sendto: No route to host Request timeout for icmp_seq 0 ping: sendto: No route to host ^C --- 192.168.1.189 ping statistics --- 15 packets transmitted, 0 packets received, 100.0% packet loss

    This looks wrong to me. If the switch would not be reachable on the LAN, the response would simply timeout, but not result in a "no route to host" message. "No route to host" says this: When the destination of the ICMP message is not on the local direct connected subnet, it will be forwarded to the system default gateway to handle it. If there is no default gateway, or the gateway has no information in its routing table to forward the packets, you will see "no route to host".
